Etymology: Ecsenius: Greek, exenios, -os, -on = uncontrolled, immoderate.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 6 - 10 m (Ref. 5296). Tropical
Western Pacific: New Caledonia and New Hebrides (Vanuatu).
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 4.5 cm SL male/unsexed; (Ref. 5296)
Dorsal spines (total): 12; Dorsal soft rays (total): 14 - 15; Anal spines: 2; Anal soft rays: 16 - 17; Vertebrae: 33. Dorsal fin XII.14 or 15, with deep notch between spinous and segmented-ray portions. Anal fin II,16 or 17. Pectoral fin 13. Segmented caudal-fin rays 13. Vertebrae 10 + 23. Dentary incisor teeth 50-54 which includes anterior canine teeth very similar in appearance with incisors; posterior canines 1 on each side. Lateral line without vertical pairs of pores, terminating posteriorly at some point between vertical from interspace between dorsal-fin spines 10 and 11and vertical from first segmented ray. With cirrus on posterior rim of anterior nostril; absent on anterior rim. Dark spots on posterior half of body tile-like, surrounded and separated from each other only by pale, grout-like (interconnected) network (Ref. 5296).
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).

Estimates based on models
Preferred temperature (Ref.
123201): 25.1 - 29.5, mean 28 °C (based on 424 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00356 - 0.01695), 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.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
