Five modes of foraging behaviour were observed and quantified (ending at fixate-orient; ending at approach and/or chase; ending at failed attack; ending at capture and loss; successful consumption). Each mode represented an increasingly progressive end-point from initial sighting of the prey to final consumption. Compared to controls., 0.5 μg l−1 Cd-exposed predators captured significantly fewer prey, while 5 μg l−1 Cd-exposed predators made fewer attacks. Both Cd-exposed groups consumed fewer prey than controls.
