They belong to a group of sharks known as the Carpetsharks, which include wobbegongs and the Whale Shark. This species feeds on a wide range of small benthic invertebrates and bony fishes. [16] The epaulette shark is able to lower this energy demand further by reducing the metabolism of certain areas of its brain, e.g. keeping the sensory nuclei functional while deactivating the motor nuclei. Epaulette sharks are oviparous, with females depositing pairs of egg capsules around every 14 days from August to December. These sharks are found in shallow water habitat to a maximum depth of 50m.
