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 Dwarf Crocodile is a small species of crocodile that is natively found in the rainforests of West Africa. The Dwarf Crocodile is the smallest species of crocodile in the world and is also one of the most distinctive with a short, broad snout and tough scales that cover their entire black body (most crocodiles do not have such armoured scales on their underside). These characteristics have led to the Dwarf Crocodile being known by a number of different names including the Broad-Snouted Crocodile, the Bony Crocodile and the Black Crocodile. There are two recognised species of Dwarf Crocodile which are the West African Dwarf Crocodile and the Congo Dwarf Crocodile which differ slightly in n

The barracuda is a large species of fish found in the warmer, coastal regions of the world's oceans. There are more than 20 different species of barracuda that range in size from less than 50cm to nearly 2 meters in length.
The barracuda is widely spread across the oceans but is more commonly found in the more tropical regions where there is an abundance of food. Although barracudas can be found in the deep ocean, they tend to prefer coastal habitats along continental shelves and close to coral reefs.
Despite the difference in size and colour between barracuda species, all species of barracuda have a similar elongated appearance, and pointed head with powerful jaws, containing ro
