Epaulette Shark

Overview

The epaulette shark is a slender, bottom-dwelling carpet shark recognized by the prominent, white-ringed black spots situated just behind its pectoral fins. These markings resemble military epaulettes, giving the species its common name. Well-adapted to dynamic coastal environments, this shark is famous for its unique ability to navigate across exposed reef flats during low tide.

Appearance

Adults feature a light brown or cream-colored body marked with scattered darker spots and indistinct saddles. They possess broad, paddle-shaped paired fins and an elongated tail structure that accounts for over half of their total length. Their bodies are flexible and slender, allowing them to maneuver easily through tight crevices in coral structures.

Biology & Behavior

This species is widely known as a "walking shark" because it uses its strong, rounded pectoral fins to crawl across shallow sea floors, coral heads, and even exposed land when trapped by receding tides. To cope with temporary isolation in shallow tide pools where oxygen levels plummet, the epaulette shark can drastically suppress non-essential metabolic and bodily functions, enabling it to survive periods of severe hypoxia.

Feeding

Active primarily around dusk and dawn, the epaulette shark hunts along the ocean floor and inside sediment. Its diet consists largely of small benthic invertebrates, including worms, crabs, and shrimp, alongside small reef fish. It frequently uses its flexible body and specialized mouth structure to probe and extract prey from hard-to-reach hiding spots.
