Crypsis and Behaviour in Sandhoppers: Antipredator Effectiveness in the Water


Dipartimento di Biologia Animale e Genetica, Università di Firenze, Via Romana 17, 50125 Firenze, Italy.


Predation experiments in tanks with the two-banded bream fish Diplodus vulgaris and the sandhopper Talitrus saltator demonstrated that: 1. some specific behaviours; and 2. crypsis of the back have an antipredator function. They reduced by one-half the predatory attacks in the water, under artificial conditions.
