Colombian Giant Redleg (Megaphobema robustum)

Megaphobema robustum

The Megaphobema robustum, imposing 'Colombian Giant Redleg'. It is a titanic and stocky Andean terrestrial (5.9-7.9 inches legspan, incredibly massive). Loved for the violent contrast of its body: a velvety black carapace that clashes with legs and abdomen of a Salmon Orange or bright Brick Red color. Presents one of the most bizarre and fascinating defensive methods: if threatened, it rotates in a circle or hops ('cartwheel defense') whipping the air with the powerful hind legs equipped with sharp spurs. Loves cool temperatures, asphyxiating humidity and does not tolerate domestic heat.
