Phylum Arthropod

Member of the Phyllum Arthropoda can be found in the seas, in fresh water, on land, or even flying freely; a group with amazing differences of structure, and so abundant that all the other animals taken together are less than 1/6 as many as the arthropods. Well-known members of this group are the lobsters, crayfish and crabs; scorpions, spiders, mites, ticks, the centipedes and millipedes; and last, but not least, the most abundant of all, the insects. The Phylum Arthropods consist of the following classes: arachnids, chilopods, diplopods, crustaceans and hexapods (insects).
