description Epaulette shark Overview
A large black spot with a pale border behind each pectoral fin gives the epaulette shark its name. This small carpet shark belongs to the family Hemiscylliidae and inhabits shallow reef and tidal waters around northern Australia and New Guinea. It grows to roughly 90 centimeters, with an elongated body suited to moving through the confined spaces and uneven surfaces of reef habitats. Its paired pectoral and pelvic fins can support a walking-like movement across reef flats and tide pools.
This does not make it a land animal, but it allows a form of locomotion quite different from the continuous swimming associated with many sharks. The species can also tolerate the low oxygen levels that develop in isolated pools at low tide. It suits readers interested in adaptations to changing coastal conditions, with its fin-assisted movement and tolerance of oxygen shortage setting it apart within familiar shark comparisons.
help Epaulette shark FAQ
How large do epaulette sharks grow?
Epaulette sharks are a small species of carpet shark, typically growing to a maximum length of about 90 centimeters. Their modest size makes them highly adaptable to the confined spaces of shallow coral reef environments.
Why is this shark called the 'epaulette' shark?
It is named for the large, distinctive black spots ringed with white located just behind its pectoral fins. These markings resemble the ornamental shoulder boards, or epaulettes, historically worn on military uniforms.
Where is the natural habitat of the epaulette shark?
This species is native to the shallow coral reefs and tidal pools off the northern coast of Australia and around New Guinea. They are uniquely adapted to survive in these extreme, low-oxygen environments during low tide.
Can the epaulette shark survive out of water?
Yes, the epaulette shark is famous for its ability to walk on its pectoral and pelvic fins across dry land. It can survive for extended periods out of water by slowing its heart rate and breathing, allowing it to travel between isolated tidal pools.
