The caudal fin is small, with the lower lobe larger than the upper. There are three bioluminescent photophores near the eyes: beneath the eye is a large, teardrop-shaped suborbital photophore that emits red light. Behind it is an ovoid postorbital photophore that emits green light; this photophore is larger in males than females.
