CLASS SCYPHOZOA Meaning and
Definition
-
Class Scyphozoa is a taxonomic class within the phylum Cnidaria, which comprises aquatic invertebrates commonly known as true jellyfish. Members of this class are characterized by their bell-shaped body and the presence of stinging cells called nematocysts.
The body structure of class Scyphozoa consists of a gelatinous mesoglea, sandwiched between the two layers of epidermis and gastrodermis. This medusoid form typically displays a radially symmetrical body plan, with numerous tentacles extending from the bell's margin. The tentacles are covered with specialized cells called cnidocytes, which contain the nematocysts capable of injecting venomous toxins into their prey or potential threats.
Class Scyphozoa exhibits a wide range of species, varying greatly in size and coloration. They can be found in marine environments worldwide, from the surface waters to the deep sea. Certain species undergo complex life cycles, involving both a medusa stage and a polyp stage. The medusae are typically free-swimming, whereas the polyps attach themselves to substrates such as rocks or other surfaces.
These organisms primarily feed on small planktonic organisms, but larger species may also consume small fish and other invertebrates. They play a significant role in marine ecosystems as both predators and prey, contributing to the balance of the food chain.
In conclusion, class Scyphozoa encompasses a diverse group of marine invertebrates known as true jellyfish. These bell-shaped creatures possess stinging cells, exhibit radial symmetry, and are crucial components of marine ecosystems.

Etymology of CLASS SCYPHOZOA
The word "Scyphozoa" is derived from the Greek words "skyphos", meaning "cup", and "zoa", meaning "animals". The name refers to the morphology of the medusa stage in this class of animals, which includes jellyfish. The shape of their bell or umbrella-like body resembles a cup or bowl, and the tentacles extend downward from it, giving it a cup-like appearance. Therefore, "Scyphozoa" can be interpreted as "cup animals" in reference to their distinctive morphology.
