The Marbled shark is also known as the Coral catshark. The eyes are set in front of large spiracles, which are used to move water into the gill chambers when the shark is at rest or feeding. The name comes from the cat-like shape and the color of the eyes.
They are commonly seen on shallow reefs in temperate and tropical waters. They range in Pakistan to New Guinea, Philippines, China and southern Japan. They live among coral branches and in the holes and tight crevices of the reef.
They are nocturnal and feed on bottom dwelling invertebrates and small fish that they find using their electroreceptors and sense of smell.
This species is oviviparous. The female coral catshark lay purse-shaped egg cases, usually two at a time, with tendrils to anchor the cases to the bottom. The pups are about 4 inches long at birth, and are rarely encountered as they spend their time sequestered within the reef, out of the way of predators.
Larger fish and sharks are known predators of the marbled shark.
