Morphology | Morphometrics
A relatively small (max. size 474 mm TL) Atelomycterus with the following combination of characters: relatively short preoral length, 4.0-4.6% T; short interdorsal space, 11.6-12.9% TL; high pectoral-pelvic to pelvic-anal ratio 1.28-1.48; dorsal fins weakly falcate, with posterior margins vertical or sloping anteroventrally from fin apices; prebranchial denticles strongly tricuspid with narrow, elongate medial cusps; claspers of adults short, not stubby, not tapering sharply distally, outer length 8.3-9% TL, base width 5.4-6.3% of outer length; clasper glans covering more than half of clasper; cover rhipidion relatively narrow; rhipidion large, relatively low, and only partly concealed by cover rhipidion and exorhipidion; exorhipidion small with proximal end well behind distal end of cover rhipidion; total vertebral centra 154-163, precaudal centra 101-106; dorsal surface with well-defined dark saddles consisting mainly of four, partly coalesced, diffuse-edged, dark brown blotches; white partly coalesced, diffuse-edged, dark brown blotches; white spots absent from body and rarely on fins; inner margin of pale tips of dorsal fins orientated almost vertically; upper pectoral fin lacking a broad, sharply defined whitish margin.
Biology unknown; presumably reef-dwelling, inhabiting holes and crevices on reefs, like other related catsharks. Presumably oviparous. Diet probably dominated by small invertebrates . Caught irregularly by fisheries operating over coral reefs. Utilized for its meat but of limited value (Ref.58048).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this BS (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Low fecundity (RF)).
Fishing Vulnerability (Ref. 59153
): Moderate vulnerability (37 of 100).
