|Scientific Name:||Hemitriakis complicofasciata Takahashi & Nakaya, 2004|
|Red List Category & Criteria:||Data Deficient ver 3.1|
|Reviewer(s):||Valenti, S.V. & Fowler, S.L. (Shark Red List Authority)|
The Ocellate Topeshark (Hemitriakis complicofasciata) is a recently described shark likely to be found in inshore waters at a depth of 90–100 m from Okinawa, Japan to Philippines, including the coast of Taiwan, Province of China. This species is believed to reach around 96 cm TL. Little else is known about this species biology. Ocellate Topeshark is possibly caught as bycatch in gillnet fisheries, but no information is available at this time. Due to the lack of data concerning this species’ biology and interaction with fisheries, it is assessed as Data Deficient, but should be reassessed as more information becomes available.
