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 .
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.
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.
Bloodybelly comb jelly (Lampocteis cruentiventer) swimmingThis ctenophore differs from all previously described lobate ctenophores in two major ways: (1) all of the meridional canals have blind aboral endings, and (2) the body is penetrated by a deep notch located between the adjacent subtentacular comb rows at the level of the infundibulum.

Phyllorhiza punctata is a species of jellyfish, also known as the floating bell, Australian spotted jellyfish, brown jellyfish or the white-spotted jellyfish. It is native to the western Pacific from Australia to Japan, but has been introduced widely elsewhere.
Although it is similar to the lion's mane jellyfish, the blue jellyfish is not as large, and has a translucent bell. [ 1 ] C. lamarckii has a blue or yellow tone and grows to approximately 10 to 20 cm (3.9 to 7.9 in) across the bell, but specimens can grow to 30 cm (12 in). [ 2 ]
