Cobalt blue tarantula
Template:Short description Template:Speciesbox
The cobalt blue tarantula or Cyriopagopus lividus is a species of tarantula which is in the family Theraphosidae which is native to Myanmar<ref name=WSC_s37470/> and over the border into Thailand.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It was originally described as Haplopelma lividum.
Description
The cobalt blue tarantula is a medium-sized tarantula with a leg span around Template:Convert. It is noted for its iridescent blue legs and light gray prosoma and opisthosoma, the latter of which may contain darker gray chevrons.<ref>Photos of Haplopelma lividum</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> 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.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> 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 it can badly sting them and be extremely painful. 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% (Moore et al., 2009).

Habitat
Cobalt blue tarantulas inhabit the tropical rainforests of Southeast Asia,<ref>Template:Cite journal</ref> 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.<ref>Template:Cite journal</ref> Bites from this species can result in severe muscle cramps and inflammation.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
