Brazilian Jewel Tarantula (Typhochlaena seladonia)

Typhochlaena seladonia

The Typhochlaena seladonia, universally revered as the 'Brazilian Jewel Tarantula'. It is a tiny arboreal tarantula (barely 2-2.3 inches legspan) unanimously considered the Holy Grail and the most colorful and expensive spider in the world. Its entire body is an incredible fluorescent palette: black and bright pink legs, metallic blue/green iridescent carapace and a black, red and yellow mosaic decorated abdomen. Unique in its ethology: it builds tiny 'arboreal trapdoors' by detaching pieces of bark and assembling them with web on the walls of trees. Incredibly fragile, delicate and very rare in captivity, it requires very expert keepers.
