The marine Jamoytius had a narrow, tubular shape with a long fin on its back. It also haves a pair of lateral fins running along its flanks and a small anal fin. The strong downturned tail produces the uplift.

Jamoytius had a round, suckerlike mouth and it was probably a parasite like its living descendant, the marine lamprey. This jawless fish attaches itself to other fishes, rasps away their flesh and then sucks their blood.
