Etymology: Ecsenius: Greek, exenios, -os, -on = uncontrolled, immoderate.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 20 m (Ref. 86942). Tropical
Western Pacific: known only from the Great Barrier Reef. More recently reported from the Chesterfield Islands (Ref. 11897).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.8 cm TL male/unsexed; (Ref. 2334)
(total): 12 - 13;
soft rays: 15 - 17;
Vertebrae: 31 - 33. Dorsal fin XII or XIII (rarely XIII), 13-15, deeply incised between spinous and segmented-ray areas. Anal fin II,15-17. Pectoral fin 12-14 (rarely 12 or 14). Segmented caudal-fin rays 13. Vertebrae 10 + 21-23. Dentary incisor teeth which includes anterior canines very similar in appearance from incisors, 46-54 in males and 48 to 56 in females, averaging more in females than males; posterior canines 0 or 1 (usually 1). Lateral line without vertical pairs of pores, extending posteriorly to point between vertical from interspace between 9th and 10th spines and vertical from base of 11th dorsal-fin spine (rarely anterior to base of 10th spine). With cirrus on posterior rim of anterior nostril; absent on anterior rim. Posterior portion of body with sparse peppering of fine, dark spots (Ref. 5296).
Adults feed mainly on a diet of coral polyps and mucous (Ref. 94105). 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).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00332 - 0.01655), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
