Glaucus atlanticus

When I was watching videos of jellyfish off Youtube, this blue sea slug came up. It is super tiny, about 3 cm in length and feeds on the Portuguese Man o' War. Its gas filled sac in its stomach allows it to float on the surface to reach the jellies. It also absorbs the venom from the jellyfish for its own self-defense.

Super cool. Oh, and I forgot to mention it has tiny teeth!
