Accessed An aquatic biome consisting of the open ocean, far from land, does not include sea bottom (benthic zone). The reason for this phenomenon is unknown, but based on current research, it has been hypothesized that mature medusae die after gamete release, which then causes them to strand. The lifespan of a jellyfish depends on the species. The dominance switch from fish to jellyfish has a negative impact on the fishing industry. Temperature and food supply could play a role in causing this difference, although further research is needed to assess these claims.

The aboral surface of the bell can be various shades of brown and has V-shaped markings around a central spot. (Fish and Fish, 1989; Houghton, et al., 2007), Compass jellyfish swim using movements of their bell to pump water and propel them forward. Individuals are solitary and generally remain near the surface of marine waters in coastal pelagic regions, although they have been documented to make extensive vertical movements through the water column over periods of several hours. It is likely that chemicals are the main means by which these jellyfish would communicate, but as they are largely solitary animals, their communication has yet to be thoroughly studied.
