  River shark - Wikipedia, the free encyclopedia
The river sharks are members of the family Carcharhinidae, and thus share the basic characteristics of the group.
It is also known from the Alligator River system of the Northern Territory, where it occurs with Glyphis species C. Intriguingly, Glyphis specimens from the Adelaide River, Northern Territory, that have provisionally been identified as this species display very different vertebral counts (148 total vertebrae, versus 217 in specimens from the Bizant River).
These may be the same species as Glyphis species B. The species is presently in the process of being described by Sarah Fowler and Leonard J.V. Compagno.
