12. Yangtze Finless Porpoise
Status: Critically endangered. With a population estimated to be 1,000 to 1,8000, the Yangtze Finless Porpoise is the last species of dolphin in Asia’s Yangtze River.
13. Bluefin Tuna
Status: Endangered. This may surprise people for being on a list of animals that will go extinct because it’s found on so many restaurant menus. But that’s the exact reason why: This species suffers from illegal fishing — they are a delicacy for sushi and sashimi.
14. Fin Whale
Status: Endangered. The fin whale is the second-largest mammal in the world after the blue whale. They are hunted by commercial whalers for oil and meat and also suffer from environmental change (habitat loss, toxic substances, climate change).
There are more water-loving creatures on the list, but first there are some cute critters getting lost…
