"I caught a sea butterfly! I didn't even use a net!" —New Leaf

The sea butterfly (クリオネ, Kurione?), are a species of mollusk 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 Wild World, and has appeared in every game since.

Donation to the museum

The sea butterfly can be donated to the Museum by talking to Blathers. Below is what is says during the donation:

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.

In New Leaf

"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 this game."

Further information

Sea Butterfly

A real-life sea butterfly.

Sea butterflies are a kind of sea snail with the ability to swim. They beat their wing-like flippers to fly through the water not unlike butterflies, hence their name. They are very small - only 1cm in length, but play a significant role in the food web of the oceans. They can be found within the upper layers of the ocean all over the world, but are more common in cold waters, such as those at the poles.
