Iconic Animals of the Great Deck: A Guide to the Great Barrier Reef’s Marine Life

1. Coral

The foundation of the reef, coral, is not just one organism but a collection of tiny living creatures called polyps that build calcium carbonate homes around their bodies. These structures form the vast and colourful coral reefs that provide habitat for many other marine species.

2. Fish

Home to over 1,500 species of fish, the reef’s waters shimmer with life. From the iconic clownfish, sheltering in anemones, to the majestic maori wrasse, and the tiny but vibrant damselfish, each species plays a role in the reef’s ecological balance.

3. Sharks and Rays

The reef provides sanctuary to various sharks and rays, including the gentle reef shark, the sleek blacktip shark, and the impressive manta ray. These predators are crucial for maintaining the health of marine ecosystems by keeping other fish populations in check.

4. Marine Turtles

Six of the world’s seven species of marine turtles, including the green turtle and the hawksbill turtle, can be found on the Great Barrier Reef. These ancient mariners use the reef as feeding grounds and nesting sites, and it is a popular sight on many tours.

5. Marine Mammals

Dolphins and whales frequently visit the reef. The playful bottlenose dolphin can often be seen frolicking in the waters, while the majestic humpback whale migrates through the reef area, offering spectacular sightings during the winter months.

6. Sea Birds

The islands and cays of the Great Barrier Reef also provide critical nesting sites for a vast array of seabirds, including the white-bellied sea eagle and the roseate tern. These birds depend on the reef for food and nesting sites.

7. Invertebrates

The reef’s biodiversity includes an astounding variety of invertebrates. Colourful sea slugs, octopuses, starfish, and giant clams are just a few species that add to the reef’s vibrant life.

8. Sponges and Anemones

These often overlooked reef residents play essential roles in the ecosystem. Sponges filter the water, removing impurities, while anemones provide homes to clownfish and other species, offering protection in exchange for food scraps.
