Prey detection by great cormorant (Phalacrocorax carbo sinensis)in clear and in turbid water [PDF]

Journal of Experimental Biology, 2008
SUMMARYThe scattering and absorption of light by water molecules and by suspended and dissolved matter (turbidity) degrade image transmission and, thus,underwater perception. We tested the effects on visual detection of prey size and distance (affecting apparent prey size) and of low-level water turbidity in hand-reared great cormorants (Phalacrocorax ...
