Etymology: Asterorhombus: Greek, aster = star + Greek, rhombos = paralelogram (Ref. 45335); filifer: Name from Latin, 'filum' for filament and 'fero' for carry, referring to the long first dorsal-fin ray, as it appears in small specimens and when the membrane is furled around the ray.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 81 - 88; Anal soft rays: 63 - 69. This species is distinguished by the following combination of characters: palmate gill-rakers; uniserial dentition in both jaws; first dorsal-fin ray separated from remainder of fin, elongate, 0.8-1.7 in head length (HL), posterior membrane on ray broad, with a smooth margin, and running nearly entire length of ray; eyes usually with one tentacle, frequently branched; sexual dimorphism in interorbital width in specimens larger than ca. 60 mm SL, 8.9-18 in HL (1.6-3.1 % SL) in males, 15-21.2 (0.9-2.3 % SL) in females; body depth 2.0-2.5 in SL (40.4-50.1 SL); lateral line scales 56-67 (Ref. 57773).

Found near reefs, in gullies, or cave entrances on sand or coral- or rock-rubble bottoms at 3-57 m depth (Ref. 57759). Benthic (Ref. 58302). Feeds on small fishes and crustaceans (Ref. 89972).

Estimates based on models

Preferred temperature (Ref. 123201): 24.5 - 28.9, mean 27.4 °C (based on 378 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00912 (0.00408 - 0.02036), b=3.04 (2.85 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
