The white grunt is a medium-sized fish, about 12 inches long, with a maximum length of around 20 inches. It has an oblong body that is silver-white with numerous fine horizontal yellow stripes. Its pelvic, dorsal, anal, and caudal fins are all entirely yellow.

The white grunt prefers steep drop-offs or rocky overhangs
A series of blue horizontal stripes runs across the head of the white grunt, alternating with the yellow stripes.
Range
The white grunt is commonly found in the Caribbean sea, the Gulf of Mexico and along the coasts of Florida. It inhabits the tropical waters of the western Atlantic, from Florida in the north to the coasts of Brazil in the south, including many Caribbean islands such as the Bahamas and
Guadeloupe.
Habitat
The white grunt typically lives in shallow waters, from the surface down to about 130 feet. It forms schools of varying but dense sizes around coral reefs, along rocky substrates or above sandy bottoms. The white grunt does not travel extensively with the seasons or throughout its life and generally stays in the same area.
Diet
The white grunt is a carnivorous fish that primarily feeds at night on a variety of small bottom-dwelling invertebrates like shrimp, as well as smaller fish.
Besides recreational and commercial fishing, the white grunt is often preyed upon by larger fish such as snappers, groupers and sharks.
Reproduction
The white grunt reproduces sexually. Across its range, the spawning period extends nearly throughout the year, with a peak activity lasting two months but occurring at different times depending on the geographic location.
