The Short-tail Catshark (Parmaturus bigus) is a deepwater catshark known only from a single specimen collected from near the Saumarez Plateau, northeast Australia, at 590–606 m depth. The only known specimen, an adult female, measured 71 cm total length. This species may be a rare endemic with a restricted range. Further specimens and research are required, and at this time, there is insufficient information available to assess the species beyond Data Deficient.
