Detection of prey by Calanus pacificus: implications of the first antennae

OSTI ID:5211467

Calanus pacificus, normally regarded as a passive filter-feeding copepod, displays active predatory behavior when fed with copepod nauplii. Larger nauplii are selectively preyed upon, even though they are better able to avoid capture than small nauplii. The involvement of the first antennae in the remote detection of motile prey is suggested by the experimental result that amputation of the antennae sharply reduces predatory feeding rates without affecting filter feeding.
