Coral
CORAL
,Noun.
1.
In zoology, a genus belonging to the order of vermes zoophyta. The trunk is radicated, jointed and calcarious. The species are distinguished by the form of their branches, and are found in the ocean adhering to stones, bones, shells, &c. Coral was formerly supposed to be a vegetable substance, but is now known to be composed of a congeries of animals. Coral is red, white and black. It is properly the shells of marine animals of the polype kind, consisting of calcarious earth combined with gelatine and other animal matter. In the South Sea, the isles are mostly coral rocks covered with earth. Corals seem to consist of carbonate of lime and animal matter, in equal proportions.2.
