Spiders - The cobalt blue tarantula (Haplopelma lividum)

The cobalt blue tarantula is a medium size tarantula with a leg span of approximately 13 cm (5"). The cobalt blue tarantula is noted for its iridescent blue legs and light gray prosoma and opisthosoma, the latter of which may contain darker gray chevrons.[1] Males and females look the same until the ultimate (final) molt of the males. At this point the male will exhibit sexual dimorphism in the form of a light tan or bronze coloration and legginess. Additionally males will gain embolus on the pedipalps and tibial apophysis (mating hooks). The cobalt blue tarantula is a fossorial species and spends nearly all of its time in deep burrows of its own construction.
