We are alarmed by the recent decision by the National Marine Fisheries Service (NMFS) not to provide needed protections for U.S. West Coast great white sharks under the federal Endangered Species Act. NMFS declined protections despite current science estimates of only a few hundred sub-adult and adult white sharks at their primary aggregation sites. The Endangered Species Act (ESA) petition submitted by Oceana and its partners to NMFS met all the legal criteria and demonstrated through the best available science that this special population of great white sharks clearly warrants protections under the ESA.
We often tell you about the threats facing sharks globally -- finning, bycatch, overfishing -- but we don’t regularly shine a spotlight on the individual species affected.
To continue our ongoing shark-themed posts in honor of Shark Week, here are 10 of the most threatened shark species in the world:
1. Basking sharks are the second largest shark, easily distinguished by their huge, filter-feeding mouths. Basking sharks are caught in target fisheries around the world for their oil, meat and fins, and they are also caught as bycatch in other fisheries.
2. Blue sharks are one of the most previously abundant shark species. Now they are the most heavily fished shark in the world. An estimated 10-20 million individuals are killed by fisheries annually, mostly as bycatch. Blue shark meat is beginning to replace swordfish in many Mediterranean countries and the fins are commonly used in shark fin soup.
3. Deep-sea sharks have huge livers that contain high amounts of oil to regulate their buoyancy at depths. As a result, they are caught by deep-sea trawls, gillnets and longlines for an oily substance found in their livers called squalene. Squalene, or its derivative squalane, is found in many cosmetic products.
