Australia’s Great Barrier Reef is home to an abundance of sea life

Recognised as a wonder of the modern world and a famous World Heritage Site.

There is a higher density of marine life in some of the reefs, than in all of the Caribbean Ocean.

With more than 1500 species of Great Barrier Reef fish, the water is teeming with activity and beauty.

The fish of the Great Barrier Reef are incredibly diverse, and you’ll even find rare marine life, whales, dolphins and much more.

The Great Barrier Reef marine life is the highlight of any trip to the reef system, as well as the vibrant hard and soft corals.

At the Great Barrier Reef, you’ll see red bass, which is the oldest living fish in the reef with a lifespan of 50 years.

You’ll also see the biggest fish in the reef, the whale shark. Coral trout is a fish that you’ll find at the reef as they change sex as they grow and live up to 16 years!

In addition to the fish of the Great Barrier Reef, you’ll also discover six of the seven species of sea turtles.

You’ll even see the largest sea turtle, the Leatherback.

If you’re lucky, you’ll see the sea turtles lay their eggs on the shore.

The Great Barrier Reef’s marine life also includes 30 species of dolphins, whales and porpoises. One of the most frequent visitors to the reef are the Dwarf Minke whales, but you’ll also see Humpback whales, which are the fifth largest animal in the world.

You’ll see a variety of dolphins, including Indo-pacific humpback dolphins and Irrawaddy dolphins.

The Great Barrier Reef also has the largest population of dugongs, which are closely related to elephants; although, they look more like whales and dolphins.

Fourteen species of sea snakes also call the Great Barrier Reef home, as well as 5000 species of molluscs, which includes giant clams, cone shells and nudibranchs.

You’ll also spot a few octopus, cuttlefish and squid.

Of course, the Great Barrier Reef fish aren’t the only reason the reef system is among the most highly sought scuba diving destination.

The hard and soft coral formations are a top attraction, too, which are living animals.

The Great Barrier Reef’s marine life is spectacular in itself, offering ample opportunities to witness nature at its finest.


The breathtaking and colourful collection of Great Barrier Reef animals offer an unforgettable experience that won’t be matched anywhere else in the world.

The very best way to see the Great Barrier Reef marine life is on a liveaboard tour.
