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
Echidnas are known better as spiny anteaters, although they are not related to them, besides that fact that both anteaters and echidnas eat ants and termites. The echidna is found in parts of New Guinea and Australia.
The echidna has a long tongue around 18cm long that can whip in and out of its mouth at incredible speeds. This helps the echidna to forage for ants an termites.
The echidna was named after a monster in Greek mythology! The echidna can dig incredibly well due to its long claws, meaning that echidna are able to escape danger by digging straight down.
The echidna is a small mammal and the echidna has a long snout that acts as both the mouth and nose of the echid

The woolly mammoth was an enormous mammal that once roamed the vast frozen, northern landscapes in large size. Believed to be closely related to the modern-day elephant, the woolly mammoth remained in the wild until roughly 1700 BC when it became extinct.
The woolly mammoth was found roaming the bitter Arctic tundra where they would often gather in large herds for both warmth and protection. Woolly mammoths lived in two groups which are thought to have been different enough to be characterized as separate subspecies. One woolly mammoth group stayed in the middle of the high Arctic, while the other woolly mammoth group had a much wider range.
