Live coral predation by fish was evaluated in two bays of the Tayrona National Natural Park (Colombia), as a possible biological agent causing mortality. Visual censuses were used to identify most important predator. Predation incidence determined examining all colonies present permanent belt transects (20 x 2 m) reef environments (one dominated Colpophyllia natans and other one Montastraea faveolata), for climatic seasons (rainy dry seasons). The parrotfish Sparisoma viride predator due its biting frequency bite size. S. adults initial terminal phases, removed live tissue part calcareous matrix M. faveolata, annularis, Porites astreoides C. natans, which, last lost major amount per area (3.51 cm2) volume (3.22 cm3) bite. A negative exponential tendency (r2=0.94), between density found, indicating that determines bite’s damage. There is no clear relationship at sites studied. At Chengue Gayraca bays, factors contributing loss could have consequences on dynamic these reefs
