Gilltails (General)

Gilltails are a fish-like group of Binucleozoa.

Breathing and Blood
Gilltails have gill filled tubes that run through their bodies, water enters through an opening under the beak and exits through holes or slits on the sides of the body, usually near the back end. Their blood is red like their beakworm ancestors.

Locomotion
Gillworms swim through the water by moving their bodies in a side to side waving motion.
