Deepstaria Jellyfish and Isopod Relationships

The video introduces Deepstaria, a unique jellyfish often mistaken for a plastic bag due to its appearance. It lacks typical jellyfish tentacles, instead having a large, delicate bell. Deepstaria belongs to the ancient Ulmaridae family and is an ambush predator. It has a symbiotic relationship with the giant isopod Anuropus, which lives inside it.
