Bali has a spectacular variety of these colorful marine creatures. The name
Nudibranch is from the Latin description and means "naked gill", most of these have
exposed feathery gills they use to breathe. Some are six inches in length, others are a
quarter inch or less. Most of them are brilliantly colored as a warning signal. Many
of them eat poisonous stinging hydroids and absorb the toxins as a defense. The
coloration advertises what they are--and after mouthful number one, any potential
predator is going to stay away from anything like it.
