Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Opistognathidae (Jawfishes)
Etymology: Opistognathus: Greek, opisthe = behind + Greek, gnathos = jaw (Ref. 45335);  albicaudatus: From the Latin albus (white) and cauda (tail). The suggested common name is whitetail jawfish (Ref. 88069).

Environment / Climate / Range Ecology

Marine; demersal; depth range 25 - 30 m (Ref. 88069).   Tropical; 12°N - 11°N, 93°E - 94°E

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Opistognathus albicaudatus is only known from Fusilier Strait in the Andaman Islands and appears to have an allopatric distribution with respect to its presumed closest relative O. variabilis.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 9.5 cm SL male/unsexed; (Ref. 88069)

Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 15; Anal spines: 3; Anal soft rays: 15. A species of Opistognathus with an elongate supramaxilla and maxilla whose posterior end is produced as a thin flexible lamina that in adults extends to or beyond rear margin of opercle; inner lining of upper jaw and adjacent membranes with one conspicuous black stripe; in life, caudal fin uniformly white; first gill arch with conspicuous, small dark blotches (8–11), each adjacent to a gill-raker base; dorsal fin XI, 15; body with about 72–75 oblique scale rows (Ref. 88069).

Biology     Glossary (e.g. epibenthic)

Habitat consisted of a flat, current-swept (3+ knots) sand and rubble plain at approximately 25–30 m depth without coral growth but with an occasional low, stunted gorgonian sea fan present. Opistognathus cyanospilotus, previously known from the Andaman Sea and Bali but not from the Andaman Islands, occurs in the same environment as O. albicaudatus and was collected from four separate burrows (Ref. 88069).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [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 body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
