Species Overview

Grand requin marteau

The great hammerhead is the largest of the nine hammerhead shark species. Its distinctive cephalofoil (hammer-shaped head) houses an array of electroreceptors that allow it to detect stingrays buried beneath the sand.

Cardeau d'été

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.
