I thought up the Nigrahm species in writing for a thread of the boundless world of NEX, a group at Onelist, of egroups. They dwell in the forest of Sedran, roaming and hunting during the hours of twilight and dusk. Dominated by Queen Sscashii, the Nigrahm speak a tongue of hissing and barks, as well as (for some) a broken form of (what I guess you could call) Basic. The little oval on the cheek is a biolight pad, used in communication, aiding to identify members of the tribe, and in religious ceremonies. The tail is long and supple, and often used as a whip in combat. They are able to climb somewhat, but only on solid surfaces up to 90 degrees, such as trees, with plenty of holds. You can read the story at the archives.
