A killspike referred to a species of bird indigenous to the jungle-moon called Nallastia.
These birds, known for their lack of intelligence and remarkably tough, scale-like skin, were known to travel in groups, maintaining a low altitude.
In 23 BBY, Anakin Skywalker, at the young age of 18, came dangerously close to experiencing this firsthand when he was piloting a Nallastian V-wing shuttle during a mission to Fondor. These "winged reptiles" could inflict significant damage to ships flying at lower altitudes.
