Glaucus atlanticus (commonly known as the sea swallow, blue angel, and blue dragon) is a small, blue, pelagic sea slug.

Glaucus atlanticus: beautiful blue sea slug, or Pokemon?

For starters, what about the fact that they're basically moving fortresses? Okay, maybe this doesn't impress you. Turtles have the same thing going for them, after all. Read more →
