@armanharutyunyan_0: Vaquita (World’s Rarest Marine Mammal) Location: Gulf of California, Mexico Estimated Left: Fewer than 10 🐬 Story: The vaquita is a tiny porpoise with dark rings around its eyes. It wasn’t even discovered until 1958, and by the time scientists understood it, it was already disappearing. The biggest threat is illegal fishing nets used for catching the totoaba fish. Vaquitas get trapped and drown. Today, it’s the rarest marine mammal alive — so rare that many researchers fear every sighting could be the last.
