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.

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).
栖息于长满植物的小溪,泥坑与路傍沟渠。
