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 ferret is a domestic animal thought to be native to Europe. The ferret is thought to be a subspecies of polecat and the ferret has the same long shaped body as a polecat and a weasel.
The ferret is thought to have been domesticated around 2,500 years ago, which is roughly the same time that a number of animals such as the donkey and goat were put to domestic use. The ferret is used to help farmers hunt out rabbits and the ferret does this by crawling into the rabbit burrows, with the ferret using its incredibly shaped flexible body to its advantage as a ferret is often small than many rabbits. The rabbit is scared out of the burrow by the invading ferret and uses one of the many bu

Catfish are a group of bottom-feeding fish that are found in freshwater habitats and coastal regions on and around every continent in the world with the exception of Antarctica. Catfish are most easily identified by their flattened broad heads and the long whisker-like barbels that protrude from the mouth of the catfish.
The long barbels of the catfish contain the taste buds of the catfish and so are often most commonly used for smelling and therefore sensing what is about to eat (and to hide from) in the surrounding waters. Despite the name however, not all catfish species have prominent whisker-like barbels.
There are nearly 3,000 known species of catfish in the world but it is
