Deepstaria: A Giant Deep Sea Jelly That Houses A Tiny Isopod Pal

deep staria It looks like a combination of a ghost emoji and a floating plastic bag, but don’t underestimate this shape-shifting jellyfish. It is one of the largest and strangest deep-sea invertebrate predators.

There are two recognized species; deep stariaD. enigmatic and D. reticulum – Named after the US research submarine Deep Star 4000, which first discovered the genus in the 1960s.

In classification genealogy, they are part of a class called . Cyphozoa, usually called real jellyfish. but, deep staria It has some major differences from other jelly relatives.

Jellyfish usually have thin tentacles with relatively small bells; deep staria is the opposite, with very small tentacles and a large bell that extends like a parachute.vast bell deep staria It features a unique geometric mesh pattern, which is a passageway for the gastrovascular system that transports nutrients throughout the body.

Many jellyfish live in groups called schools or shoals because they tend to get caught up in ocean currents; deep staria They look like lone rangers living in relative solitude in the dark depths of the ocean’s abyss.

This jellyfish lives in the deep waters of the world’s oceans between 600 and 1,750 meters (1,968 and 5,741 feet) deep. This part of the ocean is known as the Midnight Zone because it has little or no natural light and is characterized by cold, salt water around 4°C (39°F).

In 2018, scientists observed a rare creature. D. enigmatic It was located near Mexico’s Pacific coast and reportedly measured 68.3 x 55.7 centimeters (approximately 27 x 22 inches). It seems to be a relatively large individual, deep staria Jellyfish are large predators of deep-sea invertebrates.

One of the most notable observations was made in 2019, when scientists aboard the EV Nautilus research vessel captured video footage of Earth (above). deep staria Jellyfish at the Pacific Islands Marine Monument.

Amidst the many “wows” and “ooohs”, the researchers noticed a red isopod living inside the blanket-like bell. It is unclear whether this relationship is symbiotic (both parties benefit from the alliance) or parasitic (a one-sided friendship that benefits only the isopods).

Isopods are protected from predators inside the jellyfish bell, and are likely to receive nourishment from within their bodies, but it is unclear how the jellyfish benefit from this. Nevertheless, small crustaceans and other creatures are often found living inside the bell. deep stariasuggesting that this unlikely bond runs deep.
