Sharks that eat sharks: opportunistic predation by wobbegongs

Abstract

[Extract] Wobbegong sharks (family Orectolobidae) are demersal ambush predators of benthic invertebrates, cephalopods, teleost fishes, and, in larger species, occasionally other sharks (Compagno 2001; Huveneers et al. 2007). Field observations of predation events are rare on coral reefs, and trophic status is usually assigned using stomach content data from collected specimens (Huveneers et al. 2007).
