The striped bark scorpion (Centruroides vittatus) was first described by the American naturalist and entomologist Thomas Say (1787 — 1834) in 1821. This scorpion, and all other scorpion species, are arthropods (invertebrate animals with jointed appendages) in the class Arachnida — first described in 1812 by the French naturalist and zoologist Jean Léopold Nicolas Frédéric Cuvier (1769 – 1832) using the Greek noun ἀράχνη, aráchnē = “spider” — and the order Scorpiones. That order, which in early 2011 contained about 1,750 recognized species, was first described by the German entomologist and arachnologist Carl Ludwig Koch (1778 — 1857), using the Greek noun σκορπιος, scorpios = “scorpion.” [...]
