- CnidocytesCnidaria is a phylum of aquatic animals that are characterized by having cnidocytes, specialized cells that fire harpoon-like structures to capture prey123. Cnidarians are mostly marine, have radial symmetry, and have two body layers separated by a jelly-like layer453. Cnidarians also have a true coelom or coelenteron, and tentacles surrounding the mouth53.Learn more:✕This summary was generated using AI based on multiple online sources.

Their distinguishing feature is cnidocytes, these are specialized cells that they use primarily for capturing prey.www.vedantu.com/animal/cnidaria
Cnidarians are distinguished from all other animals by having cnidocytes that fire harpoon like structures and are usually used mainly to capture prey. In some species, cnidocytes can also be used as anchors.
en.wikipedia.org/wiki/CnidariaCnidarians have a true coelom or coelenteron, they also have diploblastic or two level tissue organisation. Their specialized structures of stinging or nematocysts/nematoblasts help in defense. So, the correct answer is 'All of the above'.
www.toppr.com/ask/question/cnidaria-is-characteri…Cnidarians share several basic characteristics. All Cnidaria are aquatic, mostly marine, organisms. They all have tentacles with stinging cells called nematocysts that they use to capture food. Cnidarians only have two body layers, the ectoderm and endoderm, separated by a jelly-like layer called the mesoglea. Most Cnidarians have radial symmetry.sciencing.com/basic-characteristics-cnidaria-83991…Phylum Cnidaria is also known as Phylum Coelenterate. This phylum consists of radially or radially symmetrical aquatic invertebrates having unique stinging structures in the tentacles surrounding the mouth. The organisms of this species mainly belong to marine life, and hardly a few live in freshwater.www.embibe.com/exams/phylum-cnidaria/ - People also ask
WEBGreat Barrier Reef, off the coast of Queensland, Australia. The phylum Cnidaria is made up of four classes: Hydrozoa (hydrozoans); Scyphozoa (scyphozoans); Anthozoa (anthozoans); and Cubozoa (cubozoans). All cnidarians share several attributes, supporting the theory that they had a single origin.

WEBCompare structural and organization characteristics of Porifera and Cnidaria. Describe the progressive development of tissues and their relevance to animal complexity. Phylum Cnidaria includes animals that show radial or biradial symmetry and are diploblastic, that is, they develop from two embryonic layers.
WEBCnidaria is derived from a Greek word “cnidos” meaning stinging thread. These entities are characterized by the presence of cnidae. Cnidaria is a phylum under Animalia Kingdom, a classification comprising 10,000 described species, some of them are corals, sea anemones, jellyfishes and hydras.
WEBIdentify common structural and organizational characteristics of the phylum Cnidaria. Phylum Cnidaria includes animals that exhibit radial or biradial symmetry and are diploblastic, meaning that they develop from two embryonic layers, ectoderm and endoderm. Nearly all (about 99 percent) cnidarians are marine species.

WEBCnidaria 271 species Their distinguishing features are a decentralized nervous system distributed throughout a gelatinous body and the presence of cnidocytes or cnidoblasts, specialized cells with ejectable flagella used mainly for envenomation and capturing prey.
WEBCnidarians are radially or biradially symmetric, a general type of symmetry believed primitive for eumetazoans. They have achieved the tissue level of organization, in which some similar cells are associated into groups or aggregations called tissues, but …
