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.

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.

Giant Jellyfish Spotted and found by scuba Divers . Giant jellyfish spotted by divers. Jellyfish as big as a human spotted off Cornwall coast. Human-sized mammoth jellyfish found near the coast of marine oceans. A pair of divers swimming off the southwestern tip of England hit the jelly jackpot last week after crossing paths with a hulking barrel jellyfish (Rhizostoma Pulmo) — a rarely seen species that can grow about as large as a full-grown human. Luckily, they filmed the whole thing. The divers — biologist Lizzie Daly and underwater cinematographer Dan Abbott — shared the encounter in a Facebook video posted Saturday (July 13) as part of the Wild Ocean Week campaign — a series of videos showcasing the oddities of the deep to help raise money for the United Kingdom's Marine Conservation Society. Daly and Abbott were diving off the coast of Cornwall, the U.K. when they saw the giant jelly emerge from the murky water. Also called the dustbin-lid jellyfish, the species is characterized by eight puffy arms capped by stinging tentacles and a large, globular head that lends the creature its unglamorous nickname. Barrel jellyfish sometimes wash up on the shore, Daly told Vice, but it's rare for a diver to swim face-to-faceless-head with one of the massive blobs. While the barrel jellyfish is the largest species of jelly found in U.K. waters, it's a mere shrimp when compared to the lion's mane jellyfish (Cyanea capillata), the largest known species in the world. This coldwater jelly is known for its galaxy of 1,200 long, trailing tentacles, which can bring an individual creature's total body length to up to 120 feet (36.5 meters) — which is longer than the average blue whale. This tangle of tentacles is so massive that a single lion's mane jelly may be able to sting 50 to 100 people in just a few minutes if currents carry the jelly too close to a populated coast — a fun fact that a group of unlucky New Hampshire beachgoers learned the hard way in 2010.

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.

Deep Sea Gigantism | Why Creatures of the Deep Grow so Large. Enter at https://www.omaze.com/naturalworldfacts for your chance to win a Custom Tesla® Model S-APEX and support a great cause, the Petersen Automotive Museum. The experience closes on January 27th at 11:59pm PST and I promise, you don’t want to miss this! Deep sea (abyssal) gigantism demonstrates the role of natural selection in driving evolution and survival, particularly in an environment characterised by challenging conditions and limited resources. Evolution tends towards the most effective adaptations to grant animals the best chances of survival. And whether large or small, evolution selects for the best-adapted body size to survive these conditions. Though widely debated and often controversial, the research that has been done into the science behind deep sea gigantism has significant implications in the human world; it is believed that climate change may have a greater impact on ocean dwellers than any other population of animals. As the colder oceans warm up, the balance of temperature, oxygen supply, and what organisms are present, will throw the equilibrium off course. And the giants, which rely so heavily on this fine balance, may be the first to go.
