Predatory Behavior and Prey Selectivity of the Pelagic Water Mite Piona constricta
Predation by the pelagic water mite Piona constricta on the various components of the zooplankton community of Heney Lake, Quebec, Canada, was investigated through both direct observation and several series of feeding experiments. On encountering a prey item, the mite seized the organism with its fo...

Predation by the pelagic water mite Piona constricta on the various components of the zooplankton community of Heney Lake, Quebec, Canada, was investigated through both direct observation and several series of feeding experiments.

The soft body tissues of the prey were predigested and the liquid nutriment was then drawn into the mouth.
