Janthina janthina

Group: Other
Typical depth: 1–2 m
Max size: 3.7 cm

A purple sea snail that lives upside down at the very surface of the open ocean, it hangs from a raft of trapped air bubbles it makes by churning mucus with its foot. Cut loose from the bottom entirely, it drifts wherever the wind and current carry it, hunting the floating siphonophores it preys on.
