Transcript of Atolla Jellyfish
Wyvellei jellyfish live in deep oceans throughout the world, from the Arctic to the Antarctic. They've also been found in the North Atlantic and Pacific, the Gulf of Mexico and waters around New Zealand. Their typical habitat ranges from 3,280 feet below the surface to more than 13,000 feet below the surface, where temperatures average between 29 degrees Fahrenheit and 2 degrees below zero Fahrenheit.
The Atolla jellys’ bodies, or bells, measure as little as 6/10 of an inch across to 8 inches across. A wyvillei usually has 22 marginal tentacles around the rim of the body and one hypertrophied tentacle, which might be 1.5 times to 36 times longer than the bell's diameter
Like many deep-sea Creatures, the Atolla jelly produce their own light, called bioluminescence. They use this ability differently than other animals, including the other five Atolla species, though. When a predator approaches, the Atolla jelly emit a flashing blue light that attracts other, larger predators to gobble up the threat. Of all colors, blue reaches the greatest distance underwater. This defensive strategy has earned them the nickname "alarm jellyfish."
Atolla wyvillei can reproduce asexually and sexually. Researchers have speculated that the jellyfish attach via their hypertrophied tentacles to enable the males to fertilize the females’ eggs. Like many other members of the Scyphozoa class, Atolla wyvillei can develop into polyps, asexually producing buds that grow into larvae.
The Atolla jellyfish has evolved with some sophisticated adaptations of its own to this rayless environment. It is outfitted with a series of long tentacles, around 2o in number, with one long, trailing tentacle that is thought to facilitate capture of its prey. But it is its defensive behavior that quite literally calls attention to this fascinating creature: when threatened, the Atolla jellyfish enacts a series of bioluminescent blue flashes, which circle around, much like the light atop a police car. Many creatures at this depth use bioluminescence as a defensive tactic, but scientists believe that the Atolla jellyfish uses it to draw the attention of other creatures who will eat the potential predator as it swims to safety.
