The Ocyurus chrysurus, commonly known as the Yellowtail Snapper, is a vibrant fish native to the western Atlantic Ocean. Recognizable by its striking yellow stripe and tail, it inhabits coral reefs and sandy seabeds. This species is agile and social, often forming large schools.

Ocyurus chrysurus, commonly known as the Yellowtail Snapper, is native to the western Atlantic Ocean. Its geographical distribution includes the coastal regions of the southeastern United States, the Bahamas, the Gulf of Mexico, the Caribbean Sea, and as far south as Brazil. It is prevalent in the waters surrounding the Florida Keys, Cuba, and other islands in the Caribbean.

Yellowtail Snapper typically inhabit warm, tropical marine environments. They are commonly found in coral reef ecosystems, rocky bottoms, and seagrass beds, where they can access both shelter and food resources. They prefer clear waters with a moderate to high salinity level and are often found at depths ranging from 10 to 70 meters (approximately 33 to 230 feet).

Ocyurus chrysurus plays a significant role in the coral reef ecosystem as both predator and prey. As a mid-level predator, it feeds on smaller fish, crustaceans, and cephalopods, contributing to the control of these populations. In turn, Yellowtail Snapper are preyed upon by larger fish species, sharks, and humans. They are known for their schooling behavior, which provides some protection against predators and facilitates efficient foraging.
