Cuisine & Edibility

Grand requin marteau

Rascasse volante

Sweet, buttery white flesh once spines are safely removed; increasingly promoted as a sustainable food source in Atlantic waters where it is an invasive species.

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.

Rascasse volante

The red lionfish is a venomous coral reef fish native to the Indo-Pacific. Its ornate, striped body and fan-like pectoral fins make it popular in aquariums, but it has become a destructive invasive species in the western Atlantic and Caribbean.
