Etymology: Ecsenius: Greek, exenios, -os, -on = uncontrolled, immoderate; dentex: Pre-Linnean source unclear; Latin, 'dens' = tooth or toothed, referring to the species' most prominent characteristic of having the highest average number of teeth within the Yaeyamaensis Group.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 0 - 4 m (Ref. 5296). Tropical
Western Indian Ocean: occurs only in the Gulf of Aqaba and northernmost part of the Red Sea adjacent to the gulf.

Morphology | Morphometrics
(total): 11 - 13;
soft rays: 15 - 17;
Vertebrae: 31 - 33. Dorsal fin XI-XIII.13-15 (rarely XI, XIII, or 15); incised between spinous and segmented-ray portions. Anal fin 11,15-17 (rarely 17). Pectoral fin 12-14 (usually 13). Segmented caudal-fin rays 13. Vertebrae 10 + 21-23. Dentary incisor teeth which includes anterior canines very similar in appearance with incisors, 49-59 in males and 53 to 63 in females, averaging more in females than males; posterior canines 0 or 1 (typically 1). Lateral line lacking vertical pairs of pores, extending posteriorly to point between verticals from 9th and 11th dorsal-fin spines, typically extending to or beyond 10th spine. With cirrus on posterior rim of anterior nostril; absent on anterior rim.
Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
