Рыба являются жабры водоносного водных черепные животных, отсутствие конечностей с цифрами . Они образуют сестринскую группу с оболочками , вместе формируя обонятельные тела . В это определение включены живые миксины , миноги , хрящевые и костные рыбы, а также различные вымершие родственные группы. Около 99% ныне живущих видов рыб относятся к классу Actinopterygii сплавниками луча, причем более 95% относятся кподгруппе костистых рыб . Самые ранние организмы, которые можно классифицировать как рыбу, были хордовые с мягким телом, которые впервые появились в кембрийский период. Хотя у них не было настоящего позвоночника , у них были хорды, которые позволяли им быть более подвижными, чем их беспозвоночные собратья. Рыба продолжала развиваться на протяжении палеозойской эры, принимая самые разнообразные формы. Многие рыбы палеозоя обладали внешней броней , защищавшей их от хищников. Первые рыбы с челюстями появились в силурийский период, после чего многие (например, акулы ) стали грозными морскими хищниками, а не просто добычейчленистоногие .

Международный союз охраны природы (МСОП) перечислил этот вид под наименьшие опасения , так как он не ловил в значительном количестве. ( Полная статья ... ) The dusky shark ( Carcharhinus obscurus) is a species of requiem shark, in the family Carcharhinidae, occurring in tropical and warm-temperate continental seas worldwide. A generalist apex predator, the dusky shark can be found from the coast to the outer continental shelf and adjacent pelagic waters, and has been recorded from a depth of 400 m (1,300 ft). Populations migrate seasonally towards the poles in the summer and towards the equator in the winter, traveling hundreds to thousands of kilometers. One of the largest members of its genus, the dusky shark reaches 4.2 m (14 ft) in length and 347 kg (765 lb) in weight. It has a slender, streamlined body and can be identified by its short round snout, long sickle-shaped pectoral fins, ridge between the first and second dorsal fins, and faintly marked fins. Adult dusky sharks have a broad and varied diet, consisting mostly of bony fishes, sharks and rays, and cephalopods, but also occasionally crustaceans, sea stars, bryozoans, sea turtles, marine mammals, carrion, and garbage. This species is viviparous with a three-year reproductive cycle; females bear litters of 3–14 young after a gestation period of 22–24 months, after which there is a year of rest before they become pregnant again. Females are capable of storing sperm for long periods, as their encounters with suitable mates may be few and far between due to their nomadic lifestyle and low overall abundance. Dusky sharks are one of the slowest-growing and latest-maturing sharks, not reaching adulthood until around 20 years of age. ( Full article...) The coral catshark ( Atelomycterus marmoratus) is a species of catshark in the family Scyliorhinidae. It is common on shallow coral reefs across the Indo-West Pacific, from Pakistan to New Guinea. Reaching up to 70 cm (28 in) in length, the coral catshark has an extremely slender body, a short head and tail, and two dorsal fins that are angled backwards. It can be identified by the numerous black and white spots on its back, sides, and fins, which often merge to form horizontal bars. Furthermore, adult males have distinctively long and thin claspers. Reclusive and inactive during the day, at dusk and at night, the coral catshark actively forages for small, bottom-living invertebrates and bony fishes. Its slender form allows it to access tight spaces on the reef. It is oviparous; females lay purse-shaped egg capsules two at a time on the bottom, and the young hatch after 4–6 months. This small, harmless shark adapts well to captivity and has reproduced in the aquarium; it is regarded as one of the most suitable shark species for private aquarists. The coral catshark is a minor bycatch of reef fisheries, with minimal commercial value. Increasing fishing activity and extensive habitat degradation occur within its range, leading to concern over its population and its assessment as near threatened by the International Union for Conservation of Nature. ( Full article...) The winghead shark ( Eusphyra blochii) is a species of hammerhead shark, and part of the family Sphyrnidae. Reaching a length of 1.9 m (6.2 ft), this small brown to gray shark has a slender body with a tall, sickle-shaped first dorsal fin. Its name comes from its exceptionally large "hammer", or cephalofoil, which can be as wide as half of the shark's total length. The function of this structure is unclear, but may relate to the shark's senses. The wide spacing of its eyes grants superb binocular vision, while the extremely long nostrils on the leading margin of the cephalofoil may allow for better detection and tracking of odor trails in the water. The cephalofoil also provides a large surface area for its ampullae of Lorenzini and lateral line, with potential benefits for electroreception and mechanoreception, respectively. Inhabiting the shallow coastal waters of the central and western Indo-Pacific, the winghead shark feeds on small bony fishes, crustaceans, and cephalopods. It gives birth to live young, with the developing embryos receiving nourishment through a placental connection. Females produce annual litters of 6 to 25 pups; depending on region, birth may occur from February to June after a gestation period of 8–11 months. This harmless species is widely fished for meat, fins, liver oil, and fishmeal. The International Union for Conservation of Nature has assessed it as Endangered in 2016, as it is thought to have declined in some parts of its range due to overfishing. ( Full article...) A transitional fossil is any fossilized remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group. This is especially important where the descendant group is sharply differentiated by gross anatomy and mode of living from the ancestral group. These fossils serve as a reminder that taxonomic divisions are human constructs that have been imposed in hindsight on a continuum of variation. Because of the incompleteness of the fossil record, there is usually no way to know exactly how close a transitional fossil is to the point of divergence. Therefore, it cannot be assumed that transitional fossils are direct ancestors of more recent groups, though they are frequently used as models for such ancestors.
In 1859, when Charles Darwin's On the Origin of Species was first published, the fossil record was poorly known. Darwin described the perceived lack of transitional fossils as, "... the most obvious and gravest objection which can be urged against my theory," but explained it by relating it to the extreme imperfection of the geological record. He noted the limited collections available at that time, but described the available information as showing patterns that followed from his theory of descent with modification through natural selection. Indeed, Archaeopteryx was discovered just two years later, in 1861, and represents a classic transitional form between earlier, non-avian dinosaurs and birds. Many more transitional fossils have been discovered since then, and there is now abundant evidence of how all classes of vertebrates are related, including many transitional fossils. Specific examples of class-level transitions are: tetrapods and fish, birds and dinosaurs, and mammals and "mammal-like reptiles". (Full article...) The dark shyshark or pretty happy ( Haploblepharus pictus) is a species of catshark, belonging to the family Scyliorhinidae, endemic to the temperate waters off southern Namibia and western South Africa. It is benthic in nature and inhabits shallow, inshore waters and favors rocky reefs and kelp forests. Growing to 60 cm (24 in) long, this small, stocky shark has a wide, flattened head with a rounded snout and a large flap of skin extending from before the nostrils to the mouth. Its dorsal coloration is extremely variable and may feature black-edged orange to blackish saddles and/or white spots on a light brown to nearly black background. When threatened, the dark shyshark curls into a ring with its tail covering its eyes, hence the name "shyshark". It preys mainly on small crustaceans, bony fishes, and molluscs. Reproduction is oviparous and proceeds throughout the year. Females lay two egg cases at a time, which hatch after 6–10 months. This harmless species is of little commercial significance due to its small size. It is frequently caught by recreational fishers and persecuted as a pest. The International Union for Conservation of Nature (IUCN) has listed the dark shyshark under Least Concern, as it is common and does not appear to be substantially threatened by fishing or habitat degradation. ( Full article...) The milk shark ( Rhizoprionodon acutus) is a species of requiem shark, and part of the family Carcharhinidae, whose common name comes from an Indian belief that consumption of its meat promotes lactation. The largest and most widely distributed member of its genus, the milk shark typically measures 1.1 m (3.6 ft) long, and can be found in coastal tropical waters throughout the eastern Atlantic and the Indo-Pacific regions. Occurring from the surface to a depth of 200 m (660 ft), this species is common near beaches and in estuaries, and has been recorded swimming up rivers in Cambodia. Juveniles are known to inhabit tidal pools and seagrass meadows. The milk shark has a slender body with a long, pointed snout and large eyes, and is a nondescript gray above and white below. This shark can be distinguished from similar species in its range by the long furrows at the corners of its mouth, and seven to 15 enlarged pores just above them. Among the most abundant sharks within its range, the milk shark feeds primarily on small bony fishes, but also takes cephalopods and crustaceans. In turn, it often falls prey to larger sharks and possibly marine mammals. In common with other members of its family, this species is viviparous, with the developing embryos sustained by a placental connection. Females give birth to one to eight young either during a defined breeding season or throughout the year, depending on location. The reproductive cycle is usually annual, but may be biennial or triennial. Large numbers of milk sharks are caught by artisanal and commercial fisheries in many countries for meat, fins, and fishmeal. The International Union for Conservation of Nature has assessed this species as being vulnerable. ( Full article...) The Philadelphia Inquirer reported the capture of a "man-eating" shark off the Jersey Shore after the attacks. The Jersey Shore shark attacks of 1916 were a series of shark attacks along the coast of New Jersey, in the United States, between July 1 and 12, 1916, in which four people were killed and one injured. The incidents occurred during a deadly summer heat wave and polio epidemic in the United States that drove thousands of people to the seaside resorts of the Jersey Shore. Since 1916, scholars have debated which shark species was responsible and the number of animals involved, with the great white shark and the bull shark most frequently cited. Personal and national reaction to the fatalities involved a wave of panic that led to shark hunts aimed at eradicating the population of "man-eating" sharks and protecting the economies of New Jersey's seaside communities. Resort towns enclosed their public beaches with steel nets to protect swimmers. Scientific knowledge about sharks before 1916 was based on conjecture and speculation. The attacks forced ichthyologists to reassess common beliefs about the abilities of sharks and the nature of shark attacks. ( Full article...) The mangrove whipray ( Urogymnus granulatus) or whitetail stingray, is a species of stingray in the family Dasyatidae. It is widely distributed in the Indo-Pacific region from the Red Sea to northern Australia and Micronesia. A benthic inhabitant of shallow inshore waters, juvenile mangrove whiprays favor mangrove and estuarine habitats, while adults favor sandy to rocky areas in lagoons and coral reefs. This species can be identified by its thick, oval pectoral fin disc that is dark gray above with numerous white flecks, and by its relatively short, whip-like tail that is white past the stinging spine. It grows up to 1.4 m (4.6 ft) across. Solitary in nature, the mangrove whipray preys mainly on small, bottom-dwelling bony fishes and invertebrates. It is, like other stingrays, aplacental viviparous, with the females nourishing their unborn young via histotroph ("uterine milk"). The mangrove whipray is caught for its meat, skin, and cartilage across much of its range. The International Union for Conservation of Nature (IUCN) has assessed it as Vulnerable globally and as Endangered in Southeast Asia, where its population has declined substantially due to intensive artisanal and commercial fisheries as well as widespread habitat degradation. In particular, juvenile rays have been disproportionately targeted by fishers and affected by the large-scale destruction of mangrove forests. ( Full article...) The porbeagle ( Lamna nasus) is a species of mackerel shark in the family Lamnidae, distributed widely in the cold and temperate marine waters of the North Atlantic and Southern Hemisphere. In the North Pacific, its ecological equivalent is the closely related salmon shark ( L. ditropis). It typically reaches 2.5 m (8.2 ft) in length and a weight of 135 kg (298 lb); North Atlantic sharks grow larger than Southern Hemisphere sharks and differ in coloration and aspects of life history. Gray above and white below, the porbeagle has a very stout midsection that tapers towards the long, pointed snout and the narrow base of the tail. It has large pectoral and first dorsal fins, tiny pelvic, second dorsal, and anal fins, and a crescent-shaped caudal fin. The most distinctive features of this species are its three-cusped teeth, the white blotch at the aft base of its first dorsal fin, and the two pairs of lateral keels on its tail. The porbeagle is an opportunistic hunter that preys mainly on bony fishes and cephalopods throughout the water column, including the bottom. Most commonly found over food-rich banks on the outer continental shelf, it makes occasional forays both close to shore and into the open ocean to a depth of 1,360 m (4,460 ft). It also conducts long-distance seasonal migrations, generally shifting between shallower and deeper water. The porbeagle is fast and highly active, with physiological adaptations that enable it to maintain a higher body temperature than the surrounding water. It can be solitary or gregarious, and has been known to perform seemingly playful behavior. This shark is aplacental viviparous with oophagy, developing embryos being retained within the mother's uterus and subsisting on non-viable eggs. Females typically bear four pups every year. ( Full article...) The great hammerhead ( Sphyrna mokarran) is the largest species of hammerhead shark, belonging to the family Sphyrnidae, attaining an average length of 4.6 m (15 ft) and reaching a maximum length of 6.1 m (20 ft). It is found in tropical and warm temperate waters worldwide, inhabiting coastal areas and the continental shelf. The great hammerhead can be distinguished from other hammerheads by the shape of its "hammer" (called the "cephalofoil"), which is wide with an almost straight front margin, and by its tall, sickle-shaped first dorsal fin. A solitary, strong-swimming apex predator, the great hammerhead feeds on a wide variety of prey ranging from crustaceans and cephalopods, to bony fish, to smaller sharks. Observations of this species in the wild suggest that the cephalofoil functions to immobilize stingrays, a favored prey. This species has a viviparous mode of reproduction, bearing litters of up to 55 pups every two years. Although potentially dangerous, the great hammerhead rarely attacks humans. It sometimes behaves inquisitively toward divers and should be treated with respect. This shark is heavily fished for its large fins, which are extremely valuable on the Asian market as the main ingredient of shark fin soup. As a result, great hammerhead populations are declining substantially worldwide, and it has been assessed as Critically Endangered by the International Union for Conservation of Nature (IUCN) as of 2019. ( Full article...) The Japanese sleeper ray ( Narke japonica) is a species of electric ray in the family Narkidae. It is common in the inshore and offshore waters of the northwestern Pacific Ocean from southern Japan to southern China. Growing up to 40 cm (16 in) long, the Japanese sleeper ray has a nearly circular pectoral fin disc colored reddish to chocolate brown above, sometimes with darker or lighter spots, and lighter brown below. The spiracles behind its small eyes have raised, smooth rims. Its short and muscular tail bears a single dorsal fin positioned aft of the rounded pelvic fins, and terminates in a large caudal fin. Inhabiting shallow, sandy areas near rocky reefs, the Japanese sleeper ray is a bottom-dwelling predator of invertebrates. Like other members of its family, it can produce a strong electric shock from its electric organs for defensive purposes. Females give live birth to litters of up to five pups. The gestating young are sustained at first by yolk, and later by histotroph ("uterine milk"). The International Union for Conservation of Nature (IUCN) has listed this species as Vulnerable, due to its susceptibility to trawl fisheries that operate intensively throughout its range. ( Full article...) Bowfin ( Amia calva) are bony fish related to gars in the infraclass Holostei. Common names include mudfish, mud pike, dogfish, griddle, grinnel, swamp trout, and choupique. They are regarded as taxonomic relicts, being the sole surviving species of the order Amiiformes, which dates from the Jurassic to the Eocene, persisting to the present. Although bowfin are highly evolved, they are often referred to as "primitive fish" because they have retained some morphological characteristics of their early ancestors. Bowfin are demersal freshwater piscivores native to North America, and commonly found throughout much of the eastern United States, and in southern Ontario and Quebec. Fossil deposits indicate Amiiformes were once widespread in both freshwater and marine environments with a range that spanned across North and South America, Europe, Asia and Africa. Now their range is limited to much of the eastern United States and adjacent southern Canada, including the drainage basins of the Mississippi River, Great Lakes and various rivers exiting in the Eastern Seaboard or Gulf of Mexico. Their preferred habitat includes vegetated sloughs, lowland rivers and lakes, swamps and backwater areas; they are also occasionally found in brackish water. They are stalking, ambush predators known to move into the shallows at night to prey on fish and aquatic invertebrates such as crawfish, mollusks, and aquatic insects. ( Full article...) The bluespotted stingray ( Neotrygon kuhlii), also known as the bluespotted maskray or Kuhl's stingray, is a species of stingray of the family Dasyatidae. It was recently changed from Dasyatis kuhlii in 2008 after morphological and molecular analyses show that it is part of a distinct genus, Neotrygon. The body is rhomboidal and colored green with blue spots. Maximum disk width is estimated 46.5 centimeters (18.3 in). It is popular in aquaria but usually not distinguished from the bluespotted ribbontail ray. The ribbontail has a rounded body, is a brighter green with brighter blue and more vivid spots, but the bluespotted stingray is larger. The stingray's lifespan is estimated thirteen years of age for females and ten years for males. The bluespotted stingray preys on many fish and small mollusks. The bluespotted stingray is also generally found from Indonesia to Japan, and most of Australia. The bluespotted stingray is also targeted by many parasites such as tapeworms, flatworms, and flukes. ( Full article...) The great white shark ( Carcharodon carcharias), also known as the great white, white shark or white pointer, is a species of large mackerel shark which can be found in the coastal surface waters of all the major oceans. It is notable for its size, with larger female individuals growing to 6.1 m (20 ft) in length and 1,905–2,268 kg (4,200–5,000 lb) in weight at maturity. However, most are smaller; males measure 3.4 to 4.0 m (11 to 13 ft), and females measure 4.6 to 4.9 m (15 to 16 ft) on average. According to a 2014 study, the lifespan of great white sharks is estimated to be as long as 70 years or more, well above previous estimates, making it one of the longest lived cartilaginous fishes currently known. According to the same study, male great white sharks take 26 years to reach sexual maturity, while the females take 33 years to be ready to produce offspring. Great white sharks can swim at speeds of 25 km/hr (16 mph) for short bursts and to depths of 1,200 m (3,900 ft). The great white shark has no known natural predators other than, on very rare occasions, the killer whale. It is arguably the world's largest-known extant macropredatory fish, and is one of the primary predators of marine mammals, up to the size of large baleen whales. This shark is also known to prey upon a variety of other marine animals, including fish, and seabirds. It is the only known surviving species of its genus Carcharodon, and is responsible for more recorded human bite incidents than any other shark. ( Full article...)
Больше избранных статей Выбранная рыба - покажи другуюБоуфин ( Amia calva ) - костлявые рыбы, родственные гарам в инфраклассе Holostei . Распространенные названия включают ил, грязевую щуку, морскую рыбу, сковородку, гриннель, болотную форель и шупик. Они рассматриваются как таксономические реликты , являясь единственным выжившим видом отряда Amiiformes , который датируется юрским периодом до эоцена и сохранился до настоящего времени. Хотя боуфины высоко развиты, их часто называют « примитивными рыбами », потому что они сохранили некоторые морфологические характеристики своих ранних предков . Боуфин - донное пресноводное рыбоядное животное, обитающее в Северной Америке, и обычно встречается на большей части восточной части Соединенных Штатов , а также в южном Онтарио и Квебеке . Отложения окаменелостей указывают на то, что Amiiformes когда-то были широко распространены как в пресноводных, так и в морских средах, а их диапазон охватывал Северную и Южную Америку, Европу, Азию и Африку. Теперь их ареал ограничен большей частью восточной части Соединенных Штатов и прилегающей южной Канадой, включая водосборные бассейны реки Миссисипи , Великие озера и различные реки, выходящие на восточное побережье или Мексиканский залив.. Их предпочтительная среда обитания включает покрытые растительностью болота, равнинные реки и озера, болота и заводи; они также иногда встречаются в солоноватой воде. Они преследуют и устраивают засаду хищникам, которые, как известно, ночью уходят на мелководье, чтобы охотиться на рыб и водных беспозвоночных, таких как раки, моллюски и водные насекомые.

Reaching about 110 mm (4.3 in) in length, the species may have a range of colors. After clownfish hatch, they initially reside near the surface. When they become juveniles, however, they move to the seafloor to find a host anemone, forming a symbiotic relationship in which they obtain protection in return for defense.

More selected pictures Round ribbontail ray Photograph credit: Rucha Karkarey; edited by John HarrisonThe round ribbontail ray (Taeniura meyeni) is a species of stingray in the family Dasyatidae, found throughout the nearshore waters of the tropical Indo-Pacific region. Reaching 1.8 m (6 ft) across, this large ray is characterized by a thick, rounded pectoral fin disc covered by small tubercles on top, and a relatively short tail bearing a single venomous spine. The ray is well-camouflaged when lying on the seabed; it is largely nocturnal, and preys on molluscs, crustaceans and bony fish. Mature females bear litters of up to seven pups, which are fed during gestation on "uterine milk", a product secreted by the walls of the oviduct. This round ribbontail ray was photographed in Lakshadweep, India.

It has a thin, disc-shaped body, and male can grow up to 50 centimetres (20 in) in length. In the wild, the orbicular batfish lives in brackish or marine waters, usually around reefs, at depths from 5 to 30 metres (20 to 100 ft). It is also a popular aquarium fish, although captive specimens generally do not grow as long as wild ones. More selected pictures Spotted trunkfish Photograph credit: Betty WillsThe spotted trunkfish (Lactophrys bicaudalis) is a species of ray-finned fish in the family Ostraciidae, native to the Caribbean Sea and parts of the western Atlantic Ocean. Members of this family are known as boxfishes because they have a hard outer covering consisting of hexagonal, plate-like scales fused together into a solid, triangular or box-like carapace. Because of this casing, the body of the spotted trunkfish is not flexible, and locomotion is normally limited to slow movements performed by rippling its dorsal and anal fins and gently beating its pectoral fins. If faster motion is required, it can additionally use its caudal fin for propulsion. This spotted trunkfish was photographed at a depth of about 40 ft (12 m) at Bari Reef, Bonaire.
