Sea butterfly

The Sea Butterfly (クリオネ, Kurione) is a fish introduced in. They can be caught in the ocean during winter and are the only winter fish that cast such a small shadow in the sea and so, can be identified easily.

Donating to the museum
The Sea Butterfly can be donated to the Museum by talking to Blathers. Below is what he says during the donation:

In

 * "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.

The Sea Butterfly is placed in the large ocean tank in the aquatic display in the back room.

In City Folk
It occupies a large glass tube in the lower-right corner of the fish exhibition, with other small oceanic fish.

In New Leaf
Upon donation, the information board outside the tank that houses the Sea Butterfly says:


 * "Sea butterflies go with the flow, as they'll drift in cold winter waters along the 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 this game."

In

 * Such mystery! Such grace! Did you know that the sea butterfly's scientific name is Thecosomata? A very rough translation of that is "shell body." Indeed, this illustrious creature is related to snails! However, it reminds me much more of an elegant feathered friend, the way it flies through the water. With such grace in flying, one shouldn't wonder if it's related to the owl, hoo hoo!

When the Sea Butterfly is donated, six of them will appear in the northern room of the fish exhibit, in a tall tubular tank with a light blue crystal. It is one of the few fish which the museum will have multiple of upon its donation.
