Biology

provided by Fishbase
Offshore on insular shelves of the Central Indian Ocean, distribution probably restricted (Ref. 114953). Maximum size is actually unknown, presumably a small- to moderate-size species given that the half-meter holotype is sexually mature (Ref. 55722). Biology is unknown, more specimens needed (Ref. 114953).
