A hard-shelled sea creature named Colymbosathon Ecplecticos is the oldest known species with a penis. Its name means "amazing swimmer with large penis" in Greek.

Frogs use their sticky, muscular tongue to catch and swallow food. Unlike humans, their tongue is not attached to the back of its mouth. Instead it is attached to the front, enabling the frog to stick its tongue out much further.

There are dolphins that live in the Amazon River that are the colour pink.
