Dogfish sharks, Squalus sp., are a popular teaching specimen for biology and anatomy courses, specifically used for the teaching of cartilaginous fish anatomy. They are also great animal models to study comparative and vertebrate anatomy.

Dogfish will either be species Squalus sp. or Mustelus canis.

The harvesting of dogfish sharks is regulated by National Marine Fisheries to protect the species. Quantities used by our industry are very small in relation to the overall harvest.
