Fish

Fish are cold-blooded aquatic vertebrates. Fish are often used for food.

Some eel-like creatures were seen swimming in a lake on Archer IV. (ENT: "Strange New World")

There's a large tank on the Xyrillian ship. Eel-like creatures can be seen swimming in the liquid through windows. (ENT: "Unexpected")

It is unknown, what function these fish serve or what liquid they are swimming in. It can't be water, because we find out in the episode, that the Xyrillians have trouble producing water and that solid gelatinous cubes is the closest to water they can come up with...
