"I got a sea slug! It's kinda salty about that." —New Horizons

The sea slug is a deep-sea creature found at the bottom of the sea in New Leaf and New Horizons. Diving is the only way to obtain it.

Donation to the museum

In New Leaf

In New Leaf, an information board in the aquarium will list information about this creature.

"Although they have no shells, sea slugs are more closely related to spiral shells than anything else. Their vivid colors and patterns and variety of shapes and sizes make them popular with divers. Sea slugs are hermaphrodites, so they are all capable of mating with one another, regardless of gender."

In New Horizons

In New Horizons, upon donation to the museum or selecting "Tell me more about this!", Blathers will say:

"Imagine, if you will, a land slug...but one dressed in frilly attire full of bold colors, stripes, and spots! That is the sea slug, a gastropod that looks ready to walk the red carpet...or perform beneath a big top. But these clowns are no laughing matter, eh wot. Their garish colors and wild patterns warn predators to steer clear of their stinging, toxic taste. And THAT is how you dress for success, as they say!"

Further information

Main article: Sea slug on Wikipedia

While referred to in New Leaf as a "sea slug", Hypselodoris festiva is technically a nudibranch, an aquatic mollusk similar to sea slugs though biologically different. Nudibranchs on the whole are brilliantly colored and adorned with extraordinary fringes and tentacles, the purpose of which varies: in some cases it serves as camouflage to help the animal blend in with surrounding plantlife, and in others it belays a warning to predators that the nudibranch is unpalatable or toxic.
