The eyes, which are highly reflective, are triangular (or almond-shaped) and are angled upwards from the inner to outer corners with dark eye rims. Eye color ranges from dark amber to dark brown. Their eyes exhibit a bright green glow when lights are shone on them in low light conditions. There are two features which researchers believe allow New Guinea singing dogs to see more clearly in low light. One is that of their pupils, which open wider and allow in more light than in other dog varieties. The other is that they possess a higher concentration of cells in the tapetum.
