Sea Butterflies (Order Gastropoda; Clione limacina), are a species of mollusk/mollusc that live in the sea. They can be caught during winter and are the only winter fish that cast such a small shadow in the sea, and so can be identified with ease. Its appearance during winter is a reference to how it is found in cold waters in real life.
The Sea Butterfly was first introduced in Animal Crossing: Wild World, and has appeared in every game since.

In Wild World
The sea butterfly is in the same family as snails, as you may or may not know. You might think it's strange to have a snail without a shell, eh wot? Indeed, well, slugs are also snails without shells! I must admit, being lumped in with slugs probably angers the sea butterfly
In City Folk
It occupies a large glass tube in the lower-right corner of the fish exhibition, with other small oceanic fish.

Sea butterflies go with the flow, as they'll drift in cold winter waters along with ice floes. They are called "ice-floe angels" because of the mysterious way they swim with their winglike arms. Their heads will open up when they make an attempt to catch their helpless prey. Once its head is opened, it grabs its prey with six special feelers called "buccal cones." The only place you'll find both cold water and tropical sea butterflies swimming together is in the game.

The name Sea Butterfly often causes confusion. The true Sea Butterflies are a distantly related cousin of Sea Angels (the latter of which appears in Animal Crossing under the name Sea Butterfly). Where Sea Angels are shell-less mollusks with a close resemblance to slugs, true Sea Butterflies retain their shells and look more like deep sea snails. However, the name Sea Butterfly has widely been used for both, as Sea Angels are occasionally called Naked Sea Butterfly as a reference to its lack of shell.
Sea angels can be found in the cold waters of the Arctic Ocean, Antarctic Ocean and in the North Atlantic; mirrored, in-game, by their appearance during the winter months. They can grow up to 5 centimeters in length.
