One of the most feared predators on Darwin IV, skewers count among their prey all large land animals, except the massive groveback. Their formidable hunting array includes wings spanning 50 feet and equipped with four methane-powered "jet" pods that can generate speeds up to 200 mph. A skewer uses its speed to drive the long hollow lance protruding from its head deep into its victims. Prey are then carried aloft and sucked dry. Skewers hunt in small packs and are found across 90 percent of the planet.
