Mexican red-kneed tarantulas are docile spiders with black bodies that boast orange coloration at the joints of their legs. Thier upper shell is tan and dark. They are large, thick spiders that can live up to 20 years.


Tarantulas are among the largest spiders, some of which reach a leg-spread of up to 10 inches. They are found in a variety of habitats including deserts and woodlands.

Though painful, the bite of the tarantula is rarely fatal to humans.
