Old World vultures are vultures which are found in the Old World, i.e. the continents of Europe, Asia and Africa, and which belong to the family Accipitridae, which also includes eagles, buzzards, kites, and hawks.
Old World vultures are not closely related to the superficially similar New World vultures and condors, and do not share that group's good sense of smell. The similarities between the two groups of vultures are due to convergent evolution rather than a close relationship. They were widespread in both the Old World and North America, during the Neogene. Old World vultures are probably a polyphyletic group within Accipitridae, with palm-nut vulture, Egyptian vulture and lammer
The burrowing frog is a large sized species of frog that is natively found in Australia. Burrowing frogs are most commonly found in their burrows in river banks and close to marshes, streams and lakes.
There are six different species of burrowing frog in Australia which vary in size from around 6cm to 10cm long. Only one of the six species of burrowing frog is found in south-eastern Australia, as the other five burrowing frog species are all found in western Australia.
The burrowing frog has a very distinctive appearance and is easily identified by its large, bulging eyes, short body and long legs and toes. Unlike many other species of frog, the toes of the burrowing frog are not

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
