The Cenderawasih epaulette shark has no hood on its head from snout to gills. These sharks have a rather elongated, slender body with a short snout, and the anteroposterior distance is less than 3% of body length. The eyes and perorbital ridges are raised. The nostrils are located at the tip of the snout. They are framed by short antennae, less than 1.3% of body length. The mouth is located in front of the eyes and is moved closer to the tip of the snout. The folds of the lower lip are not joined by a skin fold at the chin. The distance to the premaxilla is less than 13% of the body length. There are spiracles behind the eyes.
