Portal:Sharks
Sharks (superorder Selachimorpha) are a group of fish species with a full cartilaginous skeleton. There are over 400 extant species of shark, as well as numerous extinct species known from recovered teeth and bones. Due partially to fear of shark attack, sharks often feature heavily in popular culture. Template:/box-footer

Nursehounds have nocturnal habits and generally hide inside small holes during the day, often associating with other members of its species. A benthic predator, it feeds on a range of bony fishes, smaller sharks, crustaceans, and cephalopods. Like other catsharks, the nursehound is oviparous in reproduction. Females deposit large, thick-walled egg cases, two at a time, from March to October, securing them to bunches of seaweed. The eggs take 7–12 months to hatch. Nursehounds are marketed as food in several European countries under various names, including "flake", "catfish", "rock eel", and "rock salmon". It was once also valued for its rough skin (called "rubskin"), which was used as an abrasive. The conservation status of this species has not yet been evaluated by the International Union for Conservation of Nature (IUCN).
