Rachycentron canadum, commonly known as the cobia, is a large marine fish known for its elongated body, distinct dark lateral stripes, and strong swimming capabilities. Found in warm-temperate to tropical waters, cobia are known for their solitary behavior or small group formations. They feed on crustaceans and smaller fish, playing a crucial role in the marine food web.

Rachycentron canadum, commonly known as Cobia, is native to the tropical and subtropical regions of the world's oceans. It is primarily found in the Atlantic Ocean, including the western Atlantic from Massachusetts, USA, to Argentina, and the eastern Atlantic from Mauritania to Angola. It is also found in the Indo-Pacific, from the Indian Ocean to the western Pacific Ocean, including areas from South Africa to Japan and Australia.

Cobia typically inhabit warm coastal waters, often near structures such as reefs, wrecks, and buoys. They prefer water temperatures ranging from 20°C to 30°C (68°F to 86°F). These fish are often found in both inshore and offshore waters, indicating a preference for a variety of marine environments.

Cobia are pelagic and migratory fish that occupy the middle to upper levels of the water column. They are known for their opportunistic feeding behavior, preying on a wide range of organisms including crustaceans, small fish, and cephalopods. Cobia play a role as both predator and prey within their ecosystem, contributing to the balance of marine food webs.
