Etymology: Dicologlossa: Greek, di = two + Greek, kolo = cut + Greek, glossa = tongue (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; depth range 10 - 460 m (Ref. 5304), usually 10 - 150 m (Ref. 31498). Subtropical; 47°N - 35°S, 19°W - 36°E
Eastern Atlantic: Bay of Biscay and the Mediterranean to the Cape of Good Hope, South Africa.
Length at first maturity / Size / Weight / Age
Maturity: Lm 17.1, range 17 - 19.9 cm

Estimates based on models
Preferred temperature (Ref. 115969
): 12.5 - 27.6, mean 18.2 °C (based on 576 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00640 - 0.00859), b=3.03 (2.99 - 3.07), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.49 se; based on food items.
Generation time: 3.9 (2.6 - 8.7) years. Estimated as median ln(3)/K based on 10 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (K=0.38-0.47).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (31 of 100) .
