Species Overview

Atlantic Bluefin Tuna

The Atlantic bluefin tuna is one of the largest bony fish, capable of crossing the Atlantic in under 60 days. A single specimen has sold for over $3 million at Tokyo's fish market. It can maintain a body temperature above the surrounding water.

Goliath Grouper

The goliath grouper is the largest grouper in the Atlantic Ocean. This massive reef dweller can swallow prey whole and produces a distinctive booming sound by contracting its swim bladder to ward off intruders.
