Centruroides
bark scorpion, bark scorpions
Centruroides is a highly speciose genus of buthid scorpions comprising at least 100 species distributed throughout the southern United States, Mexico, Central America, the Antilles, and northern South America. Commonly known as bark scorpions, members of this genus are notable for their strong fluorescence under ultraviolet light—except immediately after moulting—and several species possess venom potent enough to cause human fatalities. The genus includes species adapted to diverse habitats ranging from tropical rainforests to arid regions, with some showing marked intra-domiciliary tendencies in urban environments.
