Giant Jellyfish Found By Divers In The UK SUBSCRIBE: http://bit.ly/Oc61Hj A jellyfish filmed swimming off the coast of Cornwall is thought to be the biggest ever caught on camera in Britain. The four-foot wide barrel jellyfish, which is also known as the dustbin-lid jellyfish, was filmed by diver and archeologist Robert Lenfert. Robert, 42, and his wife Natasha, 39, met the giant creature off Pendennis Point, near Falmouth, Cornwall. The pair swam beside the giant sea beast for half an hour as it glided through the water.

WTF? A SWARM OF GIANT JELLYFISH!! Cornwall Humbled by Cornwall jellyfish encounter! Huge jellyfish – described as being the size of dustbin lids – are being washed up on beaches in Cornwall. Although there are a number of species of jellyfish in Cornish waters, it is thought these are barrel jellyfish – the largest jellyfish found in UK seas. Indeed one marine enthusiast, who studies Cornwall’s coastline, said that he has seen more barrel jellyfish over three days last week than in the previous 15 years put together. Rupert Kirkwood, who is known as The Lone Kayaker, wrote on his blog last Thursday: “There are more barrel jellyfish around the coast of SW England than I have ever seen in 15-plus years of sea kayaking. A lot more. I have seen more in the last three days than all the other years added together … 91 on Tuesday, 120+ on Wednesday and 40+ today. “This number of any other jellyfish is not unusual, but barrel jellyfish are so BIG that this is really quite a phenomenon. Their ‘bell’ can be two foot across and they can weigh in at over 30kgs.” Rupert added: “Their appearance seems to have coincided with a plankton bloom (upon which they feast) that has probably been caused by the sunny weather.” He believed there could be “millions” in our waters. “As I paddle along I can see jellyfish beneath the surface up to about 10ft from my kayak, so I only see a tiny fraction of the vast numbers out there. The three locations I have seen them over the last three days are 50 miles apart so there must be millions of these large and mysterious creatures floating about around our coast. “Actually it’s a bit unfair to imply that they drift about passively. On the contrary they seem to be very motivated to get somewhere with the relentless pulsating of their ‘bell’, although they maybe don’t know exactly where that somewhere is as they haven’t got a brain.” The influx of barrel jellyfish means a large number are being washed up on our beaches. Indeed I posted images of three jellyfish on Porthcurnick and Pendower beaches on the Roseland peninsula last Friday.

During these first ever ROV dives in Revillagigedo Archipelago, the Nautilus team has encountered some truly otherworldly organisms. This Deepstaria jelly awed us with its shapeshifting abilities as its bag-like bell inflated and undulated with current created by movement of ROV Hercules. Capturing prey in its voluminous bell, a strikingly geometric network of canals delivers nutrients throughout this large jelly’s body. This close encounter was captured with both our normal ROV Hercules HD camera and a low light camera for bioluminescence designed by Dr. Brennan Phillips at University of Rhode Island's Graduate School of Oceanography and David Gruber at the City College of New York/Baruch College. ------------------------------------------------ E/V Nautilus is exploring unknown regions of the ocean seeking out new discoveries in biology, geology, and archaeology.

Thinking about hitting the beach this weekend? Watch out for the giant jellyfish. WBZ-TV's Juli McDonald reports.

Giant jellyfish-like creatures have forced the closure of a South Coast beach to swimmers. Horseneck Beach in Westport will be inspected Tuesday morning for Portuguese man o' war, which were seen Monday afternoon. The animals are closely related to jellyfish with tentacles that can grow to 100 feet and give painful stings. The beach and parking areas remain open to the public. The water is expected to reopen to the public Tuesday morning after it's inspected and deemed clear of man o’ war.

WBZ-TV's David Wade reports.

Subscribe to ITN News: http://bit.ly/1bmWO8h Described as a gentle giant of the jellyfish world, a huge barrel jellyfish made an appearance in an estuary near St Mawes in Cornwall. Marine awareness officer Matt Slater and his dog Mango decided to swim out for a closer look and captured this incredible footage. The alien looking creature weighs a whopping 20 kilos and is said to measure up to one metre in diameter. More barrel jellyfish are said to have started turning up around Cornwall and this is down to an increase in their food source. Despite their size, barrel jellyfish are harmless to humans, and are more aware of the water world than we think. They're constantly swimming up and down in the water looking for plankton. Matt has also reported sightings of compass and moon jellyfish in Cornish waters. Cornwall's north coast has also seen huge numbers of blue jellyfish, which unlike barrel jellyfish, can give a mild sting. Report by Claire Lomas.

Stygiomedusa gigantea is one of the largest invertebrate predators known in the ocean, yet little is understood about its ecology and behavior. Stygiomedusa lacks tentacles, but has four extraordinarily large oral arms that are presumably used to envelope prey. The swimming bell of this spectacular medusa can reach over one meter across with arms over ten meters long. A symbiotic relationship between Stygiomedusa and the fish, Thalassobathia pelagica, was confirmed in 2003 when scientists from the Monterey Bay Aquarium Research Institute (MBARI) filmed the pair swimming together in the Gulf of California. The fish has adapted to using the medusa as a hiding place in its open ocean habitat. In twenty-seven years of scientific ROV surveys, researchers at MBARI have been lucky enough to observe this rare animal seven times, from depths of 750 meters down to 2187 meters.
