Sealid

The sealid split from its ancestor the globe gilltail. It has specialized in eating the roots of the polar hummroot and lurehum. Its short, strong beak allows it to bite off chunks the roots. They are an important part of the ecosystem because they create swimming paths among the roots for larger gilltails to swim through. Juveniles on the other hand will hide from predators among the roots. The adults will even lay their eggs in the sand near the roots so larger predators cannot get to them. Its fins have gotten stronger so it can swim away from predators faster. They have developed a 3rd jaw that is used to block its front gill opening. This helps protect it from parasites like the bleedin waterworm which might try to get into it.
