cercaria defined in 1951 yearcercaria - cercaria;
cercaria - One of the larval forms of flukes (Trematoda); produced asexually by redia larvae while these are parasitic in snails. Cercariae are infective to a new host to which they gain access either in food (sheep liver-fluke) or by penetrating skin (Schistosoma). This new host may be the definitive one, in which the cercariae become sexually mature flukes; or in some species it may be a second intermediate host, where they live for some time before being swallowed by definitive host and becoming sexually mature.
