what does coral means?

Question

what are corals

Answer 1

Corals are marine animals of the class Anthozoa, which include sea anemones (order Actiniaria). Corals are gastrovascular marine cnidarians (phylum Cnidaria) and exist as small sea anemone-like polyps, typically in colonies of many individuals. The group includes the important reef builders known as hermatypic corals, found in tropical oceans, and belonging to the subclass Zoantharia of order Scleractinia. The latter are also known as stony corals since the living tissue thinly covers a skeleton composed of calcium carbonate. A coral "head" is formed of thousands of individual polyps, each polyp only a few millimeters in diameter. The colony of polyps function as a single organism by sharing nutrients via a well-developed gastrovascular network. Genetically, the polyps are clones, each having exactly the same genome. Each polyp generation grows on the skeletal remains of previous generations, forming a structure that has a shape characteristic of the species, but also subject to environmental influences.

Answer 2

A rocklike deposit consisting of the calcareous skeletons secreted by various anthozoans. Coral deposits often accumulate to form reefs or islands in warm seas.
Any of numerous chiefly colonial marine polyps of the class Anthozoa that secrete such calcareous skeletons.
The red-orange, pinkish, or white deposits secreted by corals of the genus Corallium, used to make jewelry and ornaments.
An object made of this material.
A deep or strong pink to moderate red or reddish orange.
The unfertilized eggs of a female lobster, which turn a reddish color when cooked.

Answer 3

There is the marine animal that makes the reefs, and there is the orange color of coral. Coral also refers to the reefs that the coral made.
