The velvet dogfish, Zameus squamulosus, the only member of the genus Zameus, is a harmless sleeper shark of the family Somniosidae, found around the world between latitudes 64°N and 48°S, from the surface to 2,000 m. Its length is up to 84 cm.[1] Although sharks within the family Somniosidae have generally been accepted to be non-luminous, Zameus squamulosus has photophores on its ventral epidermis. [2]

Reproduction is ovoviviparous.
