**Euhaplorchis Californiensis**
= = = =

Description

 * a tropically transmitted parasite (TTP) modifies behavior of the prey to increase the likelihood of its transmission to the next host, the predator.


 * Habitat**
 * lives in the salt-water marshes of Southern California

In the Horn-snails = =
 * the eggs of //E. californiensis// consumed by horn snails
 * while living inside a snail after hatching, //E. californiensis// will inhibit the snail’s fertility sometimes for several generations
 * the cercariae (the disk-shaped larva having a tail-like appendage) swim out into the marsh

In the Killifish
 * the cercariae surrounds the fish’s brain and causes it to swim near the surface and wiggle around making the fish more likely to be eaten by a bird
 * infected killifish are 4 times more likely to “shimmy, jerk, flash, and surface” than uninfected fish

In the Shore birds
 * this bird eats the killifish along with the worm
 * the worm lays its eggs in the digestive system of the bird
 * the eggs are excreted onto the beach where snails can feed on

= =


 * Impact **
 * it has been estimated that without E. californiensis, the population of horn-snails would be doubled
