A small to near pupil-sized (Ref. 48635) basicaudal spot is centered at the level of the lateral stripe (Ref. 37816). Its lower edge at level with the lower ray of the central two rays in the caudal fin. The spot is usually absent in deep water or at night and often fades in the afternoon (Ref. 48635).
