Terrifying moment rare 6ft shark spotted circling in Cornwall harbour

THIS is the terrifying moment a 6ft shark was spotted prowling off a Cornwall harbour.
The great blue shark was seen inside Newlyn Harbour near Penzance on Wednesday.
Footage showed its fin poking out of the murky water as it searched the harbour for something to eat.
Local William Harvey told : "I spotted the 6ft blue shark swimming underneath the harbour wall.
"Of all the wildlife I've seen in the harbour - including dolphins, seals and even a deer swimming one early morning - it was definitely the biggest surprise."
Blue sharks can be found swimming in the English Channel from June until October - but usually stay at least ten miles away from the shore.
The Wildlife Trust said: "Blue sharks are active predators and feed mainly on small fish and squid - though they have been known to take seabirds and other small sharks too.
"They even feed on fish that live near the seabed and have been recorded at depths of up to 350m."
It is very rare to see a blue shark come as close to land as the one in Penzance.
Blue sharks are metal blue on top and white underneath - with distinctive long front fins.
The largest one ever caught in UK seas weighed a whopping 256lbs and was 9ft long.
It comes after dozens of sharks washed up on a UK beach - and no one knows why.
A baby dolphin also died surrounded by horrified tourists at a famous UK beach.
