 The Pondicherry has been spotted in rivers in India in the late 2010s.The first scientific description of the Pondicherry shark was authored by German biologists Johannes Müller and Jakob Henle in their 1839 "Systematische Beschreibung der Plagiostomen".Their account was based on a long immature male from Puducherry (formerly Pondicherry), India and three more paratypes from the same region.
