Blind eels can live parasites in large fish because of its special texture. Blind salaries are like freshwater eels, but the head has no jaws on the lower jaw, the mouth is just a suction piece that grows sharp horn teeth. Its bearing is in the form of a pocket, the inner hole is connected directly to the throat, the outer hole is far away from the mouth behind the flare, causing its front body to penetrate deep into the fish's abdomen, without affecting breathing. Blind eels rely on the suction mouth to cling to the fish, then find the opportunity to slip into the fish. Because the blind eel lives long in the fish's abdomen, the eyes are degenerated under the skin. The sense of smell and its 4 pairs of tentacles are very sharp, noticing the prey approaching immediately.

Blind eels belong to round mouth animals (Cyclostomata), bisexual, when mating, they make males first, then later become females. After fertilization, not through metamorphosis, directly laying eel.
