Short description. A cervical sinus is evident between the head and the body. The head is small and round in shape, with a pointed rostrum and pigmented patch of ocellus. The head shield is present. The antennules are fused with the ventral portion of the head. Fine ciliation is present at the postabdominal claws. The morphological characteristics concur with the descriptions and illustrations provided by Petersen and Carlos (1984), Berner (1985), Fernando (1992) and Dumont and Negrea (2002).

Ecological distribution. Ceriodaphnia cornuta is present in lakes and a reservoir. This species is a primary grazer in the freshwater habitats and has a great competitive power against with larger grazers ( Rizo et al. 2017).
