Examples of cnidarian
cnidarian
Their presence implies that the cnidarian and bilaterian lineages had already diverged.

Similarities with cnidarian planula may indicate an ancestral developmental stage for metazoans.

The researchers made their discovery by studying a colonial cnidarian called Hydractinia symbiolongicarpus in the laboratory.

The similarities observed in Xenacoelomorpha hatchlings, cnidarian planula larvae and poriferan parenchyma larvae support this view.
From the nature.com
We describe a protocol for microinjection of embryos for an emerging model system, the cnidarian sea anemone, Nematostella vectensis.

Aiptasia, a familiar pest among coral reef aquarium hobbyists, serves as a valuable model organism in the study of cnidarian-algal symbiosis.
From the en.wikipedia.org
In a new article researchers describe four types of cnidarian fossils preserving traits that allow them to be related to modern orders and families of jellyfish.
From the sciencedaily.com
This absence precludes the current cnidarian method of feeding, so Seilacher suggested that the organisms may have survived by symbiosis with photosynthetic or chemoautotrophic organisms.
From the en.wikipedia.org
Further studies on Xenacoelomorpha development and comparisons with cnidarian and deuterostome species are essential to determine whether its direct development is an ancestral or a derived feature.

- Coelenterate: radially symmetrical animals having saclike bodies with only one opening and tentacles with stinging structures; they occur in polyp and medusa forms
- (cnidaria) hydras; polyps; jellyfishes; sea anemones; corals
- Cnidaria (with a silent c) is a phylum containing over 9,000 species of animals found exclusively in aquatic and mostly marine environments. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. ...
- (Cnidaria) a taxonomic phylum, within superphylum Radiata - the corals, hydra, jellyfish etc
- (CNIDARIA) The phylum of exclusively aquatic, invertebrate animals characterized by radial symmetry, a sac-like internal cavity and nematocysts stinging cells. There are four major groups of cnidarians: The Anthozoa include the corals, sea pens, and anemones. ...
- (Cnidaria) Phylum which includes very primitive, carnivorous animals with stinging tentacles. Cnidarians may appear as a sessile polyp (as seen in hydroids and sea anemones) or as a floating medusa (as characterized by jellyfish). ...
- (Cnidaria) Tissues, Radial symmetry, no body cavity, no circulatory system, nerve net/body sensors; stinging, tentacles, gastrovascular cavity
- (Cnidaria) e.g. Hydra sp. Diploblastic, acoelomate organisms with radial symmetry. Gas exchange takes place by diffusion over the whole body surface, and transport to all cells is by simple diffusion (sufficient because these are small organisms with a large S.A. to volume ratio)
- Main group of soft-bodied animals such as Jellyfish.
