Marine Biologists from the Monterey Bay Aquarium Research Institute (GOOD, for its acronym in English) managed to record a giant ghost jellyfish (вЂStygiomedusa giganteaвЂ™) that floated 990 meters deep in Monterey Bay, California (USA).
This is an extremely rare encounter, as this creature has been seen by MBARI experts only nine times, including this one, and only a hundred sightings are recorded worldwide.вЂњThe giant ghost jellyfish was captured for the first time in 1899. Since then, scientists have only come across this animal about 100 timesвЂњ, he claimed the institute, explaining that sightings are so rare because this animal generally swims in waters too deep for human or remote submarine access. It wasnвЂ™t until 60 years later that it was recognized as a new species.
The giant ghost, which is among the largest jellyfish on the planet, has been seen in the deepest parts of all the worldвЂ™s oceans except the Arctic.Its bell measures more than a meter wide, and its buccal arms are ribbon-shaped they can grow up to more than 10 meters long. Despite having little information about this animal, scientists they think that its вЂњmouth armsвЂќ, which flow as it passes, serve to catch prey and bring them to the mouth.
Before the advent of remotely controlled submarines, scientists captured these deep-sea creatures with the help of trawls, a method that is not very suitable for jellyfish.вЂњThese nets can be effective for studying resistant animals such as fish, crustaceans and Top Site Info squid, but jellyfish turn into a sticky, gelatinous substance in trawls. Cameras in MBARIвЂ™s remotely operated vehicles have enabled the researchers by MBARI study these intact animals in their natural environmentвЂњnoted the biologists.
