Geleiidae
Geleiidae is a family of karyorelict ciliates. It is sometimes synonymized with family Aveliidae.
Geleiidae are very large ciliates, with a cylindrical shape, and a thinner, often beak-shaped, apical region. They are characterized by a ventral oral region, with buccal infraciliature organized into one intrabuccal kinety and an extrabuccal row.
The family name is based on Geleia, the type genus.
