The Indonesian houndshark (Hemitriakis indroyonoi) is a species of houndshark in the genus Hemitriakis. It is a part of the family Triakidae. The shark was named for Dr. Indroyono Soesilo, a researcher who supports the conservation of shark and ray fisheries in Indonesia. It was described by William T. White, Leonard J.V. Compagno, and Dharmadi in 2009.
This is an endangered small shark that lives in Indian Ocean waters, mainly endemic to Indonesia. Their survival is threatened by the local fishing practices, such as longline fishing, done by fisherman on the coastlines of Indonesia and the surrounding islands. They live at depths between 50-100 meters on the ocean floor making them vulnerable to overfishing done with trawling like techniques.
