Blue Glaucus
Glaucus atlanticus
- Group: Nudibranch
- Typical depth: 0–37 m
- Max size: 4 cm
- For divers: dangerous
The blue glaucus floats upside down at the surface, kept afloat by a swallowed bubble of air, and preys on the Portuguese man o war. It stores the stinging cells from its victims in its own frilly tips, so a bare hand that brushes it can be stung hard.
