Etymology: Lepomis: Greek, lepis = scaled + Greek, poma = gill cover, operculum (Ref. 45335, 79012); cyanellus: cyanellus meaning blue (Ref. 10294). More on author: Rafinesque.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 7.0 - 7.5; dH range: 10 - 15. Subtropical; 18°C - 32°C (Ref. 12741); 50°N - 26°N
North America: Great Lakes, Hudson Bay and Mississippi River basins from New York in USA and from Ontario in Canada to Minnesota and south Dakota, USA, and south to the Gulf of Mexico; from Escambia River in Florida, and Mobile Bay in Georgia and Alabama to Rio Grande in Texas, USA.

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 31.0 cm TL male/unsexed; (Ref. 5723); common length : 20.0 cm TL male/unsexed; (Ref. 12193); max. published weight: 960.00 g (Ref. 4699); max. reported age: 9 years (Ref. 72492)
Adults inhabit quiet pools and backwaters of sluggish streams, lakes and ponds. Often near vegetation (Ref. 5723, 10294). Juveniles feed on immature insects and microcrustaceans (Ref. 10294). Nest spawners (Ref. 79012).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.01268 - 0.02075), b=3.11 (3.06 - 3.16), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.48 se; based on food items.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=5).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (31 of 100) .
