Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 2.5 cm TL maschio/sesso non determinato; (Ref. 7251)

Distinguished by the following characteristics: first dorsal fin spines VII; completely united pelvic fins; scales only on posterior section of the trunk; four modified basicaudal scales at the base of the caudal fin; light to dark brown body color with faint internal bars visible on lighter specimens; 2-4 enlarged re-curved canines in each jaw that project out of the mouth, point out and up in the upper jaw, down and back on the lower jaw (Ref. 92840).
Found in association with large barrel sponges, generally along outside hiding in crevices, also sometimes within the sponge tubules (Ref. 92840).

Estimates based on models
Preferred temperature (Ref.
123201): 24.4 - 28.2, mean 27.3 °C (based on 599 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
