The Cobalt Blue Tarantula is one of the more beautiful, yet one of the more aggressive species of tarantula. The Cobalt Blue Tarantula looks almost black at a glance, but upon closer inspection, with certain lighting, this species shows a bright blue overall colour! These tarantulas are very popular, but aren't good for beginners. Cobalt Blue Tarantulas are extremely aggressive and fast. Even the spiderlings of this species have been known to show aggression! The Cobalt Blue Tarantula is uncommon in the wild, but is becoming more and more familiar in captivity. These tarantulas spin large webs even though they do spend most of their time in their burrow if given the opportunity. The Cobalt Blue Tarantula is an amazing tarantula for anybody who dares to keep it!
