Watch giant ghost jellyfish float in the depths of the ocean

biologists From the Monterey Bay Aquarium Research Institute (MBARI), off the coast of CaliforniaTake amazing pictures of the ocean with an underwater robot camera. In the records, it is possible to see the giant ghost jellyfish (Giant Stygiomedusa) floating at a depth of more than 975 meters.

Although this animal – one of the largest jellyfish of all seas – has been seen swimming in the depths of almost every ocean in the world, with the exception of North PoleWatching this species is extremely rare.

To give you an idea, since the first time a specimen was found, in 1899, this has happened again about 100 times, nine of which have been by scientists at the Monterey Aquarium. This is explained by the fact that giant ghost jellyfish live in areas so deep that only a few humans or remote equipment can reach them.

Giant ghost jellyfish are one of the deepest predators in the oceans

Throughout history, scientists have used trawls to study deep-sea animals. According to MBARI, these nets can be effective in studying resistant animals, such as fish, crustaceans and squid, but jellyfish turn gelatinous in these traps.

MBARI remotely operated vehicles (ROVs) have allowed researchers to study these healthy animals in their natural habitat. The high-resolution – and now 4K resolution – video of the giant ghost jellyfish demonstrates fascinating details about the animal’s appearance and behavior that scientists would not be able to see in a sample captured by trawls,” the foundation explained in a statement.

According to MBARI, the giant jellyfish’s “bell” is one meter wide, and its four ribbon-shaped “mouth arms” – which release their fangs into its mouth – can grow to more than 10 metres.

A survey conducted by the institute revealed that these cnidarians are one of the most important predators in the deep ocean, competing for food with cephalopods, fish and even whales blue.
