Mosquitoes’ Locomotion and Painless Piercing

Some 10 million different species of animals and plants are known to exist on earth Of which, arthropods make up the largest category with roughly 5 million species. The word, arthropods, is derived from two Greek words: arthron (joint) + podos (foot), meaning jointed feet. These are spineless animals with segmented bodies, paired and jointed legs, exoskeletons, and bilateral symmetry. Arthropods, being one of the major class of animals, create medical problems. They attack other organisms, cause allergic reactions, release toxins and venoms, and may even cause death.
