Shark ecosystem
Sharks are one of Nature’s incredible success stories. Having lived on the Earth for approximately 450 million years, they’ve survived five of Earth’s major extinctions which wiped out between 75% and 96% of life. It’s only now, in the past ~100 years, have sharks faced the threat of extinction.
Healthy oceans need sharks. Sharks are considered ‘keystone’ species meaning that without them, the ecosystems around them could become unstable and face possible collapse.
Sharks typically occupy the top of the food chain and not only keep numbers in check through predation, but also because of how they affect the behaviour of other animals in an ecosystem.
For example, the presence of a cruising Tiger Shark is enough to keep dugongs on alert and limit the amount of time they spend eating seagrass. What’s even more amazing, is that Tiger Sharks are helping us combat climate change by protecting seagrass, a key carbon store of the oceans.
Without sharks, the Great Barrier Reef and other incredible marine habitats in Australia will likely face irreparable change. Sharks are needed for the ocean’s survival, and ultimately ours.
Australia is a shark and ray hotspot with one quarter of their known species found in Australian waters. Half of Australia’s 322 shark and ray species are endemic - they’re found nowhere else in the world.

Ecosystem partnerships
Sharks and rays love a beauty treatment. Manta Rays, Reef Sharks and Hammerheads visit ‘cleaning stations’ in the Great Barrier Reef where fish called Cleaner Wrasse pick off scraps and parasites from the gills and teeth of their ‘client’ .
Unique & essential
Shark and ray species exhibit unique qualities that ensure balance and species diversity is maintained within the marine ecosystem.
For example, the Epaulette Shark of the Great Barrier Reef uses its fins to ‘walk’ across exposed reefs going from rockpool to rockpool to find food.
Australia’s sharks are record breakers. There’s a lot to appreciate for the role and ability shark and ray species bring to the marine ecosystem.
The Whale Shark is the world’s largest fish measuring up to 12 m, the Shortfin Mako is the world’s fastest shark clocking up speeds of up to 74 km/h, and a Great White Shark called ‘Nicole’ holds the record for the fastest long-distance travel by a shark – a return trip of over 20,000 km to Australia from South Africa in just 9 months.
