Distribution sources
Identification
Large dark spots, a rounded snout and separate nasal flaps not reaching the mouth characterise Scyliorhinus stellaris. Also compare dorsal-fin position; size alone does not distinguish the two catsharks.
Habitat
North-eastern Atlantic and Mediterranean, particularly over hard, rocky and algae-covered continental-shelf bottoms.
Diet
Crustaceans, molluscs, cephalopods and bottom-dwelling fish.
Behaviour
It hides in rocky shelters during the day and becomes active at night. This biological rhythm alone does not justify recommending a night trip.
Indicative biological size
About 1 m in the DORIS description; this reference is neither a record nor a legal size limit.
Fishing context and precautions
Fishing in Wales names Scyliorhinus stellaris and lists fish, crab and squid baits over rocky ground; the Sea Angling Ireland account specifies mackerel strips. Indicative adaptation from a boat and spot where fishing is permitted: prepare a single-hook bottom rig, attach a strip of mackerel and lower it under control near the bottom without wedging the sinker among rocks. Choose line and weight that allow presentation control and withstand abrasion; if snagging recurs, retrieve and change the drift. On a bite, follow the tension and retrieve without prolonged exhaustion. General IFI elasmobranch precautions favour unhooking alongside the boat when possible, without a gaff; bring aboard only when necessary. Never suspend the shark by its tail or vertically, protect the gills and minimise handling. Abrasive skin and teeth require hands to stay away from the mouth. This Irish and Welsh adaptation grants no right to fish in France.
A distinctive feature
Its eggs are protected by a capsule with tendrils that attach to a support.
