One of the feeding or nutritive zooids of a hydroid or coral.
One of the Anthozoa.
Same as Anthozoa. See Anthozoa, Madreporaria, Hydroid.
The larval stage of Cnidarians
the sessile form of the cnidarian body plan. Example: Hydra
an individual of a colonial animal such as in corals.
a small sea animal with a tubular body and a round month surrounded by tentacles. Coral is an example of a polyp.
simple animal classed as a cephalopod and attached to a seafloor substrate; e.g. anemones, corals
The living animal of a coral.
A polyp is the living unit of a coral. It also refers to the sessile stage in the life history of certain members of the phylum Coelenterata (Cnidaria).
the sedentary stage of the life cycle of cnidarians jellyfish, anemones, and corals. Made up of a cylindrical body cemented at one end to a substrate, with a mouth surrounded by a ring of tentacles at the other end.
The sessile, asexual stage in the life cycle of most cnidarians.
one of two forms that coelenterates take e.g. a hydra or coral: usually sedentary and has a hollow cylindrical body usually with a ring of tentacles around the mouth
a can-like body with a single opening leading to the stomach, surrounded by a ring of tentacles
a tubular organism closed at one end with a mouth surrounded by tentacles at the other end
a tubular, saclike animal with a mouth surrounded by tentacles
a vase-shaped, sedentary body plan, in which the mouth is directed upward
see Coral Polyp
A tiny, tubelike marine animal of which live coral is made, one end of which is attached to the sea bottom, to rocks, or to one another and the opposite end of which is a mouth surrounded by fingerlike, stinging tentacles
POL-ip The sessile form of a cnidarian. 517
The asexual reproducing, normally sedentary form of coelenterates such as the sea anemone.
sedentary form of aquatic animal.
A coelenterate having a hollow cylindrical body closed at one end and opened at the other with a central mouth surrounded by tentacles armoured with nematocysts
In cnidarians, a polyp is an animal with a cylindrical body which is attached at one end. The other end has a central mouth surrounded by tentacles. A sea anemone is a large, solitary polyp. A coral is made up of many small polyps that are structurally joined to one another as a colonial animal. A sea anemone is a solitary polyp A coral is a colony of many small polyps joined to one another
The cylindrical, typically attached stage of cnidarians (animals such as jellyfish, sea anemones, sea pens and hydroids). An individual polyp has tentacles to catch prey, a mouth, digestive tract and primitive nervous system.
The sessile form of life history in cnidarians; e.g., the freshwater hydra.
soft-bodied adult form of a member of the Cnidaria ( corals, jelly fish and sea anemones) which has a cylindrical body which is anchored down at one end. At the other end is a mouth, usually surrounded by grasping tentacles used for feeding. The young are often free-swimming medusoids. Jellyfish are free-swimming and remain in the medusoid form throughout their lives.
Typically sedentary soft-bodied component of Cnidaria (corals, sea pens etc), which comprise of a trunk that is fixed at the base; the mouth is placed at the opposite end of the trunk, and is surrounded by tentacles.
a spheroidal mass that protrudes upwards or outwards from a normal surface. Polyps may be hyperplastic, inflammatory, or neoplastic. e.g. pedunculated polyp - a polyp attached by a thin stalk ( peduncle). e.g. sessile polyp - a polyp with a broad base ( sessile).
In zoology, a polyp is one of two forms of individuals found in many species of cnidarians. The two are the polyp or hydroid and the medusa. Polyps are approximately cylindrical, elongated on the axis of the body.
A polyp is an abnormal growth of tissue (tumor) projecting from a mucous membrane. If it is attached to the surface by a narrow elongated stalk it is said to be pedunculated. If no stalk is present it is said to be sessile.
