(South Pacific flounders)
Etymology: Rhombosolea: Greek, rhombos = paralelogram + Latin, solea = sandal (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; demersal; catadromous (Ref. 51243). Subtropical; 34°S - 47°S
Southwest Pacific: endemic to New Zealand.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 25.0 cm TL male/unsexed; (Ref. 13730)
Inhabits shallow waters, generally at depth of less than 50 m. Juveniles gather in sheltered inshore waters, such as estuarine areas, shallow mudflats and sandflats, where they remain for up to two years (Ref. 9072). This species is poorly studied, fast growing and short lived (to at least 4 years) (Ref. 47621).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01820 (0.00804 - 0.04119), 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 ±0.2 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
): Low vulnerability (20 of 100) .
