Selkath

The Selkath were a species of aquatic beings. At least one Selkath called the planet of Manaan his homeworld. Because of the Selkath's water-dwelling nature, their chest armors were fitted with misting vents in order to keep their skin moist. Historically, the Selkath were devoted to preserving their native oceans and taking care of the ill. For that reason, other species regarded them as a peaceful and helpful people. However, at the time the Clone Wars, Selkath such as Chata Hyoki and Mantu brought shame to their people's reputation by working as bounty hunters.
