Capture depth unknown, but probably from deep slopes of the Sulu Sea and adjacent waterways. the largest paratype (SUML MMLM 018) was measured in 1999 at 896 mm TL (Compagno et al., 2005) and shrank to 878 mm TL when measured a decade later. Of the two known males, one was sexually mature (621 mm TL) and the slightly larger holotype was at a late adolescent stage (657 mm TL); birth size unknown (Ref. 94808)..
