Etymology: Paralichthys: Greek, para = the side of + Greek, ichthys = fish + Greek, suffix, oides = similar to (Ref. 45335). More on author: Valenciennes.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; oceanodromous (Ref. 51243); depth range 1 - 45 m (Ref. 43588), usually 1 - 20 m (Ref. 43588). Subtropical; 0°C - ; 23°S - 41°S

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 62.4 cm TL male/unsexed; (Ref. 111977); common length : 32.0 cm SL male/unsexed; (Ref. 43588)
soft rays: 52 - 59;
Vertebrae: 35 - 36. Body shape oval, with the greatest breadth 2.5 times in length. Eyes are on the left side, close together, and equally in advance. Teeth are in a single series, sharply pointed. Dorsal fin origin aligned with eyes. Lateral line arched over the pectoral fin. Eye side of the body slightly rough, with finely ciliated scales (Ref. 3157).
Enters coastal lagoons (Ref. 36453). Feeds on pelagic and benthic species of crustaceans (penaeids and brachyurans), and of lesser importance, fishes (Ref. 43588).

Estimates based on models
Preferred temperature (Ref. 115969
): 13.4 - 22.8, mean 16.1 °C (based on 118 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00429 - 0.01168), b=3.12 (2.98 - 3.26), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.54 se; based on food items.
Generation time: 9.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
