The Scyphozoa are an exclusively marine class of the phylum Cnidaria, [2] referred to as the true jellyfish (or "true jellies"). The class name Scyphozoa comes from the Greek word skyphos (σκύφος), denoting a kind of drinking cup and alluding to the cup shape of the organism. [3] Scyphozoans have existed from the earliest Cambrian to the ...
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.
Onymacris unguicularis beetle with landmarks for morphometric analysis. In landmark-based geometric morphometrics, the spatial information missing from traditional morphometrics is contained in the data, because the data are coordinates of landmarks: discrete anatomical loci that are arguably homologous in all individuals in the analysis (i.e. they can be regarded as the "same" point in each ...

In the class Scyphozoa, the medusa stage is dominant, and the polyp stage may or may not be present, depending on the family. In those scyphozoans that have the larval planula metamorphose into a polyp, the polyp, also called a " scyphistoma ," grows until it develops a stack of plate-like medusae that pinch off and swim away in a process known ...
Hair whorls are sometimes classified according to the direction of hair growth (e.g. clockwise or counterclockwise), shape, or other physical characteristics. Anecdotal evidence claims a statistical correlation between the location, number, or type of whorls and behaviour or temperament in horses and other species.
Ribs play an important role in the shape of the chest, whether they are narrow or wide. The overall shape of a horse's chest plays a key role in the front leg movement. The horse's chest should be well defined and not blend into the neck. Width of the chest is measured from shoulder to shoulder, at the points of shoulders.
Horses with at least one Lp gene possess, at the very least, leopard-complex "characteristics": skin that is mottled, speckled or blotchy around the muzzle, eyes, genitals, and anus; the remainder of the body may be primarily pigmented (gray or black in the absence of other genes), primarily unpigmented (pink or flesh-colored), or mottled,
