Found mostly off the coast of Tasmania and Australia, the rare handfish are solitary, slow-moving creatures. They use their fins to walk on the seafloor, rather than swimming. They could be our ancestors, before we emerged from the sea.
National Geographic has a series of articles on these fish, which are spotted so infrequently that it's been hard for scientists to study them. There are only 14 species of handfish, and they lay very few eggs. Most are endangered.
They eat by wandering very slowly across the seafloor, eating worms and crustaceans. Though they make an easy target for predators, they manage to escape being eaten because they have extremely toxic skin.
