What animal in the animal kingdom were you most surprised was considered an animal?

The Pig-nose frog

Explanation:

Personally, I find these animals creepily amazing. The pig-nose frog goes by a few names, starting with purple frog, Indian purple frog, and pig frog. It looks mostly like a blob-fish then a frog, really. "The pig frog is green or grey-green in color, with brown or black blotching. It has fully webbed feet, a sharply pointed nose, and large tympana (eardrums). It is easily mistaken for various other species of the genus Litho-bates , with which it shares its geographic range, including the American bullfrog." "The body of the purple frog appears robust and bloated and is relatively rounded compared to other more dorsoventrally-flattened frogs. Its arms and legs splay out in the standard anuran body form. Compared to other frogs, purple frogs have a small head and an unusual, pointed snout."
