Endangered Fish
In September 2016, the International Union for Conservation of Nature (IUCN) listed 643 endangered fish species. Of all evaluated fish species, 4.2% are listed as endangered. The IUCN also lists ten fish subspecies as endangered. Of the subpopulations of fishes evaluated by the IUCN, 24 species subpopulations have been assessed as endangered. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered fishes are listed separately. There are 1098 fish species which are endangered or 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 distrib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caribbean Reef Shark
The Caribbean reef shark (''Carcharhinus perezi'') is a species of requiem shark, belonging to the family Carcharhinidae. It is found in the tropical waters of the western Atlantic Ocean from Florida to Brazil, and is the most commonly encountered reef shark in the Caribbean Sea. With a robust, streamlined body typical of the requiem sharks, this species is difficult to tell apart from other large members of its family such as the dusky shark (''C. obscurus'') and the silky shark (''C. falciformis''). Distinguishing characteristics include dusky-colored fins without prominent markings, a short free rear tip on the second dorsal fin, and tooth shape and number. Measuring up to long, the Caribbean reef shark is one of the largest apex predators in the reef ecosystem, feeding on a variety of fishes and cephalopods. They have been documented resting motionless on the sea bottom or inside caves, unusual behavior for an active-swimming shark. If threatened, it may perform a threat d ...

The reported size of females has decreased when compared with previous recordings of the species, with the new maximum size of females being around , while the reported size of males has increased. Another way to tell males and females apart is by looking at the end of their pelvic fins, as males possess calcified claspers (exter ...
