10 species of shark could be heading towards UK waters due to warmer seas

At least 10 types of shark could be heading towards the UK due to searing heatwave temperatures warming the sea.

Experts claim that species of sharks currently found in warmer parts of the world, such as hammerheads and blacktip sharks, may be swimming in British seas within 30 years as the climate changes.

A new “shark map” reveals the places where the fish are already found in UK waters.

The startling research names Cornwall as the country’s shark capital with at least 20 species found off the coast, followed by the Scilly Isles and Devon.

An estimated 10 million small and 100,000 larger sharks from 40 different species are found in the seas around the UK.

Due to climate change, more species could be heading towards the UK from places such as the Mediterranean and the coast of Africa as seas become warmer, according to the research commissioned to mark Nat Geo WILD’s week-long “Sharkfest” of TV programming this week.

The 10 new species of shark that could inhabit British waters by 2050 are:

Great hammerhead

Blacktip shark

Sand tiger or spotted raggedtooth shark

Bigeye thresher

Longfin mako

Bronze whaler or copper shark

Oceanic whitetip shark

Silky shark

Dusky shark

Goblin shark

Meanwhile, species already found in UK waters, such as thresher, basking and nursehound sharks, are in decline due to over-fishing and other problems.

They require protection, according to Dr Ken Collins, from the University of Southampton, based at the National Oceanography Centre, and former administrator of the UK shark tagging programme.

Dr Collins, who produced the research, said: “It’s likely we will be seeing more sharks spread from warmer regions such as the Mediterranean Sea towards our waters in the UK over the next 30 years.

“These include the likes of blacktips, sand tigers and hammerheads, which are currently found swimming off the coasts of Spain and Portugal.”

He added: “Though while the potential number of shark species around the UK may increase in the next few decades, the overall number of sharks, especially the larger ones, will fall as a result of over-fishing, plastic waste and climate change.

“It’s really important we work together to prevent a premature extinction of these wonderful creatures.”

He also said he saw “no reason” why there should not be great white sharks in UK waters, as they were found in colder waters off South Africa and favoured seals – found in Cornwall – to eat.

However, numbers of great whites, hit by something of an image problem since the movie Jaws, are in decline worldwide so the chances of seeing them in the UK falls each year, he added.
