Species Overview

Atlantic Halibut

The Atlantic halibut is the largest flatfish in the world, capable of exceeding 300 kg. Both eyes are on the right side of its body. It is a slow-growing, long-lived species that has suffered severe overfishing.

Summer Flounder

The summer flounder, or fluke, is a flatfish that lies camouflaged on the ocean floor. Born with eyes on both sides, one eye migrates to the left side during development. An ambush predator, it explodes upward to grab passing prey.
