They also possess energy weapons which fire a red energy pulse that stuns the target for a short time, and use hibernation pods to hold their kind in stasis for long periods. They appear to be fairly advanced, possessing large spaceships such as those encountered by Destiny. They are rather nimble, able to leap off walls and crawl on all fours with surprising speed. They are capable of breathing the same atmosphere as humans. They appear to have an exoskeleton, like insects, and have thin, bony fingers. The Ursini are bipedal, like humans, but are shorter than an average human by at least a foot.
