The velvet dogfish (Zameus squamulosus), the only member of the genus Zameus, is a small sleeper shark of the family Somniosidae, found around the world between latitudes 64°N and 48°S, from the surface to 2,000 m.
Description
[edit]Its length is up to 84 cm.[2] Although sharks within the family Somniosidae have generally been accepted to be non-luminous, Zameus squamulosus has photophores on its ventral epidermis.[3]
Reproduction
[edit]Its reproduction is ovoviviparous.[4]
Conservation
[edit]In June 2018 the New Zealand Department of Conservation classified the velvet dogfish as "Data Deficient" with the qualifier "Uncertain whether Secure Overseas" under the New Zealand Threat Classification System.[5]
