Description and Classification

Haemulon flavolineatum, also called the French grunt, banana grunt, gold laced grunt, open-mouthed grunt, redmouth grunt, or yellow grunt, is a kind of marine ray-finned fish. It belongs to the grunt group and is part of the family Haemulidae.

Habitat

This fish lives in warm tropical and temperate waters from the southern Caribbean up to the southeast part of the U.S., in the western Atlantic Ocean.

Behavior and Role

These fish are known for their beautiful colors and patterns, making them popular among people who study or watch sea life. They usually live near coral reefs and rocky areas where they can find food and shelter. The French grunt helps keep the balance of its ocean home by eating small plants and animals, supporting other sea creatures.

Taxonomy

H. flavolineatum was first described in 1823 by a French zoologist named Anselme Gaëtan Desmarest. The name refers to the yellow lines on its body.

Distribution

The French grunt, also called the banana grunt, lives in the western Atlantic Ocean. You can find it from South Carolina and Bermuda down the coast of the United States to the Bahamas. It also lives in the southern Gulf of Mexico, including the Florida Keys. Its range stretches from Tuxpan in Mexico along the northern coast of the Yucatan Peninsula to northwestern Cuba, and further south into the Caribbean Sea as far as Trinidad.

Description

The French grunt, H. flavolineatum, has an almond-shaped body that ends in a blunt snout. It has a small to medium-sized mouth with thick lips and teeth in narrow bands on each jaw. Its dorsal fin has a small notch and contains 12 spines and 14-15 soft rays, while the anal fin has 3 spines and 8 soft rays.

This fish is usually whitish, bluish, or yellowish. It has three bright yellow to orange horizontal stripes above the lateral line and several similar stripes below it. The lower part of its head has yellow spots, and its mouth's inside is red. Its fins are yellow, and its belly is white. While it can grow up to 30 cm (12 in), a more common size is around 17 cm (6.7 in).

Habitat and biology

The French grunt, H. flavolineatum, lives in shallow waters from 1 to 60 meters deep. It prefers rocky areas and coral reefs, often hiding under ledges or near elkhorn coral. Young grunts stay in groups in sea grass beds in calm bays and coastal waters. These fish are mostly active at night, searching the ocean floor for food such as molluscs, crustaceans, and polychaetes. Their eggs and baby fish float in the water for about two weeks before settling in the sea grass.

Parasites

The French grunt has several known parasites, including a small crustacean called Gnathia marleyi. This parasite is named after the reggae singer Bob Marley.

Human uses

The French grunt, or H. flavolineatum, is a common fish in its area. People catch it using traps and seines. The fish are usually sold fresh. Near Barbados, this fish is often caught for fishing. It is not often found in small aquariums, but you can see it in large public displays like a public aquarium.
