Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 7 - 8; Anal soft rays: 15 - 17; Vertebrae: 30 - 32. This species is distinguished from Malagodon madagascariensis by the following apomorphic features: lower anal-fin ray count 15-17 (vs. 18-19); longer caudal peduncle 26.8-39.8 (vs. 21.9-26.7% SL); expanded and platelike neural spine on arch of fifth vertebral centrum in both sexes (vs. thin and spinelike); neural spines on both sixth and seventh vertebral centra omewhat expanded and platelike dorsally (vs. narrow and spinelike) (Ref. 131565).
Body shape (shape guide): elongated; Cross section: compressed.

Biology     Glossary (e.g. epibenthic)

Inhabits a small, turbid swamp, with only a thin layer of clear water over a much more extensive highly sedimented layer, and all specimens were collected from this thin top layer of clear water (Ref. 131565).

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.7510 [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) 		3.1   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability
(Ref. 59153) 		Low vulnerability (10 of 100). 🛈
