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 avocet is a type of wading bird that is found across mudflats in the world's warmer climates. There are four different species of avocet which are the Pied avocet, the American avocet, the Red-necked avocet and the Andean avocet.
The avocet is generally found in watery habitats close to the coast including marshland, wetlands and swamp. The exact habitat of the avocet is dependent on the species as the Pied avocet is found in Europe and Asia, the American avocet is found on the Pacific coast of North America, the Red-necked avocet in Australia and the Andean avocet is natively found nesting high up in the Andes Mountains.
The avocet is a very distinctive looking bird due to t

The millipede is a medium to large sized invertebrate that is found under rocks and in decaying logs all around the world. The millipede has a long and narrow body which is made up of segments.
The millipede is from the same family as the centipede, but the millipede generally has more legs for it's body length than the centipede. The average millipede has between 80 and 400 legs, not a thousand as the name suggests.
The millipede is found all over the world but is more common in the southern hemisphere where the millipede has been known to get to nearly 40cm long. Some species of millipede have a poisonous bite which they use to kill their prey before eating it.
