Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Serranidae (Sea basses: groupers and fairy basslets) > Anthiinae
Etymology: Pseudanthias: Greek, pseudes = false + Greek, anthias = a fish, Sparus aurata (Ref. 45335).

Environment / Climate / Range Ecology

Marine; reef-associated; depth range 20 - 100 m (Ref. 90102), usually 40 - 54 m (Ref. 9710).   Tropical

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 14.0 cm TL male/unsexed; (Ref. 8631)

Short description Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 16; Anal spines: 3; Anal soft rays: 7 - 8. Displays different or stronger color patterns when living together with similar looking species to enhance recognition by females which may lead to further speciation (Ref. 48635).

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

Indo-West Pacific: East Africa, Maldives and Indonesia.

Biology     Glossary (e.g. epibenthic)

Inhabits deep coastal drop-offs (Ref. 8631, 48635). In Java Sea, taken only in dead reef areas in somewhat turbid water (Ref. 8926). Closely related species such as P. pleurotaenia and P. bimaculatus may spawn at the same time and produce accidental hybrids (Ref. 48635).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00479 - 0.02884), b=3.03 (2.81 - 3.25), based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (20 of 100) .
