Description

Urosphen was slow like Nardoechelys. Despite its slow movement, it had different ways to attack other fishes.

1. It finds a place where the fish live.
2. It swims, chases, and hunts the fish.
3. It preys on the creature and eats it.

If it weren't for the extinction of the other prehistoric Anguillidae, you might think that Urosphen would hunt other extant fish. It has a relative from Brazil and Asia called Urosphenopsis.
