Jellyfish serve important roles in marine ecosystems by providing food for predators, controlling populations of other organisms, and cycling nutrients in the water. They are also used in medical research to study neurobiology and bioluminescence. Additionally, some species of jellyfish are used in the food industry for human consumption.
An Israeli start-up company called Cine'al has developed a super-absorbent substance made from jellyfish known as hydromash which they claim can be used to make diapers, tampons, and paper towels. Hydromash was inspired by research from the University of Tel Aviv, which found that jellyfish were made up of a material that could "absorb high volume of liquids and hold them without disintegrating or dissolving."
It only harms organisms by stinging it's predator(s). It doesn't help any organism at all.
Common jellyfish species found near Ft. Lauderdale, Florida, include the moon jellyfish (Aurelia aurita) and the sea nettle jellyfish (Chrysaora quinquecirrha). Both species are known to frequent the coastal waters of the region.
The jellyfish in Jellyfish Lake, located in Palau, have evolved without natural predators due to the lake's isolation from the ocean. As a result, these jellyfish have lost their ability to sting, making them harmless to humans. They also have developed a unique symbiotic relationship with photosynthetic algae, providing them with nutrients through photosynthesis.
Jellyfish are members of the phylum Cnidaria. There are more than 100 kinds, each with its own Latin name. So there is no single Latin name for jellyfish.
Most jellyfish are carnivores that prey on fish, crustaceans and any other swimming animals they can subdue with their venomous stinging cells. In turn, many other animals feed on jellyfish, including tuna, crustaceans, and other jellyfish. In other words, they are both predators, and prey.
No, most jellyfish are carnivores. They primarily feed on plankton, small fish, and sometimes other jellyfish.
