Fish of the Atlantic Ocean
Fish are some of the most diverse and important animals in the Atlantic Ocean, living everywhere from shallow reefs to deep offshore waters. Discover fish species found in Atlantic waters and the habitats they rely on.
Atlantic Ocean Fish Species & Behavior
The Atlantic Ocean supports a wide range of fish species that depend on its coastal ecosystems, open-water feeding zones, and deep-sea environments. These fish are shaped by powerful currents, seasonal conditions, and the availability of food across different regions of the Atlantic.
Many Atlantic fish species migrate or shift their range throughout the year, moving between feeding grounds and warmer waters. Water temperature, ocean currents, and baitfish concentrations often influence where fish are found season to season.
Seasonal changes and ocean currents influence where whales travel throughout the year, making the Atlantic a vital migration corridor for many species.
Atlantic Bluefin Tuna
A powerful, fast predator, Atlantic bluefin tuna travel long distances across the Atlantic following seasonal feeding patterns.
Atlantic Cod
A well-known cold-water species, Atlantic cod are commonly found along continental shelves and cooler North Atlantic ecosystems.
Mahi-Mahi (Dolphinfish)
Brightly colored and fast-moving, mahi-mahi thrive in warm Atlantic waters and are often found near floating seaweed lines.
Stoplight Parrotfish
A reef fish known for grazing algae, parrotfish help support healthy reef systems in tropical Atlantic and Caribbean waters.
