Full Answer

There are around 7,000 species that fall under the classification of echinodermata, otherwise known as echinoderms. At least 800 of these can be found in the waters that make up the Great Barrier Reef. The name "echinodermata" comes from the Greek "echinoderma," meaning "spiny skin."

Echinoderms are easy to spot because of their radial symmetry, since all echinoderm species have five arms or multiples of five arms. They also have a calcium carbonate shell covered by skin. Echinoderms have fairly rudimentary respiratory systems that allow them to take oxygen in through tube feet and simple gills.

    What are some examples of animals that migrate?

    A:

    Examples of animals that migrate include butterflies, land animals, birds and whales. Animals migrate for a wide variety of reasons, such finding food as the weather changes or mating in specific locations year after year. One of the most well known migrations is the complex, extended migration of the Monarch butterfly. The migration cycle lasts longer than the life span of one butterfly, so no single butterfly makes the entire trip from Canada to Mexico and back again.
