Critically Endangered Fish
As of July 2017, the International Union for Conservation of Nature (IUCN) lists 1,000 critically endangered fish species, including 87 which are tagged as ''possibly extinct''. 3.0% of all evaluated fish species are listed as critically endangered. The IUCN also lists four fish subspecies as critically endangered. Of the subpopulations of fish evaluated by the IUCN, 20 species subpopulations and one subspecies subpopulation have been assessed as critically endangered. Additionally 3191 fish species (21% of those evaluated) are listed as '' data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of ''data deficient'' indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of at ...

Oceanic Whitetip Shark
The oceanic whitetip shark (''Carcharhinus longimanus''), also known as shipwreck shark, Brown Milbert's sand bar shark, brown shark, lesser white shark, nigano shark, oceanic white-tipped whaler, and silvertip shark, is a large pelagic requiem shark inhabiting tropical and warm temperate seas. Its stocky body is most notable for its long, white-tipped, rounded fins. Though slow-moving, it is opportunistic and aggressive, and is reputed to be dangerous to shipwreck survivors. Recent studies show steeply declining populations because its large fins are highly valued as the chief ingredient of shark fin soup, and as with other shark species, the whitetip faces mounting fishing pressure throughout its range. Taxonomy The oceanic whitetip shark, or lesser white shark, was described in 1831 by naturalist René-Primevère Lesson, who named the shark ''Carcharhinus maou''. It was next described by Cuban Felipe Poey in 1861 as ''Squalus longimanus''. The name ''Pterolamiops longimanus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Smalltail Shark
The smalltail shark (''Carcharhinus porosus'') is a species of requiem shark, and part of the family Carcharhinidae. It is found in the western Atlantic Ocean, from the northern Gulf of Mexico to southern Brazil. It inhabits shallow waters close to shore, particularly over muddy bottoms around estuaries. It tends to swim low in the water column and forms large aggregations segregated by sex. A slim species generally not exceeding in length, the smalltail shark has a rather long, pointed snout, a broad, triangular first dorsal fin, and a second dorsal fin that originates over the midpoint of the anal fin base. It is plain gray in color, without prominent markings on its fins. The diet of the smalltail shark consists mainly of bony fishes such as croakers, while crustaceans, cephalopods, and smaller sharks and rays may also be consumed. It is viviparous, meaning the developing embryos are sustained by a placental connection. Females bear litters of two to 9 young on a bienni ...

Whitefin Swellshark
The whitefin swellshark (''Cephaloscyllium albipinnum'') is a little-known species of catshark, belonging to the family Scyliorhinidae, endemic to southeastern Australia. It is found down, on the outer continental shelf and upper continental slope. Reaching in length, this shark has a very thick body and a short, broad, flattened head with a large mouth. It is characterized by a dorsal color pattern of dark saddles and blotches over a brown to gray background, and light fin margins. When threatened the whitefin swellshark can inflate itself with water or air to increase its size. Reproduction is oviparous. As of 2019 The International Union for Conservation of Nature(IUCN) has assessed this species as Critically Endangered due to the significant decline of the population. Taxonomy Early specimens of the whitefin swellshark were often mistaken for the Australian swellshark (''C. laticeps'') or the draughtsboard shark (''C. isabellum'').
