Horsetail was named for its bristly appearance. The genus name Equisetum is derived from the Latin words equus, meaning horse, and seta, meaning bristle. Other names for horsetail include shave-grass, bottle-brush, and paddock-pipes.
There are over 800,000 named species in the Phylum Arthropoda, named from the Greek arthros (= jointed) and poda (= foot), including the familiar arachnids, crustaceans, and insects, together with a host of less familiar critters, like centipedes, millipedes and sea spiders. All arthropods have jointed appendages.rthropods excrete by means of malphigian tubules, projections of the digestive tract that help conserve water. Terrestrial forms excrete nitrogen as uric acid, as do birds. Their waste is nearly dry, a superb adaptation to life on land. Arthropods have an open circulatory system, and separate sexes.
