Life History

Although highly migratory confirmed to travel thousands of kilometers there are only two definite spawning locations. The Gulf of Mexico and the Mediterranean Sea in the Eastern Atlantic. Little is known why they spawn there, although favorable environmental factors are likely the reason. In the Gulf of Mexico spawning occurs from Mid-April to Mid-June. In the Eastern Atlantic spawning occurs exclusively in the Mediterranean and Adriatic Sea from June to August.
