Discussion
- males are assumed to differ from females by E_Hp only
Facts
- aplacental viviparous, smallest shark (Ref: inaturalist)
- upper continental slope at a depth of 283-439 m (Ref: inaturalist)
- dark brown with a striking and distinctive pattern of black markings on its ventral surface, a continuous or broken, fine black line along the middle of its back; Some of the ventral black markings are composed of light-producing photophores, while others (including the patch behind the pelvic fins) are composed of pigment-containing chromatophores. (Ref: inaturalist)
