Night on the ground on Skull Island is a dangerous time and place to be if you are small. Among the invertebrate predators, few have jaws that can compete with those of the moonspider. A variety of sun spider, not a true spider, the ten-legged moonspider sports huge crushing mandibles and paralytic venom to make short work of its prey. Rodents, lizards, small ground birds, and even non-avian dinosaur chicks are potential victims. A bite from the sizable arachnid can cause significant discomfort to even an adult dinosaur. Moonspiders hunt at night to avoid becoming prey to diurnal birds and other large hunters.
