In order to appreciate them better, you will probably want to know a little bit more about them, and whether or not they could possibly be harmful.
Invertebrates are the animals without backbones and are the largest group of animals in the world.
Arthropods are the most extensive phylum in the animal kingdom, composed of more than three fourths of all known species. There are approximately 900,000 species of arthropods that have been recorded, and many more remain yet to be classified. Arthropods are more widely distributed throughout all regions of the earth than are members of any other phylum. They are found in all environments, from ocean depths to very high altitudes, and from the tropics to both polar regions. Arthropods have adapted to survive on land, in the air, and in fresh, brackish and marine waters.
