cercariae's Usage Examples:

sporocyst in which secondary sporocysts are formed and give rise to cercariae later on.

The cercariae are released from the snail to form metacercariae and the life.

females, require a nutrient source in order to properly develop from cercariae to adults.

go through several developmental stages inside the snail: sporocysts and rediae, with the latter giving rise to many cercariae, which emerge from the snail.

sporocysts, then rediae, and finally emerge from the snail as cercariae.

For example, some species of Planorbella host rediae and cercariae stages of the parasite Ribeiroia, prior to ultimate infection.

rediae, either of which may give rise to free-swimming, motile cercariae larvae.

The cercariae then could either infect a vertebrate host or a second intermediate.

It was first described in 1956 by Martin, who had found cercariae (a larval stage of a fluke) released by the snail Cerithidea californica.

intermediate host into a sac-like structure known as a sporocyst or into rediae, either of which may give rise to free-swimming, motile cercariae larvae.

intermediate host, a crustacean such as a crab or crayfish, where they encyst and become metacercariae.

The crawling cercariae penetrate fresh water crabs and encyst in its muscles becoming metacercaria.
