Interpopulation and context-related differences in responses of a marine gastropod to predation risk
Article Abstract:
Whelks sympatric with the asteroid L. polaris show escape responses more readily in the presence of this predator than do whelks allopatric with L. polaris. It has been established that whelks sympatric with the lobster H. americanus hide in the sediments and retreat into their shell when they become aware of the presence of a lobster more readily than is the case with whelks allpatric with H. americanus. It seems that whelks adjust their defensive responses to the threat represented by predatory lobsters and asteroids.

A transmissible trematode affects the direction and rhythm of movement in a marine gastropod
Article Abstract:
A new study examines the effect of the trematode fluke Microphallus piriformes on the behavior of its intermediate host, the periwinkle Littorina saxatalis, during the breeding cycle of the periwinkle's main predator, the herring gull. The study finds that the parasite induces changes in the periwinkle's direction and rhythm of movement that increases the chance of predation by gulls. This could be an important survival strategy by the trematode.
