The Columbian Giant Tarantula is a very beautiful, large, and unusual tarantula. They are a very popular species for advanced collectors, but they can get expensive. Columbian Giant Tarantulas are known for their unusual defensive behaviours. These tarantulas are of course able to flick urticating hairs and bite, like the usual New World tarantula species, but wait... there's more. They will stretch out their legs, and bob up and down as a first effort to scare away or intimidate the predator. If that doesn't work, then Columbian Giant Tarantulas will then spin in a circle while whipping their legs around trying to hit the predator with the sharp spikes on their back legs. The Columbian Giant Tarantula is an amazing tarantula species like no other!
