**Kremarapax mckinleyi**

***Kremarapax mckinleyi*** (lit. "McKinley's hanging snatcher") is a species of aspidont.

## Description

With mature specimens of the species measuring about sixty centimeters long and possessing a characteristic dull, striped hide, *K. mckinleyi* was among the first aspidont species to evolve. Members of this species are prolific ambush predators residing in the understory and canopy of the eastern tropical rainforest, and are specialized for catching flying prey like the opisthopterans and pleuropterans.

When hunting, an member of *K. mckinleyi* positions itself on the underside of a tree branch and waits patiently for prey to fly near. While waiting, the aspidont has its hind limbs grip the branch, and has its forelimbs grip the animal’s rear section, bending the creature’s body into a tight curve. When a potential meal draws near, the aspidont releases its forelimbs and drops downward to intercept the victim’s path and snatch it out of the air. The predator subsequently injects a potent venom into its catch, and restrains the animal with its powerful forelimbs until the venom can take effect.

## Notes

* *Kremarapax mckinleyi* was named in honor of patron Zachary McKinley.
