In 2013, the species was added to Appendix II of the Convention on International Trade in Endangered Species (CITES), and in 2018, it was added to Annex 1 of the Convention on Migratory Species (CMS) Memorandum of Understanding (MoU) for Migratory Sharks. The IUCN has thus listed the oceanic whitetip shark as critically endangered, but efforts have been made to conserve the species. One study found that oceanic whitetip shark populations have declined by 71% between 19. The high demand for this shark's skin, meat, and fins has led to overfishing that has caused a sharp decline in population numbers. It is also valued for its skin, which is used for leather. A popular food source, the oceanic whitetip shark is used by humans for its meat and oil, and its fins are often used in shark fin soup. ![]() The oceanic whitetip shark ( Carcharhinus longimanus) is found throughout the world's oceans between the latitudes of 45 degrees north and 43 degrees south. However, despite these efforts, populations still remain critically low. Soon after, in 2010, the EU made it illegal to catch angelsharks in the coastal waters of any member countries, and in 2011, catching the angelshark in the Mediterranean Sea was also made illegal. In 2008, the UK government made it illegal to catch angelsharks in the waters surrounding England and Wales. Today, the IUCN lists the angelshark as critically endangered, but efforts are being made to conserve the species. Furthermore, the species is believed to be extinct in the northern Mediterranean Sea as well as in the North Sea, two areas that once hosted abundant angelshark populations. Over the past 45 years, global angelshark populations are estimated to have declined by 80-90%. Angelsharks also have low reproduction rates and are often accidentally caught in fishing nets as by-catch, which further contributed to population declines. Unfortunately, the high demand for angelshark meat led to overfishing, which decimated angelshark populations. For the next 2,000 years, the angelshark remained a popular source of meat, fishmeal, and shark liver oil throughout Europe. Ancient Greek authors and physicians such as Aristotle, Mnesitheus, and Diphilus as well as the Ancient Roman author Pliny the Elder have mentioned the angelshark in their works, noting the appeal of its meat as a food source and the usefulness of its skin as a means of polishing ivory and wood. The angelshark ( Squatina squatina) has lived in the coastal waters of Western Europe and Northern Africa for thousands of years, and populations used to be plentiful. ![]()
