Deep eel

Deep eels are a species of non-sentient species of eel that dwelled deep within the caverns of Acra.

Anatomy
They are so named because they live in the deeper parts of caverns in deep holes called eel holes. They are carnivorus and hunt cavern fish and cavern spiders that are foolish enough to get to close to eel holes. They have rows of glowing blue lights on their sides, a forked tail, no eyes, spikes gowing along their backs and a maws filled with large sharp teeth. They can grow up to 3 feet in length. Despite their fierce dispositions they can be hunted and eaten by Kegans and Acran Magna dragoons and are considered delicacies.
