Sharks are integral to healthy reef ecosystems. The Red Sea maintains robust shark populations that indicate ecological health and underscore the region’s conservation success. Shark Species of the Red Sea Blacktip Reef Sharks: Common at depths of 3-20 metres. Named…
The Coral Triangle contains more fish species than any other region on Earth—over 3,000 species, with 40% found nowhere else. This extraordinary concentration of endemism reflects millions of years of isolated evolutionary development. Speciation and Endemism Endemism occurs when geographic…
The Coral Triangle harbours some of Earth’s most sophisticated cephalopods—octopuses, cuttlefish, and squid. These molluscs represent a separate evolutionary line of intelligence, with nervous systems fundamentally different from vertebrates yet displaying comparable problem-solving abilities. Masters of Camouflage and Cognition Cephalopods…
The humpback whales that pass through the waters off Bundaberg every winter are not on their way to somewhere more interesting. This is the destination – the shallow, warm waters of the southern Great Barrier Reef, where females come to…
Nudibranchs are sea slugs - which sounds unpromising until you see one. The Great Barrier Reef hosts over 600 species, and each one is a small masterpiece of colour and form.
Wobbegongs are the reef's most overlooked sharks - flattened, patterned, and so perfectly camouflaged that divers swim over them constantly without noticing. Which is exactly how the wobbegong likes it.
Cephalopods are the reef's most intelligent invertebrates - and possibly its most intelligent animals, full stop. Watching a cuttlefish change colour in real time is one of the reef's most extraordinary experiences.
My dive guide — a small, sun-weathered woman named Rosa who had been diving the reefs off Tulamben in Bali for twenty years — once told me that she could spend an entire dive on a patch of rubble no…
Six of the world's seven sea turtle species are found on the Great Barrier Reef. They've been navigating these waters for 100 million years - and they're in more trouble now than at any point in that history.
Scorpionfish are the reef's most dangerous fish to step on, and lionfish are among its most spectacular. Both are masters of the same strategy: look like something that isn't a fish, then strike.
