Unlike most dolphins, males are the pinkest! The more fights they win, the rosier they get. Sounds a bit tough on the skin, but it seems to impress the lady dolphins. Except for freshwater sharks, such as the bull shark, these dolphins are the apex predators in their river habitats.

Sadly, these Amazon ambassadors are facing some threats. Pollution and habitat loss are making their home less happy. But don't worry, people are working hard to protect them. So next time you see a dolphin show, remember the amazing pink acrobats of the Amazon!
