The smallbelly catshark (Apristurus indicus) is a catshark of the family Scyliorhinidae found in the western Indian Ocean near Somalia, the Gulf of Aden, and Oman, at depths between 1,300 and 1,840 m. Its length is up to 34 cm, although this measurement is of an immature specimen. The smallbelly catshark is not well known. It is found on continental slopes, and is probably caught by bottom trawlers. The reproduction of the smallbelly catshark is oviparous.
