Blepharisma

Blepharisma is a genus of heterotrich ciliates (a type of protista) which contains many species. Its members are elongated and roughly egg-shaped, with a contractile vacuole without collecting channels. Typically, they are pigmented with some shade of red or pink. The anterior pole is pointed, the posterior pole is blunted. The body is noncontractile, but exact form may vary within one species and even within the same culture.
