Inkfish

Inkfish are a form of squid that live in the waters surrounding Yuriba, especially on the side with Maboroshi. They are a hybrid of jellyfish and squid, hence the name, and typically travel in large numbers for protection. Inkfish tend to be a fluorescent blue in color, which is only apparent at night. In the daytime, they look clear and are extremely hard to find if one is intentionally seeking them out. They tend to be small, as well, though depending on how much food is around, they can grow up to three feet in length. Their appearance is closer to that of a jellyfish in many regards. They have thin tentacles that trail behind them as they move, and these tentacles are extremely delicate as they are able to be broken off when snagged on something (sharp or otherwise). True to their heritage (and name), inkfish have the ability to spew out ink as a defense mechanism. When traveling in groups, one inkfish will set off another, causing an entire area of the water to turn black.

Inkfish can also be eaten. The tentacles, though small, are very meaty and rich with nutrients. The issue is squeezing out the ink from the main body, which is also edible. The ink can also be used for writing and painting.
