The bell of the jelly blubber is spherical in shape, and its feeding structures make up a greater proportion of its body than in many other species of jellyfish. [5] Because of their unique body shape, C. mosaicus are known to utilize jet propulsion, triggered by the contracting and relaxing patterns of their bell. [5]
The middle layer is called the mesoglea; a jelly-like substance that is flexible and dense. The outermost layer is the epidermis ; it contains the nerve net. [ 4 ] There is a network of branching canals linked with the primary ring canal, but these are not joined to the gastrovascular cavity except through the sixteen or thirty two radial canals .
Polyorchis, or bell jellies, is a genus of hydrozoans in the family Corynidae. They are transparent with red coloration in their internal organs and eye spots around the rim of their bell. The red pigmentation helps them camouflage. They are often found in harbors, marinas, and other calm waters close to shore.
The bell is separated from the dangling oral arms and both are washed in seawater before being scraped to remove the gonads and mucus. Dehydration is traditionally undertaken by sprinkling the jellyfish with table salt and alum , draining off the brine and repeating the process. [ 14 ]
The large bell of the jellyfish has been proposed as used for either locomotion or feeding when closed. The Deepstaria also features a geometric mesh pattern throughout its bell; this mesh, being the gastrovascular system , delivers nutrients to the entire jelly as it stretches and contracts to move and capture prey.
The medusa of Turritopsis dohrnii is bell-shaped, with a maximum diameter of about 4.5 millimetres (0.18 in) and is about as tall as it is wide. [11] [12] The mesoglea in the walls of the bell is uniformly thin, except for some thickening at the apex. The relatively large stomach is bright red and has a cruciform shape in cross section.

This small stalked jellyfish grows up to 1 cm across and is pale and transparent. Four distinct opaque white lines run down the bell and into the mouth, which is surrounded by four horseshoe-shaped gonads. The bell has opaque white spots. Several lobes extend from the margin of the bell.
