Parrotfish On The Great Barrier Reef

Updated Wed 26 Jun 2024

Parrotfish in the Great Barrier Reef have distinct features that make them stand out. Their name was derived from their bright colours and mouth that resembles a bird’s beak. However, there’s no one species of this specific animal that looks like another. Parrotfish have made the Great Barrier Reef their home, and divers can easily spot one while snorkeling or scuba diving. Their population is widespread and you’re likely to see them munching on coral in any of the local reef sites near Cairns!

Parrotfish Reef Value and Contribution to Ecosystem

Parrotfish contribute to the coral reef ecosystems because they consume a lot of algae, which usually grows inside coral polyps. Parrotfish need to rip chunks of coral so they can reach the algae. It became a misconception that parrotfish damage coral reefs. However, according to recent studies, they actually help bleached coral recover because they eat the algae that stops new coral growth. It’s just fascinating to know that these colorful creatures provide value to the reef’s ecosystem!

Interesting Parrotfish Facts

Curious to know more about the parrotfish that live on the Great Barrier Reef? We’ve got you covered. Here are some more fun facts about these beautiful fish. 

Parrotfish Swap Genders

This might sound weird, but parrotfish change sex as they grow. They usually swap from female to male. As female parrotfish grow bigger, they change into males and challenge other males for the leadership of their group. This is called “protogynous hermaphroditism.” When the process takes place, the color of the parrotfish also drastically changes.

Parrotfish Have Extremely Hard Teeth

The parrotfish makes good use of its hard and strong teeth. They utilize it to chew on coral, and it works effectively because their teeth are fused with their jawbone. Their teeth’s structure is considered stronger than copper, silver, and gold. 

Parrotfish Utilize the Full Moon for Mating

Hundreds of parrotfish use the full moon’s light and go through a process called “lek mating.” The males bash their heads together as a sign of defending their territories while the females put on a parade. They spawn sperm and eggs into the water afterward, and the fertilization process takes place. 

Parrotfish Create Mucus Sleeping Bags

Some parrotfish species create a transparent cocoon composed of secreted mucus that comes from special glands. They do this before sleeping at night. It helps protect them from parasitic isopods while they sleep. The smell of this mucus also helps mask them from predators such as sharks and eels.
