A polyp in zoology is one of two forms found in the phylum Cnidaria, the other being the medusa. Polyps are roughly cylindrical in shape and elongated at the axis of the vase -shaped body. In solitary polyps, the aboral (opposite to oral) end is attached to the substrate by means of a disc-like holdfast called a pedal disc , while in colonies ...

Polyp, in zoology, one of two principal body forms occurring in members of the animal phylum Cnidaria. The polyp may be solitary, as in the sea anemone, or colonial, as in coral, and is sessile (attached to a surface). The upper, or free, end of the body, which is …

Sea anemones are mostly solitary, but the majority of corals are colonial, being formed by the budding of new polyps from an original, founding individual. Colonies of stony corals are strengthened by mainly aragonite and other materials, and can take various massive, plate-like, bushy or leafy forms.

2025年2月24日 · What are polyp animals? Marine polyps are animals belonging to the phylum Cnidaria. They are small organisms essential to ocean ecosystems. Examples include corals, sea anemones and certain jellyfish.

The class Anthozoa (under the phylum Cnidaria) includes corals, anemones, sea pens and seafans. Anthozoa consists of 10 orders and thousands of species. Adults are attached to the seabed, but their larvae are free-floating and can drift to new settlements.

2018年9月19日 · Mactra, Cerastoderma and Spisula species are abundant in many North Sea regions and empty bivalve shells could provide an abundant settling substrate for jellyfish polyps in the North Sea and other areas. Several new strategies to increase the detection of polyps on bivalve shells are presented.

Zoanthus sociatus, commonly known as the green sea mat or button polyp, is a zoanthid usually found in shallow reef zones of tropical regions from Caribbean to southeastern Brazil. Z. sociatus is currently being studied for its use against human lymphatic parasites.

To gain insight in the distribution, species composition and population structure of scyphozoan jellyfish polyps in the southern North Sea area, polyp samples were collected from natural and artificial substrates (settling plates, marina floats and wrecks) at ten inshore locations in the Netherlands, seven offshore locations in the North Sea ...

2017年4月28日 · In the same class, Anthozoa, sea anemones also take a polyp shape for the majority of their lives. Although much bigger than individual coral polyps, the sea anemones operate in the same way. A pedal plate attaches the anemone to a hard surface, and they use their tentacles to catch food and deliver it to the mouth.

A polyp is a life stage of certain cnidarians, characterized by a cylindrical body with a mouth surrounded by tentacles at the top. This sessile form is primarily found in organisms such as corals and sea anemones, serving as one of the two main body plans of cnidarians, the other being the medusa.
