This snailfish’s fins look wing-like and majestic, but the only flying it will do is 7,000 feet underwater. The Glaucus Atlanticus Sea Slug, pictured twice above, is breath-taking, and really really small. It certainly looks cute compared to the Long-Nosed Chimera, which surfs along the ocean floor using its nose to gather up prey in the sand.
