| Abstract |
|
Since 1985 the biology and behavior of Phrynops hilarii (Duméril & Bibron, 1835) at São Paulo Zoo is being studied. Feeding behavior is divided in five phases (foraging, approach, capture, dilaceration and ingestion), but not necessarily all of them happen. During phase 1 the food or prey seems to be visually located. During phase 2 the food itens and stationaty preys are approached and examined by olfaction. Moving preys are pursued and there is no olfactory examination. During phase 3 the food is captured by suction. When food is bigger than turtle mouth it is dilacerated by one or both forefeet used alternately (phase 4). Ingestion is accomplished by gradual suction (phase 5). Intra and inter-specific cleptoparasitism was observed. Success in capture and ingestion of food seems not be dependent on species or size of the turtle. Adults, young, and hatchlings of P. hilarii are primarily carnivorous and vegetables were rarely eaten.
