Aphonopelma eutylenum, commonly called California ebony tarantula
The body of the California ebony tarantula comes in various brown tones, ranging from light beige to dark brown and ebony colors. Adult females can reach a legspan of up to 13 cm (5 inches) and live to about 25 years of age. Males reach maturity after 8–12 years and leaves their burrows after that in search of a mate. After spending all their energy on finding a suitable partner, they will die of exhaustion about 6 months after reaching adulthood.
