A basking shark swims with its giant mouth open, feeding on plankton in the nutrient-rich waters off of Cape Cod, Massachusetts. The second largest fish in the sea - after whale sharks - this species can reach lengths of up to 30 feet long, weighing almost 5,000 pounds. Basking sharks are a close cousin of the whale shark, and can be found throughout much of the Northern Hemisphere.
Both basking sharks and whale sharks are protected in certain territorial waters, with basking sharks listed in Appendix II of the Convention on International Trade in Endangered Species (CITES), meaning that – though the species is not necessarily threatened with extinction – trade must be controlled in order to protect their survival. Earlier this week, the whale shark was upgraded to Appendix I, meaning that the species is now recognized internationally as vulnerable to extinction.
