Bi-color parrotfish in Blacktip Reef

Did you know? Bi-color parrotfish sleep in bubbles of slime. Before finding their sleeping spot within the reef for the night, the parrotfish spins a cocoon around its body. The slimy bubble protects the parrotfish from nighttime predators by hiding its scent!

Parrotfish get their name from their beak-like teeth and bright coloration. They use their “beaks” to eat the algae that grows on and around coral.

When the coral rock has travel through the parrotfish’s digestive system (which extracts the needed nutrients from the algae), it comes out as sand! A large bi-color parrotfish can produce up to 2,200 pounds of sand per year!

This species is found throughout the warm waters of the Pacific and Indian Oceans.

Bicolor Parrotfish

We have a new bicolor parrotfish in our American Samoa exhibit!

Did you know? Before going to sleep, this species of parrotfish spins a cocoon around its body to hide its scent from potential predators!

Parrotfish get their name from their beak-like teeth and vibrant coloration. Some species, like the bicolor parrotfish, can grow to be up to three feet in length!

They use their “beak” to eat the algae that grows on coral. The parrotfish bites off pieces of coral from the reef, pulverizing it in order to digest the algae growing inside and then excreting the limestone rock. Much of the sand in the areas where parrotfish are found is actually the coral they excrete.

This fun little video explains this “sand making” process:

New Parrotfish

Eight princess, striped, and redband parrotfish have been added to our Atlantic Coral Reef exhibit.

Parrotfish have fused teeth that resemble a bird’s beak—hence their name. The teeth are specialized for scraping algae and invertebrates from coral and rocks. Another set of teeth (pharyngeal teeth) are on the floor and roof of the parrotfishes’ throats. These crush the ingested material.

 

Check out those chompers!
