Animal Update: Smallmouth Grunts

Four smallmouth grunts were recently added to Atlantic Coral Reef!

Published February 23, 2018

The smallmouth grunt is a species of small fish found in the western Atlantic Ocean, from southern Florida to Brazil, including the Gulf of Mexico and the Caribbean Sea. They inhabit rocky shores and open areas of coral reefs in shallow waters.


This species has a thin body with a forked tailfin, silver coloration and five yellow, horizontal lines on its sides. Smallmouth grunts can grow to be up to 9 inches, but typically only grow to be around 6.5 inches.  

Smallmouth grunts spend a lot of time in schools, particularly during the day. At night, they feed on their prey, which includes plankton, small crustaceans and mollusks.  

There are various species of grunt fish, which are named for the sound they produce when grinding their teeth together. Smallmouth grunts have the smallest mouths of all grunt fish species.   

Stay tuned for more behind-the-scenes updates!
