Lump Sucka!

They live in the colder waters of the Pacific Ocean, and most of the research on them thus far has been done by Russian scientists. Their pectoral fins have been modified into a sucker that allows them to chill out and hang on to stuff. They have the ability to change color, and look like a cross between a sculpin and a puffer fish. Other than that, not much is known about these small, orb-shaped fish.
Behold, the mighty lumpsucker!
