Epaulette Shark life on the Great Barrier Reef

Epaulette Shark

  • 🦈 The Shark That “Walks”. The Epaulette Shark is famous for its ability to “walk” along the ocean floor using its strong pectoral and pelvic fins, making it one of the most unique sharks in the world.

  • 🌊 Found on the Great Barrier Reef.  This fascinating shark thrives in the Great Barrier Reef’s shallow coral reefs and tidal pools, often spotted around Heron Island, Lady Elliot Island, and other outer reef locations.

  • 😴 Survives in Low Oxygen Environments. – The Epaulette Shark can slow its heart rate and oxygen consumption, allowing it to survive in rock pools and areas with little water movement, even at low tide.

  • 🎨 Recognizable by Its “Epaulettes” . Named after the large black spots behind each pectoral fin, which resemble military epaulettes, these markings help to deter predators by mimicking large eyes.

  • 🏖️ Can Survive Briefly Out of Water. Thanks to its unique adaptations, the Epaulette Shark can withstand short periods out of water, making it well-suited for life in tidal reef environments.

  • 🐠 Harmless to Humans.  Despite being a shark, the Epaulette Shark is small, non-aggressive, and completely harmless to humans, making it a fascinating species for snorkelers and divers to observe.

  • 🌙 Most Active at Night. Epaulette sharks are nocturnal hunters, feeding on small fish, crustaceans, and worms as they move slowly across the reef floor after dark.

Discover the epaulette shark

The Great Barrier Reef is home to many species, including the Epaulette shark. This small, unique shark species can “walk” on its fins and survive in low-oxygen environments.

Habitat and Distribution

A diminutive species that inhabits the shallow waters of the Great Barrier Reef, spans the Indo-Pacific region.

Appearance

This small, slender shark can grow up to three feet long. Its distinctive pattern of dark spots and stripes on its body helps it blend in with its surroundings. The epaulette shark has a long, slender tail, a flattened head, and a small mouth full of sharp teeth.

Behaviour

It is known for its ability to “walk” on its fins.
This is done by using its pectoral and pelvic fins to move along the seabed, which allows it to navigate through narrow crevices and shallow waters. It can also survive in low-oxygen environments by slowing its metabolism and using its gills more efficiently.

Conservation Status of the Epaulette Shark

The Epaulette Shark is currently listed as a species of Least Concern by the International Union for Conservation of Nature (IUCN). However, their populations are declining in some areas due to habitat loss and overfishing. Protecting their habitats and regulating fishing practices are important to ensure these unique sharks continue to thrive in the wild.

FAQs

What is an Epaulette Shark?

  The (Hemiscyllium ocellatum) is a small, reef-dwelling shark found in the shallow waters of the Great Barrier Reef. Known for its distinctive black “epaulette” spot behind each pectoral fin, this fascinating shark is famous for its ability to “walk” on the ocean floor using its fins.

Can Epaulette Sharks really walk?

Yes! Unlike most sharks, Epaulette Sharks use their pectoral and pelvic fins to “walk” across the reef floor. This adaptation allows them to move easily through rock pools, shallow coral lagoons, and sand flats, making them one of the most unique sharks in the world.

Are Epaulette sharks dangerous to humans?

They are not considered dangerous to humans. They are a small species of shark and cannot inflict serious harm.

Can I see Epaulette sharks while snorkelling or diving in the Great Barrier Reef?

Yes, both divers and snorkelers frequently see them on the Great Barrier Reef.

How do Epaulette Sharks survive in low oxygen environments?

They can survive in areas with very little oxygen, such as shallow rock pools at low tide. They can slow their heart rate and reduce oxygen use, allowing them to stay out of water for short periods—a survival trick that few other sharks can match!

Interesting Facts

  • This shark can survive for up to an hour out of the water by using its spiracles to extract oxygen from the air.
  • These sharks have small, pointed fins to walk across the reef for prey.
  • One of the few species that can survive in low-oxygen environments.
  • These sharks can lay eggs and produce offspring without needing a male to fertilise the eggs.

Conclusion

The epaulette shark is a unique and fascinating species in the Great Barrier Reef. By learning about their habitat, behaviour, and conservation status, we can help protect this species and ensure that future generations can continue to enjoy the beauty of the Great Barrier Reef.
