The cobalt blue tarantula or Cyriopagopus lividus is a species of tarantula which is in the family Theraphosidae which is native to Myanmar[1] and over the border into Thailand.[2] It was originally described as Haplopelma lividum.
Description
The cobalt blue tarantula is a medium-sized tarantula with a leg span around 13 cm (5.1 in). It is noted for its iridescent blue legs and light gray prosoma and opisthosoma, the latter of which may contain darker gray chevrons.[3][4] 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.[5] The cobalt blue tarantula is a fossorial species and spends nearly all of its time in deep burrows of its own construction.
The venom of the tarantula is not enough to kill a human, but stings can be extremely painful. In a 2001 case study from Japan, two people bitten by a pet cobalt blue taruntula reported severe pain and inflammation, which went away after several hours. One individual experienced stiffness for a few weeks after being bitten.[6] The venom contains glutamic acid, at 0.97% concentration. Histamine and adenosine were detected at 0.14% and 0.10% with the polyamine spermine noted in trace amounts at 0.002%.[7]

Habitat
Cobalt blue tarantulas inhabit the tropical rainforests of Southeast Asia,[8] where they construct deep burrows, and generally only leave them to find food.
Pets
The cobalt blue tarantula is a mainstay in the pet trade, despite being a fast and defensive tarantula with potent venom.[6] Bites from this species can result in severe muscle cramps and inflammation.[9]
