Seisonidae is a family of rotifers, found on the gills of Nebalia, a marine crustacean. Peculiar among rotifers, males and females are both present and equal in size. It is considered to have diverged from the other rotifers early on, and in one treatment is placed in a separate class Seisonoidea.[1]
[edit] Species
Two genera with total three species belong to Seisonidae[2]:
- Paraseison Plate, 1887

- Seison Grube, 1861
- Seison nebaliae Grube, 1861 – commensal of Nebalia[2]
