From Sagan 4 Alpha Wiki
Gilltails are a fish-like group of Binucleozoa.
Anatomy

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.
Diet & Energy
Gilltail diets vary widely. One (the Wisker Gilltail) will even consume the eggs and young of other gilltails.
Evolution
Locomotion
Gillworms swim through the water by moving their bodies in a side to side waving motion.
