Ecology Summary - Crocodylus porosus

Language:

Ecology of Crocodylus porosus

Main Ref.	Greer, A.E., 2006
Remarks	Active throughout the year. Hunts by day and night; hunting probably associated to diving behavior. Size determines feeding, i.e., small crocodiles feed frequently on small prey items while larger crocodiles feed infrequently on larger prey. May consume carrion. Gastroliths (stomach stones) help in digesting food items.
