Sharks, dolphins and now blooms of jellyfish spotted off Westcounty shores

HUGE BLOOMS of jellyfish have been spotted across west Cornwall as the summer season has swept in.

Residents and visitors have reported significant numbers of the marine animals, with many seen around the Isles of Scilly, Land’s End and Sennen since the warmer temperatures arrived.

“They seemed to be coming all the time.”

Mrs Whitney described most of the jellyfish as blue in colour, and noted that despite reports that their stings could be vicious, some people were swimming in wetsuits close by.

The Marine Conservation Department noted sightings have been logged of both moon and blue jellyfish around west Penwith.

According to the organisation most present in Cornish waters are relatively harmless, however more dangerous species have been known to stray to the peninsula.

“We are getting reports off the Sennen coast,” said Abby Crosby, a marine conservation officer.

“We have heard of large sightings - there have been some seen on beaches and out at sea.”

She also said that while rare, some more dangerous types have been identified.

“There have been two sightings of Lion’s Mane jellyfish (the largest known in the world) - but it’s unlikely you will encounter these off our coasts.”

The marine life specialist added the jellyfish can be present throughout the year, but often appear in force over the summer months.

“There could be millions - or there could be hundreds,” she said.

Some west Cornwall residents have taken to Twitter to discuss the jellyfish activity after spending time at nearby beaches.

Frank Batt said that there were “a lot at Sennen at the weekend,” while Lee Palmer said he saw blue, compass and common jellyfish while visiting Porthcurno.

Leatherback turtles, which feed on jellyfish, have also been seen, while last week a diver was visited by blue sharks just 10 miles from Penzance’s shoreline.
