Tarantula - Cobalt Blue

Cyriopagopus Lividus  

The cobalt blue tarantula is a medium-sized tarantula with a leg span around 13  cm (5 in). It is noted for its iridescent blue legs and light gray prosoma and opisthosoma, the latter of which may contain darker gray chevrons. Males and females look the same until the ultimate (final) molt of the males. At this point, the male exhibits sexual dimorphism in the form of a light tan or bronze coloration and legginess. Additionally, males gain a palpal bulb on the pedipalps and tibial apophyses (mating hooks). The female eventually becomes larger than the male and lives years longer. The cobalt blue tarantula is a fossorial species and spends nearly all of its time in deep burrows of its own construction.
