These half human-size predators inhabit the treetops in mature pocket forests on Darwin IV. An extremely active animal, the daggerwrist uses its dagger-tipped forearms to swing from branches, but can also take to the air using glide membranes that deploy when its limbs are extended outward. Its diet consists mostly of trunk suckers. Daggerwrists possess a complex pseudo-jaw that features a heavily-muscled tube tipped with a barbed mandible; this tube extends out to probe for prey in a snake-like fashion.
