Tarantulas come in almost every conceivable color, from dull
brown or black to red, yellow, metallic green or bright blue. It
all depends on the species of tarantula. Some of the most visually
stunning tarantulas are the Poecilotheria genus (and more
specifically, the Poecilotheria metallica) and the Avicularia genus
(the Avicularia versicolor has amazing colors!).
