Squid

The Squid is a fish that can be found in the ocean between December and mid-August, at any time of the day. Despite it being called a fish in, it is infact a type of mollusc (Europe) / mollusk (US) , like (but not directly related to) the Octopus.

Donating to the Museum
Squid can be donated to the museum: when given to Blathers, he will briefly talk about the Mollusk.

In Wild World
"Octopus and squid both have ink, and I've seen squid ink in recipes quite often... Strangely, however, I've never heard of a dish that uses octupus ink! I suppose it's partially due to the fact that octopi produce very little ink... What ink they DO make is watery and ill-suited for cooking, as well... That said, I've heard that the flavor is not at all repugnant, eh wot? Perhaps an octopus-ink pasta wouldn't be bad..."

After being given to the museum, the squid will appear in the ocean tank of the aquarium, propelling itself around towards the back.

In New Leaf
The information board in front of the tank that houses the squid says:


 * "People assume squids have legs, but those are actually arms. There are 10 in all; two are used to grab prey. To swim, they twist their fins and expel water from inside their bodies to allow for fluid motion. The ink they shoot when threatened forms into the shape of a squid, acting as a sort of body double."

Encyclopedia Information

Further Information
The type of squid in Animal Crossing isn't mentioned, but judging by the in-built City Folk description, it maybe a European Squid which is white with two long arms. The family name,  'Loliginidae'  is commonly refered to as the inshore, calamari, and grass squid. Squid eat small plants, insects and small animals that float on the surface of the ocean.
