The criteria are designed to cover important aspects of shark biology (e.g., age, growth and reproduction), ecology and population structure, and include multiple aspects of species vulnerability, distribution and movement patterns, abundances, specific habitat requirements and key life-cycle activities, as well as areas of high diversity and ...
In a milestone decision in 2013, CITES prohibited international trade in the fins of the scalloped hammerhead (pictured) and four other shark species. [5] Shark species are increasingly becoming threatened because of commercial and recreational fishing pressures, the impact of non-shark fisheries on the seabed and shark prey species, and other ...

This rarely encountered shark swims close to the bottom of the seafloor, typically at depths of 400–900 m (1,300–3,000 ft), though it may ...
This species inhabits areas with poor visibility, soft bottoms, and large tides, with immature sharks ranging into fresh and brackish water.

Furthermore, this shark has prominent black tips on its pectoral fins, second dorsal fin, and caudal fin lower lobe. The Pondicherry shark is critically endangered. It was once found throughout Indo-Pacific coastal waters from the Gulf of Oman to New Guinea, and is known to enter fresh water. Fewer than 20 specimens are available for study, and ...
Students at the University of North Florida, under the direction of James Gelsleichter who is authorized by a permit to handle the endangered species, caught a smalltooth sawfish in the St. Marys ...
The non-mammal species with the highest EDGE score is the largetooth sawfish (7.4). The species with the highest ED scores are the pig-nosed turtle (149.7) and the narrow sawfish (125.1). Examples of Critically Endangered species with very low ED scores are porites pukoensis, mountainous star coral, and the magenta petrel. [10]
