Kurzbeschreibung Morphologie | Morphometrie

Snout long, narrow, sharply pointed. Dorsal scute row striating from just behind the head and extending to about behind a vertical through the anus, with more than 20 scute. Ventral scute row not reaching anus. Scute keels generally smooth blade-like, without multicuspid tips in small individuals (<30 cm), becoming more multicuspid with size. Scales adherent; belly completely scaled.
