Seraan (Latin: Internecivus raptus, meaning "murderous abduction"), known to Humans as Stalker, are an indigenous species found in Sye-Lyon, the neighbouring planet of Sanghelios, serving as a hunting pair to the Covenant Sangheili. The Seraan has relatively short body and long legs, with four sharp claws. The species' success in the wild rather than in lances owes in part to its opportunistic hunting behaviour, its adaptability to a variety of habitats and its ability to move at up to approximately 80 kilometres an hour. The Seraan consumes virtually any flesh it can hunt down and catch.
