Today's Research for Tomorrow's Oceans

Species Type:


Common Name(s):



The average weight of a cobia is 50 pounds (23 kilograms). On average, they reach lengths of 20-47 inches (50-120 centimeters).


Cobia eat eels, mullet, snappers, grunts, pinfish, grunts, croakers, and their favorite, crabs.

Range & Habitat:

Cobia can be found along continental shelves and offshore reefs in the Atlantic Ocean, the Indo-West Pacific and throughout the Gulf of Mexico. They can also be found more inshore inhabiting bays, mangroves and small inlets.


Cobia are highly adaptable fish, able to survive in environments with low oxygen and high water temperatures. Fairly anti-social, cobia like to travel alone or in small groups. From June to late August, cobia will spawn in nearby bays and estuaries, releasing anywhere from 375,00 to 2 million eggs each time they spawn. According to the International Union for Conservation of Nature’s Red List of Threatened species, cobia are considered Least Concern.
