Starry smooth-hound
Fish · Last reviewed 2026-08-10
A small crab-eating shark of European coasts with crushing plate-like teeth rather than cutting ones, and white spots along the flank.
Safety
Injury while handling fish — Can cause injury needing treatment
The pavement teeth can crush a finger and the dermal denticles are abrasive enough to graze skin badly when the fish twists.
What reduces it: Keep fingers out of the mouth, support the fish with both hands rather than gripping, and wear gloves or use a wet cloth.
Starry smooth-hound is a small coastal shark that eats crabs. Its teeth are not the blades of a typical shark but flattened crushing plates arranged in a pavement, suited to grinding hard-shelled prey — which means it does not bite in the way people expect a shark to.
It is a slim, grey, elegant fish scattered with small white spots along the flank, and it hunts over sand and mixed ground in summer. It is a major target of European shore and boat anglers, prized for a fast, strong, clean fight on light tackle.
It gives birth to live young. That, combined with modest litter sizes and slow maturity, is why the species is treated carefully and released almost universally.
Identification
FishingHQ holds no photograph of this species whose identity and licensing it can vouch for, so it is not showing one. Misidentified fish photographs teach identification wrongly, and a picture with an unchecked caption would be worse than none. The identification points below are what to look at instead.
- Scientific name
- Mustelus asterias
- Family
- Triakidae
- Water
- Saltwater
- Conservation status
- Near Threatened
- Regions
- Britain & Ireland, Western Europe, Mediterranean
- Small white spots scattered along a plain grey flank, giving the species its name.
- Flattened pavement-like crushing teeth rather than cutting blades.
- Two dorsal fins of similar size with no spines, and a slender body with a pointed snout.
- No black-tipped fins and no bold bars, which separates it from other small European sharks.
Size
- Typical
- 2–5 kg (4.4–11 lb)
- Large
- 6–10 kg (13–22 lb)
Exceptional: FishBase records a maximum of 154 cm and 4.8 kg
Lifecycle and reproduction
Slow-maturing and long-lived by comparison with bony fish, bearing live young in modest numbers after a long gestation. Reproductive output is low, which is the basis for the release culture around the species.
Viviparous, with females giving birth to live young after a gestation of about a year. Litters are small, and pupping occurs in shallow coastal areas in summer.
Feeding and senses
Feeds principally on crabs and other crustaceans, crushing them with plate-like teeth, along with small fish and molluscs. Hunts over sand and mixed ground close to the bottom.
Locates prey by smell and by electroreception close to the bottom, which is why crab baits fished hard on the ground are so effective and why scent trails matter.
Through the year
Moves inshore in late spring and summer to feed and to pup, and moves offshore into deeper water in winter. The summer inshore period is the whole of the recreational fishery.
Distribution
Northeast Atlantic: British Isles and North Sea to Canary Islands, including the Mediterranean and Mauritania
This is a biological range — where the species occurs, not a prediction that you will catch one. To browse the fishing geography FishingHQ holds, start at fishing places.
Why anglers care
A prime European summer shore and boat target, taken on peeler crab and hermit crab fished on the bottom over sand and mixed ground. Its significance is the quality of the fight on light tackle and its accessibility from open beaches, and it has become one of the most sought-after British shore species. Almost universally released.
Handling and returning
It does not have cutting teeth, but the crushing plates can still injure and the skin is abrasive enough to remove skin from a forearm. Support the body horizontally, never lift a shark by the tail alone, keep it off dry sand, and return it promptly and head-first into the water.
Skin like sandpaper, crushing plates, and a shark that is not a dogfish
Smooth-hounds are frequently confused with the spurdog and the lesser-spotted dogfish, and the handling differences between them are exactly the things that matter.
WHAT IT DOES NOT HAVE. No dorsal spines. That distinguishes it from the spurdog, which carries a venomous spine in front of each dorsal fin and is a genuinely hazardous fish to handle. A smooth-hound is safe to hold across the back in a way a spurdog is not, and knowing which one is in your hands is the first requirement.
WHAT IT DOES HAVE. Dermal denticles — skin that is functionally sandpaper. A smooth-hound drawn across a forearm removes skin, and holding a thrashing one bare-handed leaves the marks for days. The abrasion runs one way, so the damage happens when the fish moves against the grain.
AND CRUSHING PLATES rather than teeth. Smooth-hounds eat crabs and shellfish, and the mouth contains flattened pavement-like plates. It cannot cut a finger; it can crush one uncomfortably.
HANDLING. Wet cloth or gloves, support the body along its length, and keep the fish flat. Sharks lack the skeletal support of bony fish and a smooth-hound held vertically or by the tail is being damaged internally.
AND THEY ARE OFTEN CAUGHT IN NUMBERS ON A RISING TIDE from open beach ground, which is where the actual hazard lies: an angler working fish quickly at the water's edge on a flooding tide, watching the rod rather than the sea.

Smoothhound and crab: one diet, and a season built on it
Smoothhound fishing is organised around a single prey item to a degree matched by almost nothing else in British sea angling, and knowing why explains the bait, the season and the ground together.
THE DIET IS CRUSTACEAN. Smoothhounds have pavement-like crushing plates instead of cutting teeth, and they eat crabs, hermit crabs and other crustaceans almost to the exclusion of anything else. That is not a preference; it is what the mouth is for.
SO PEELER CRAB IS THE BAIT, AND THE REASON IS BIOLOGICAL. A peeler is a crab about to moult, which has shed the hard shell beneath and is soft and defenceless underneath the old one. It is the most vulnerable a crab ever is and predators target it specifically. Hardback crab works and peeler works better, and the difference is not superstition.
WHICH TIES THE SEASON TO THE CRABS RATHER THAN TO THE FISH. Smoothhound appear inshore as water warms and their arrival coincides with the crab moult, which is itself temperature-driven. The fishery has a season because the food does. In a cold spring both are late, together.
THE GROUND FOLLOWS THE CRABS TOO — mixed and rough ground, mussel beds, and the margins of estuaries and banks where crabs are abundant. Clean open sand holds fewer.
AND THE FIGHT IS THE OTHER HALF OF THE REPUTATION. Smoothhound run hard and long for their size and are among the best sporting fish available from British shores, which combined with their being poor eating makes the fishery almost entirely catch-and-release.
IDENTIFICATION MATTERS BEFORE HANDLING. Two smoothhound species occur, and both are routinely confused with the spurdog, which carries a venomous spine in front of each dorsal fin. The handling section on this record covers what follows from that; the short version is to know which fish is in your hands before you grip it.
AND THE CRAB SUPPLY IS A CONSERVATION QUESTION. Peeler crab is collected from the shore, collection can damage the habitat it comes from, and it is regulated in places. Return turned rocks the way they were found, and check local rules on collection.
