  • The Small-spotted catshark is the most common shark in Europe and can measure up to around 1 meter.
  • During the day it hides in crevices and caves and only comes out at night to hunt.
  • They group together in separate schools, made up of only females and only males. They both live in coastal waters and only come together at the end of summer, for mating, in deeper waters.
  • The female keeps the sperm and deposits the eggs throughout the year (only two at a time).
  • The eggs, capsules or mermaid purses, have very resistant threads at the ends that serve as anchors that are attached to algae or other structures.
  • Females exhibit philopatric behavior (from the Greek “home love”), that is, they return to the place where they were born, fed or laid their eggs.
  • They detect weak electrical fields emitted by other animals (ampullae of Lorenzini).
  • Its skin is so rough that it was used as sandpaper!
