Epaulette Shark - Biology and Ecology - Feeding

Feeding

The epaulette shark is an opportunistic predator of benthic crustaceans, worms, and small bony fishes. Off Heron Island, over 90% of the epaulette shark's diet consists of polychaete worms and crabs, with juveniles taking mostly the former and adults mostly the latter. It hunts most actively at dawn and dusk, though feeding can occur at any time during the day. This shark relies mainly on its olfactory and electroreceptive senses to locate hidden prey. It is capable of sucking prey into its mouth by expanding its muscular buccal cavity. While searching for food, the epaulette shark sometimes turns over debris with its snout or thrusts its head into the sand, swallowing food items while expelling the sand grains through its gill slits. Unlike most sharks, the epaulette shark may chew its food for up to 5–10 minutes. Its teeth can be depressed to form a flat surface for crushing hard-shelled prey.
