Tope

Galeorhinus galeus

Critically Endangered

At extremely high risk of imminent extinction in the wild.

Spotted something wrong?

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 A 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.

How to help

The tope is classified as critically endangered. Organisations such as the IUCN, WWF and the Wildlife Conservation Society work specifically on its conservation and that of its habitat; looking into their programmes is a good starting point if you want to get involved.

It's documented in 12 protected areas — one reason why protecting these places matters for its conservation.
