In the animal family tree, everything traces back to the jelly.
H. atlanticus is commonly referred to as a "seven-armed" octopus. In the last 27 years, there have only been 3 sightings of this mysterious octopus.
Not only is it gross, but widely-accepted jellyfish cures apparently make the sting even worse.
NOAA scientists spotted an eerie creature in the depths of the rich waters of American Samoa.
Leatherback sea turtles, the largest reptiles in the world, are famous for their nomadic ways and open-ocean migratory nature. But researchers from Cornell have discovered a location along the Mozambique coast that houses what appears to be a permanent home for the leatherbacks.
El Niño phenomena is causing less rainfall in different areas including the Jellyfish lake in Palau. Because of the lack of rain, the lagoon becomes saltier driving both plankton and the jellyfish away.
Scientists recently picked up a distinct new sound using highly sensitive instruments: the hum of deep-water creatures at dusk and dawn as they move to and from the surface. Learning more about the mysterious sound could tell us more about response to climate and fishing.
A widespread parasite known to infect salmon and trout is actually a "micro jellyfish." This may change the way scientists define animals.
Jellyfish and lamprey (an eel-like creature) are sort of the expert, efficient swimmers of the seas. And hey, they have some competition. So it's meaningful that a recent study has findings on their wriggly secrets.
Researchers at Stanford, University of Michigan and Woods Hole recently developed digital tags for recording behavior of invertebrates. Before this, a full range of recordings of in-water creatures was only available for large mammals.
Any beachgoer, snorkeler, or diver can tell you that while the ghostly forms of jellyfish are beautiful to behold, you don't want to go anywhere near them. It's not uncommon for jellyfish stings to cause painful, paralyzing, or even lethal reactions, and it's often very difficult to tell which jellies are harmful. That's why researchers have looked into a new way to assess these bizarre creatures: by the length of their stingers.
A jellyfish-like colony of marine species uses a method similar to jet propulsion to move as a whole.
Jellyfish provide easy access to hunting grounds for some sea birds, since they attract small fish to hang around their tentacles in exchange for plankton.
For most, jellyfish have always been those overly alien things that float in aquariums and across our television screens. Some are even mistaken for drifting plants, barely moving as the currents dictate where they head. However, researchers have now identified one group of jellies that actively lure and capture prey - a revelation that soundly disproves assumptions that these creatures lead a mindless existence.
