Feeds mainly on small benthic organisms near the bottom (e.g., small shrimps, crabs, and isopods) (Ref. 129348). Smith-Vaniz, W.F,, L. Tornabene and R.M.

Colouration: sides with two rows of pale spots, each approximately diameter of eye; body with six vertically irregular, evenly spaced bands, widest on mid-side, and two rows of six pale spots, each spot approximately diameter of eye; buccal area surrounding esophageal opening is pale. Also easily disinguished from its congeners by the divergence in the mitochondrial gene COI, as specimens form a monophyletic group that differs from its closest relative (O. whitehursti) by an average of 11% (654 bp analyzed) (Ref. 129348).
