Ephebopus cyanognathus (Blue Fang Tarantula) MALEEphebopus cyanognathus (Blue Fang Tarantula) for sale! This is perhaps one of the prettiest spiderlings in the hobby with bright orange legs, bright blue fangs, a shiny emerald green abdomen and gold bands on the legs! As adults they get bright purple fangs, have an olive colored body and yellow bands on their legs. As slings they tend to be more arboreal and as they mature they tend to be more fossorial terrestrial. Photo credit: (spidershop. pl).
