Biology
The nursehound spends most of the day hiding in the rocks, but leaves during the night to patrol the bottoms it inhabits. It feeds on fish, shellfish and even small sharks. The eggs are laid in shallow water and, protected by a strong capsule, are attached to algae. They hatch after nine months with fully-formed juveniles.
Conservation
Given its irregular distribution and evidence of decline in some areas of the Mediterranean Sea, the nursehound is listed as "Nearly threatened".
Curiosities
It may be confused with the smallspotted catshark, but reaches larger dimensions.
