Elassomatidae (Pygmy sunfishes)
Etymology: Elassoma: Greek, elasson = smaller + Greek, soma = body (Ref. 45335).
Eponymy: James Erwin Böhlke (1930–1982) and his wife Eugenia Louisa Böhlke née Brandt (1929–2001) were both ichthyologists who worked at the Academy of Natural Sciences of Philadelphia, where he was Curator of Ichthyology (1954–1982). [...] (Ref. 128868), visit book page.

Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 4; Radios blandos dorsales (total) : 8 - 12; Espinas anales: 3; Radios blandos anales: 5 - 8. Mouth is terminal and upturned. Normally has 12-14 vertical bars along the body, alternating with iridescent interbars of approximately equal width. Sympatric species have head scales or humeral spots and ocular bars.
Body shape (shape guide): fusiform / normal; Cross section: oval.
Are generally cryptic or solitary (Ref. 58006). Inhabit heavily vegetated creeks, sloughs and roadside ditches. Feed on microcrustaceans and other small, benthic invertebrates (Ref. 58006). Oviparous, eggs are found in vegetation or just on the substrate (Ref. 58006).
Eggs are guarded by the male (Ref. 58006).
