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.

Sandre

The zander is the European equivalent of the walleye and one of the most prized freshwater predators in Europe. Its excellent low-light vision makes it a crepuscular hunter. Its delicate white flesh is considered among the finest of freshwater fish.
