Quick Answer
A nudibranch is a type of shell-less sea slug known for bright colors and unusual body forms. Many species are predators or specialize in eating sponges, hydroids, or other small animals.
The Full Story
Nudibranchs are gastropod mollusks, related to snails, but they lose the shell in the adult stage. Their vivid colors often signal toxicity or warn predators that they have unpleasant defenses. Some species steal stinging cells from prey and use them for their own protection. Because they are highly diverse and often spectacularly colored, nudibranchs are popular subjects for underwater photographers and marine biologists.
