Definition of Scyphozoa in English:

Scyphozoa

plural nounˌsʌɪfəˈzəʊəˌskɪfəˈzəʊəˌskʌɪfəˈzəʊəˌsīfəˈzōə

Zoology

A class of marine coelenterates which comprises the jellyfishes.
Example sentencesExamples
- The Scyphozoa, or jellyfish, are an exclusively marine class in which the medusoid stage dominates.
- The phylum has traditionally been divided into four classes (Anthozoa, Scyphozoa, Hydrozoa and Cubozoa) distinguished by variation in these life cycle characteristics.
- Fission is typical in many anthozoans as well as in Hydrozoa and Scyphozoa, so it is reasonable to hypothesize that the cellular and molecular mechanisms involved may be similar among all cnidarians.
- Originally grouped as an order within the class Scyphozoa, the Cubozoa were elevated to class status once research revealed the magnitude of the differences between this and other cnidarian groups.
- The groups Hydrozoa, Scyphozoa and Cubozoa all are generally characterized as having polyps and medusae (although minor lineages have lost medusae and in some cases polyps).
- Most hydrozoans show the same alternation between polyp and medusa phases that the Scyphozoa, or ‘true’ jellyfish, have.

scyphozoan

adjective & noun

Zoology

An alternative interpretation is that C. striata preserves the episodically elongating organic sheath of a budding scyphozoan.
Example sentencesExamples
- Moore and Harrington regarded Sphenothallus as a hydrozoan or scyphozoan.
- Sphenothallus Hall, 1847 is a widespread Paleozoic marine taxon that has been interpreted most recently as a tubiculous annelid or other ‘worm’ or as a thecate hydrozoan or scyphozoan cnidarian.
- Jellyfish (medusae, which may be hydrozoan, scyphozoan or cubozoan) are important both as predators and prey in pelagic ecosystems.
- As mentioned above, a few tetraradial ‘medusoids’ could be scyphozoan jellyfish, but tetraradial symmetry is also typical of the Hydrozoa and Cubozoa.
- Most hydrozoans alternate between a polyp and a medusa stage - they spend part of their lives as ‘jellyfish’ which are hard to distinguish from scyphozoan jellyfish.

Origin

Modern Latin (plural), from Greek skuphos 'drinking cup' + Greek zōion 'animal'.
