this Khil term describes the strands of flesh which chang from their faces. The Khil rely on their hullepi for a number of uses. Primary among them is respiration; the hullepi collect air from around them and filter it to the lungs. The second use is feeding, as the debris filtered out by the hullepi is often rich in micro-proteins and other solid matter, and is consumed by the Khil. The third use of the hullepi is for communcation. By drawing air around and through hullepi of varying lengths and thicknesses, the Khil can create a musical form of speech.
