Ray

The Ray (エイ, Ei) is a flat brown fish found in the ocean. The fish is large, giving it a huge shadow. It is a quite expensive fish, selling for 3,000 Bells. City Folk has stated that "freshwater types of these relatives of sharks are popular pets." When placed in the museum, like all other saltwater fish, except for the small ones, it appears in the very back tank.

Donating to the Museum
As with all fish in the, the ray can be donated to the Museum by talking to Blathers, who will give a small talk about it. It can be found in the back oceanic tank, with other ocean fish.

In City Folk
Blathers has this to say about the ray when it is donated:

"Many theorize that rays are distant relatives to the sharks... But unlike their fearsome theoretical cousins, rays, with their little grins, are simply adorable, wot wot!"

In New Leaf
After donating a ray to Blathers, it will appear in the section for fish and deep sea creatures, specifically in the top-right most tank in the north-eastern room.

"Beating their large fins up and down to move through the water almost gives rays the impression of flying. If viewed from below, rays appear to have their mouths curled up into a sort of smile. Some varieties have poisonous spikes at the base of their long tail fins that can be fatal to humans. This, combined with the ability to hide in sand at the bottom of the sea, can make them very dangerous."

Encyclopedia Information
Whenever the player catches a fish or bug, they can find information about it in the fish encyclopedia.
