Cuisine & Edibility

Atlantic Herring

Soft, oily flesh with a rich, pronounced flavor and high omega-3 content. Culturally essential across Northern Europe — pickled, smoked, salted, or prepared as Bismarck herring or rollmops.

Great Hammerhead Shark

Critically Endangered — consumption strongly discouraged. Fins are historically traded but the species faces severe population decline; eating this fish is ecologically irresponsible.

Species Overview

Atlantic Herring

The Atlantic herring is one of the most abundant fish species on Earth, forming massive schools of billions of individuals. It has played a crucial role in European history, fueling trade routes and even wars.

Great Hammerhead Shark

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.
