Etymology: Rhombosolea: Greek, rhombos = paralelogram + Latin, solea = sandal (Ref. 45335). More on author: Günther.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; depth range 0 - 100 m (Ref. 33839). Subtropical
Eastern Indian Ocean and Southwest Pacific: south coast of Australia; New Zealand (Ref. 5755).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 45.0 cm TL male/unsexed; (Ref. 9563)
soft rays: 40 - 50. Body deep (47-60% SL). Snout slightly extended into fleshy process projecting more or less in front of oblique mouth. Scales very small, rather firmly attached; cycloid on both sides, covering head except well anteriorly. Caudal fin rays 14 -17 (Ref. 33839).
Common on silty sand substrates from estuaries and inshore waters down to 100 m depth. Juveniles occasionally entering rivers.

Estimates based on models
Preferred temperature (Ref. 115969
): 11.9 - 18.3, mean 16.6 °C (based on 248 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01778 (0.00772 - 0.04098), b=2.97 (2.76 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.3 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.).
Vulnerability (Ref. 59153
): Moderate vulnerability (40 of 100) .
