Grammostola sp.


Tarantulas (as the term is used in North America) comprise a group of often hairy and very large arachnids belonging to the family Theraphosidae, of which approximately 900 species have been identified. The sizes range from as small as a fingernail to as big as a dinner plate. Depending on the species, the body length of tarantulas ranges from 2.5 to 10 centimetres (1 to 4 in), with 8–30-centimetre (3–12 in) leg spans. The majority of North American tarantulas are brown. Most tarantulas are harmless to humans, and some species are popular in the exotic pet trade. All tarantulas are venomous, but only some species have venom that, while not known to have ever produced human fatalities, can produce extreme discomfort over a period of several days.


See in the grounds of the Shambala Meditation Center in the mountains an hour north of Fort Collins, Colorado.

thanks asergio... this one was tame,kept at the Butterfly Pavillion in Denver, Colorado.

According to this article, CSU says there are 3-5 species in Colorado. I think this one looks like the Texas brown tarantula but that's just a guess.
