Diet A benthic predator that feeds on crabs, shrimp, small bony fish, and polychaete worms. They use their sense of smell and electroreception to find prey hiding in the sand or reef crevices.

Behavior

The Epaulette Shark is a master of the shallow reef, famous for its extraordinary ability to 'walk' across the seabed and even over dry land. Unlike most sharks that must swim to breathe, this species uses its muscular pectoral and pelvic fins to crawl through tide pools and across coral flats. This adaptation allows them to navigate extremely shallow waters where larger predators cannot follow, often being found in water only a few inches deep.

These sharks are remarkably hardy and have evolved to survive in low-oxygen environments. During low tide, when oxygen levels in tide pools can plummet, the Epaulette Shark can slow its heart rate and shut down non-essential brain functions to survive for up to an hour without oxygen. They are generally solitary and non-aggressive toward humans, often remaining perfectly still if approached, relying on their camouflage to blend into the reef floor.

Camera Tips

Capturing the Epaulette Shark requires an underwater setup, specifically targeting the 'intertidal zone' where the reef meets the shore. If you live near a reef flat, place your camera in a permanent tide pool that remains submerged during low tide but stays relatively shallow (1-3 feet deep). Use a weighted mount or a tripod secured with dive weights to prevent the camera from shifting with the tide's surge. Angle the camera slightly downward toward sandy patches adjacent to coral heads, as these are the shark's primary hunting grounds.

Because Epaulette Sharks are primarily nocturnal, your camera must have strong infrared (IR) capabilities or be paired with a motion-activated red light. Sharks can be sensitive to bright white light, which may cause them to flee, but red light is often less intrusive for benthic species. Set your camera to record video bursts of 20-30 seconds; watching their 'walking' gait is far more rewarding than a still image and helps confirm the species identification.

To increase your chances of a close-up, you can place a perforated PVC 'scent tube' containing oily fish (like sardines) just inside the camera's field of view. The shark's keen sense of smell will lead it to investigate the source. Since these sharks are most active during low tide at night, check the local tide charts and ensure your camera is positioned in a spot that won't be completely dry, but where the water is calm enough to avoid 'bubbles' or debris clouding the lens. High-frame-rate settings are less important here than low-light sensitivity, as their movement is slow and deliberate.

Similar Species

Generally lacks spots as an adult and has a thicker body, without the specialized 'walking' fin structure.

Frequently Asked Questions

Yes, the Epaulette Shark can 'walk' across dry land or exposed coral for short distances during low tide. They use their strong, paddle-shaped fins to crawl between tide pools when searching for food or escaping areas with poor water quality.

No, they are completely harmless to humans. They have very small teeth designed for crushing shells and are generally quite docile. They are more likely to hide or stay still than to interact with people.

Using a scent lure is the most effective method. Place a small amount of crushed shellfish or oily fish in a mesh bag or a secured container with holes near your camera. The shark's acute sense of smell will draw it to the area even in total darkness.

They are most commonly found in the shallow coral reefs of the Great Barrier Reef and other northern Australian waters. Look for them in tide pools, reef flats, and seagrass beds at depths of less than 130 feet, though they are often in just inches of water.

The easiest way to identify an Epaulette Shark is by the large black spot with a white ring located just behind each pectoral fin. If you see it 'walking' on its fins rather than swimming, it is almost certainly a member of the Hemiscyllium genus.
