Tope

Galeorhinus galeus

Critically Endangered

It faces an extremely high risk of imminent extinction in the wild. See full glossary

The tope is a slender shark of temperate waters, well known in Spain because it is the basis of the Andalusian dish cazón en adobo. Its populations have collapsed worldwide: it was fished intensively for its meat and for its liver oil, rich in vitamin A, and today it ranks among the most threatened coastal sharks on the planet.

Fun facts

  • It is the fish in cazón en adobo, one of the most popular dishes of Andalusian cooking, and that steady culinary demand sits oddly with its position: the species is today listed as critically endangered worldwide.
  • During the Second World War it was fished on a huge scale for its liver oil, extremely rich in vitamin A, and that exploitation crashed the Pacific populations before synthetic vitamin existed.
  • It makes enormous migrations: individuals tagged in the European Atlantic have been recovered thousands of kilometres away, and there are populations that cross hemispheres.
