Seychelles Spurdog

About the Seychelles Spurdog

The Squalus Lalannei, also known as the Seychelle’s Spurdog, is a deepwater shark that belongs to the Squalidae family.


Known only from the holotype (female: 78.8 cm TL)and paratype (male: 61.5 TL) collected during a research cruise by trammel net at 1,000 m off Alphonse Island, Republic of Seychelles in the Western Indian Ocean. The biology of the species is little known.


The depth distribution of the species is little known and it is possible that this shark has been caught by Seychellois fishermen without knowing it was a new species. Like many deeper water species, more information on biology, ecology and importance in fisheries are required to further assess status and any future conservation needs.
