Corals are marine invertebrates in the class Anthozoa of phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. The group includes the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.
A coral "group" is a colony of myriad genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in length. A set of tentacles surround a central mouth opening. An exoskeleton is excreted near the base. Over many generations, the colony thus creates a large skeleton that is characteristic of the species. Individual heads grow by asexual rep

The Black Bear (also known as the American Black Bear) is a medium sized species of bear that is found inhabiting a variety of forested habitats across North America. The Black Bear is not only the most widespread bear on the North American continent but it is also the most numerous bear species in the world with there thought to be double the number of Black Bear individuals than all the other species put together. The Black Bear is also one of the only two out of the eight bear species that is not listed by the IUCN as being endangered as extensive conservation efforts added to their versatility has led to healthy populations throughout much of their remaining natural range (providing that
