There is little information available on Whitefin Smoothhound (Mustelus widodoi) other than the collection of 44 individuals from market surveys of Indonesia. Possibly has a very restricted range but it is poorly defined currently. This species is thus assessed as Data Deficient, but the low numbers caught could possibly be a reflection of past decline in this species. Further information is required on this species in the future.
