Colombian Lesserblack Tarantula (Xenesthis immanis)

Xenesthis immanis

The Xenesthis immanis, known as 'Colombian Lesserblack Tarantula'. A magnificent and gigantic creature (7.1-8.7 inches legspan), considered the Holy Grail of South American terrestrials for its psychedelic coloration. The abdomen and legs are deep black, but the carapace explodes in a dazzling and iridescent purple, magenta or metallic 'starburst' pink. Nervous, voracious and fast growing, it requires huge tropical terrariums. Curiously known in nature for its rare mutualism with Microhylidae frogs, which protect its eggs from ants in exchange for shelter.
