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
Bull sharks are mainly found in the warmer and shallower coastal waters of the southern hemisphere. The bull shark is one of the most common species of shark found worldwide.
The bull shark is able to inhabit both salt and freshwater sources just as happily, with one bull shark known to have swum 4,000 km up the Amazon River in South America, finally ending up in the mountainous Peru.
The bull shark is well known for its unpredictable and aggressive temperament and is thought to be one of the most dangerous sharks towards humans. This is probably because the bull inhabits coastal waters and rivers and is therefore more likely to come into contact with swimmers and water sports en

The Giraffe is a long-necked, hoofed mammal that is natively found grazing in the open woodlands of sub-Saharan Africa. The Giraffe is the tallest living animal on land and despite it's height is mostly closely related to the much smaller and solitary Okapi, that is found elusively dwelling in the dense tropical forests. There are nine recognised sub-species of Giraffe that are found in differing geographic locations and vary somewhat in the colour and pattern of their spot-like markings. Although the Giraffe would have once been found across sub-Saharan Africa and even in parts of North Africa, today they are extinct from much of their historically vast natural range with only small, isolat
