Short description Morphology | Morphometrics

Dorsal soft rays (total): 54; Anal soft rays: 39; Vertebrae: 34. This small-sized sole (largest reported size at least 14.0 cm SL) have no external eyes visible on right side; body overall tear-drop shaped; head relatively long (head length 25.5 % SL) and, rounded, its width 127.6 % HL with deepest part of body (42.6 % SL; body depth at anus 36.8 % SL, located about at point about equal to 1/4 SL, the body gently tapering to caudal peduncle (with depth 6.2 % SL); pectoral fin on right side of body absent; all unpaired fins confluent; D 54; A 39; caudal-fin rays 12; pelvic-fin rays 3 on both left and right; no gill rakers on gill arches; 9 + 25 = 34 (Ref. 126196).

Occurs on soft muddy-slit substrate. Caught as bycatch of Macrobrachium rosenbergii fishery with the use of a method called 'Belat' (net length ca15 m, mesh about 4-5 cm wide) held in place by long wooden stakes laid around a shallow dip in the river bank during low tide, and left for one tidal cycle before retrieval (Ref. 126196).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00473 - 0.02021), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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