List of Types of Sharks in British Waters
I grew up living next to British coastal waters, in south west Scotland, specifically next to the Atlantic Ocean to the north of Ireland. Despite swimming in the sea from April through to September, I saw no sharks, apart from the occasional dogfish, caught accidentally when out in a boat fishing for herring or mackerel.
Dogfish are part of the shark family, and it was specifically Squalus acanthias, the spiny dogfish, that we used to catch accidentally.
They have two spine on their backs, one behind each of its two dorsal fins, and when captured, it is not unknown for them to arch their back and pierce the skin of whoever is closest to it. These spines are poisonous, so catching a dogfish meant having a hammer ready as you pull it on board, to knock it out so that the hook could be released.
I've seen porpoises off the west coast of Scotland, but never sharks.
Yet they are there, which I'm awfully glad I never knew about when I was growing up, else I would never have had so much fun catching crabs among the rocks or snorkeling for the tiny sand flounders that live in the shallow waters.
Alopias superciliosus - bigeye thresher shark
The first confirmed sighting of the Bigeye thresher shark was a juvenile, off the coast of Cornwall in 2001. Thresher sharks are fish eaters, and have an elongated tail which they whip to stun their prey. They are not considered to be dangerous to man.
Alopias vulpinus - thresher sharks
Thresher sharks can grow to 20' long and are more commonly seen in the warmer waters of the English channel. In 2007, one was caught in the North Sea off the Yorkshire coast. Threshers are easily identifiable because of their elongated caudal fins.
Carcharhinus longimanus - oceanic whitetip
An extremely dangerous shark, the oceanic whitetip is normally seen in the deep oceans of the world where during the last world war they were responsible for the deaths of thousands of servicemen shot down at sea. There has only been one report of a fisherman catching an oceanic whitetip in British waters, and it has not been confirmed.

Amazing BBC footage of a basking shark
Carcharodon carcharias - great white sharks
Again this dangerous man-eating shark has apparently over the years had many sightings in British coastal waters, but none have been confirmed.
Centrophorus granulosus - Gulper shark
Gulper sharks are a kind of dogfish that lives in deep water, reaches 1.5M (4 feet) in length, and is harmless to man.
Many of the sharks in British coastal waters are harmless to man, even the biggest of them all, the plankton-eating basking shark.
Many are only found in the deeper waters miles out from the coast. About a third of the sharks listed above are only found in deep water including the Portuguese Dogfish, Black Dogfish, Kitefin Shark and Gulper Sharks.
Some are only summer visitors.
Indigenous sharks in British waters are suffering the same fate as sharks world-wide. Their numbers are dwindling rapidly. Warm water sharks are appearing in greater numbers, for reasons unknown.
Slow breeders and late developers, sharks simply can't reproduce quickly enough to replace their huge numbers lost through over-fishing.
Sharks are prized for their fins, destined for the Asian market where they are turned into shark's fin soup for the increasingly wealthy Chinese people who serve this dish as a mark of deep respect to other wealthy Chinese people. It's a status symbol, if you like.
From all accounts, shark's fin's soup would be awful if it weren't for the chicken stock and vegetables added in to make a nice broth. The Shark's fin itself is tasteless and ends up looked like pasta, which to be honest is pretty tasteless too.
Many industries used to use the fish oil extracted from sharks but have agreed to discontinue and find other sources of what they need, because the plight of sharks is so serious.
Sharks in British Seas Trailer
Centroscyllium fabricii - black dogfish
The black dogfish is a deep water shark that barely grows longer than 2 feet. It is frequently an accidental by-catch of deep sea trawlermen who discard it overboard as it is worthless to the fish market. It's numbers have seriously declined and it is now in the near threatened list.
Centroscymnus coelolepis - Portuguese dogfish
This is the deepest-living shark known, having been found at depths of 12,000ft under the sea. It catches its prey by looking for the bio-luminescence that radiates from other deep sea creatures. No sunlight permeates to this depth. They typically reach about 3 feet long and are prized by fishermen for their liver oils which are widely used in industry. It is classed as 'near threatened'.
Cetorhinus maximus - Basking shark
The second biggest of all sharks, the basking shark can reach 40 ft in length. Only the whale shark is bigger. Found in temperate waters the world over, basking sharks are harmless plankton eaters in spite of their great size. There have been numerous sightings of the basking shark around British coastal waters where it is a protected species. You will get jailed for six months if you harm a basking shark, so be warned.
Chlamydoselachus anguineus - frilled shark
Like a mythical demon snake, the frilled shark has an elongated, eel-shaped body. They can reach about 6.5 feet in length and inhabit the ocean floors at the edge of continental shelves between 160 - 660 feet deep. They can eat creatures twice their size, including other sharks, but there are no reports of attacks on humans. They are on the 'near threatened' list.
Dalatias licha - Kitefin shark
Growing to about 4.5 feet long, the kitefin shark, otherwise known as the seal shark, black shark or Darkie Charlie, lives in the ocean floor in deep waters down to 2000 feet, but it has been captured at 6,000 feet down. A member of the dogfish family, it's a solitary predator and eats just about anything, including other sharks. It has never eaten man because we don't go that deep in the ocean, though one man did once wearing full deep-sea diving gear which would have protected him. Kitefin sharks are 'near threatened' because of sea sea fisheries who target them for their meat, skin and liver oil.
Dipturus batis - common skate, blue skate
The common skate is a member of the shark family. Growing to 10 feet in width, these deep sea creatures that have been found in depths of 2,000 feet are now extremely rare if not extinct.
In the IUCN Red List, it is listed as critically endangered.
For many years, anglers, who occasionally catch skate while fishing, have operated a voluntary code of returning them to the sea unharmed.
Commercial fishermen have been encouraged to do the same.
In 2006, twenty four of their egg cases were washed ashore in Caithness in northern Scotland, perhaps showing that they are still around even though seldom seen.
Echinorhinus brucus - bramble sharks
Bramble sharks (or spiny sharks) are deep-water creatures, living on the sea bed down to a depth of 3000 feet. Their bodies are covered with denticles (which are like teeth) which is why they are called after the thorny bush. The denticles are luminescent in deep water. They grow to 13 feet in length.
Quite harmless to humans, probably because of the depths it lives at, the bramble shark is listed as 'data deficient' by the IUCN, as no-one knows if their numbers are declining or not. They live too deep to be fished even by deep sea fishermen.
Etmopterus spinax - velvet belly lantern shark
This is another deep-water dogfish, that lives at depths of down to 8,000 feet. Unfortunately they don't always stay at this depth and are frequently caught by deep sea fishermen as a by-catch.
It gets its name velvet belly from its distinctive two-tone coloring which is black underneath and brown on top, and the lantern is obvious from the photo. It is luminescent.
It's a small shark that only grows to 18" long.
Galeorhinus galeus - tope shark
Also known as the school shark, the tope shark is a big lad that grows to 7 feet long and has been found at depths of 1,800 ft, but which lives and travels in shoals at much shallower depths. Harmless to man, it is being fished out of existence. It's fins, meat and liver oil are all hunted for their commercial value, and it is on the IUCN red list as 'vulnerable'.

Galeus melastomus - blackmouth catshark, blackmouth dogfish
The catshark is among the most common types found in our oceans and is not on any endangered list.
It grows to about 2.5 ft, with, like most shark species, the females being bigger than the males. They live in waters from 500 ft down to 4,500 ft and are frequently caught by fishermen as a by-catch, and discarded because they are worthless.
Ginglymostoma cirratum - nurse shark
Why a nurse shark should be found in British waters is a mystery because this is a tropical or subtropical water fish. It cannot be blamed on global warming, because the sea temperatures off England ranges from 6 to 20+oC (43 – 60+oF) and has done for the last 3000 years.
The nurse shark is a shallow water shark that hides under rocks that are only a metre or 2 deep during the day, coming out to feed at night. They can give a nasty bite so it is best to stay away from them. In 2001, two divers identified an immobile shark at the bottom of the English Channel near Alderney as a nurse shark.
Heptranchias perlo - sharpnose sevengill shark
This is not a pleasant shark to encounter. It's ferocious, a top predator despite its relatively diminutive size ( it reaches just under 4 ft in length). It lives at a depth of 1000 - 3000 ft, and is occasionally caught as a by-product by deep sea fisheries and long line trawlers. In captivity they are exceptionally dangerous and will try to bite their captors. It's not supposed to be present in British coastal waters at all, preferring warmer seas, but has been seen twice, once off Cornwall and another time of southern Ireland.
Hexanchus griseus - blunt-nosed six gill shark
Also known as the cow shark, it grows to 18 feet. Its a deep water fish, typically ranging in waters between 300ft - 6,000 ft deep. They tend to rise to the shallower waters to feed at night. They are slow moving creatures, but can attain amazing speeds when chasing prey. They have never attacked man. It is on the 'near threatened' list of the IUCN.
BBC video about scientific evidence disproving shark attacks in British waters
Isurus oxyrinchus - shortfin mako
A summer visitor to British shores, the shortfin mako grows to 7 - 9 feet on average. An ocean-going pelagic fish, it can travel great distances at great speeds, depending on whether it is after a mate or prey. They have been known to cross the Atlantic, in fact do so several times a year. They can travel at 30mph, perhaps faster, so don't bother trying to outswim it if it is chasing you! The shortfin mako, which is dangerous to man, is on the IUCN critically endangered list.
Lamna nasus - porbeagle shark
Reaching over 8 feet in length, the porbeagle shark is on the critically endangered list. It would appear that the English Channel around the Channel Islands is a nursery ground for them, because in 2009 an angler caught a newly born one there. Extremely shy of man, porbeagles, who have never attacked humans, will quickly turn tail if they suspect a human is around. When caught, however, they will fight to the bitter end.
Mustelus asterias - starry smoothhounds
Starry smooth-hounds are shallow water sharks that live in waters down to 300 feet, but commonly come right into the shallows in summer months.
They can reach 4 feet in length, and are harmless to man.
They are not commercially fished and so their numbers are not considered to be at risk.
Mustelus mustelus - common smoothhound
This shark is very similar to the starry smooth-hound, except that it doesn't have spots on its back. It also prefers slightly deeper waters. It is commonly mistaken for the tope shark except it's second dorsal fin is larger. Common smooth-hounds frequently group together in packs, just like dogs, hence the name.
Prionace glauca - blue shark
The blue shark is the most wide ranging geographically of all fish. Being pelagic, it is to be found in every sea and ocean the world over. They can reach 12.5 ft in length, and frequently travel in schools that consist of similarly-sized sharks, that are either all female or all male. They are not considered dangerous although they have caused 4 fatalities, usually after being caught. Up to 20 million of them are fished from global waters annually, and their numbers are now classed as 'vulnerable' on the IUCN list of threatened species.
Blue shark off coast of Wales,summer 2012
The Daily Mail carried the story of this blue shark, and described it as being a pup. This would have been very unusual, because although blues are to found in British waters, it is widely believed their nursery grounds are on the other side of the Atlantic Ocean.
Looking at the video, I would estimate this fish to be 5 - 6ft in length, and at that stage may be considered adult, and is indeed the average size for an adult blue shark, although many can grow longer. Read more about blue shark facts.
Scyliorhinus canicula - small-spotted catshark
Also known as the lesser-spotted dogfish, this shallow water catshark is, if anything, increasing in numbers. They can reach 3 ft in length, and their main diet is small fish and crustaceans.
Commercial fisheries largely discard them, and scientists have learned that a massive 98% of the discarded catch survives.

Scyliorhinus stellaris - nursehound, large spotted dogfish
Similar in appearance to the small-spotted catshark, the nursehound is identifiable by having larger spots on its upper side. It can grow up to 5ft long, and lives in depths of down to 200 feet, hiding under rocks by day, and coming out to feed at night. Not considered dangerous to man, unless caught, when it can attack. It can twist its long body round to bite the hand that holds it. Nursehounds are being fished out of existence are on the 'Near Threatened' list of the IUCN. Unfortunately for them, when beheaded and chopped up, they look and taste like salmon. If you order 'rock salmon' in a restaurant, this is what is served. It's other menu names are 'flake' or 'rock eel'.
Somniosus microcephalus - Greenland sharks, grey sharks
Also known as sleeper shark, gurry shark, ground shark and grey shark, Greenland sharks are the northermost shark species. They grow to a massive 24 ft long and are apex predators and scavengers. They live in waters down to at least 7,000 ft and their meat is poisonous. Icelanders and Greenlanders consider it a delicacy. The meat has to be dried and fermented to get rid of the poison. Although they are on the IUCN's 'near threatened' list, there is some evidence that their numbers are increasing around the UK.
Sphyrna zygaena - smooth hammerhead
The smooth hammerhead can reach up to 16 feet long, and is the only hammerhead species that likes cool waters. They frequently travel in huge schools that can number in their thousands, but this is becoming rarer as overfishing and shark-finning has reduced their numbers by so much, that they are now listed as 'vulnerable' on the IUCN list. Potential man-eaters, it is fortunate that they do not encounter many human swimmers so far out to sea in the cooler waters. In the open ocean, they tend to stay close the surface but have been spotted under-water as deep as 600 feet.
Squalus acanthias - spiny dogfish
The spiny dogfish was once the most abundant shark in the world, but due to overfishing, its number are declining rapidly and it is now on the 'vulnerable' list of the IUCN. It is recognisable by its two spines to the rear of its pair of dorsal fins which are poisonous. They grow to about 5 feet in length, and are found in shallow waters around the British Isles, but in deeper waters in other warmer seas and oceans.
Squatina squatina - angel shark
Attaining a maximum length of almost 8 ft, the angel shark lives in the sea-bed on continental shelves down to 500 feet deep. Its body is flat and wide and resembles a ray. Eaten as 'monkfish' it is now almost extinct and is considered to be 'critically endangered' on the IUCN list. They lie half-buried in the sand and ambush their prey. They can give a nasty bite to humans if disturbed, although are generally not aggressive.
