>>Most members of the Chilobrachys spider genus have muted brown, black or grey coloring. But Chilobrachys jonitriantisvansicklei—a newly described tarantula native to Sri Lanka—defies this trend. As a trio of researchers reports in the British Tarantula Society Journal, females of the species boast brilliant blue coloring on their legs and an iridescent sheen on their hard outer shells and abdomens.
The spider, named after donor and conservationist Joni Triantis Van Sickle, measures around five inches long (Drake notes that it’s “big enough to comfortably hug a donut”) and is a speedy, aggressive predator that darts out from its underground burrow when hapless insects arrive on the scene.<<
