Krefftii

Krefftii is a scientific epithet that may refer to several different species, most notably a type of freshwater fish and a species of frog. The most common association is with the South American lungfish, Lepidosiren paradoxa, which is sometimes referred to by the trinomial name Lepidosiren paradoxa krefftii. This species is found in the freshwater systems of South America, inhabiting slow-moving, oxygen-poor waters where it can breathe atmospheric air. It is a long, eel-like fish with a dark, mottled coloration.

Another notable organism bearing the specific epithet krefftii is Adelophryne krefftii, a species of frog. This amphibian is native to the Atlantic Forest of Brazil. It belongs to the family Eleutherodactylidae and is characterized by its small size and terrestrial habits. The common name for Adelophryne krefftii is often the Krefft's frog or Krefft's tiny frog.

The epithet krefftii is derived from the surname Krefft. It is typically used in biological nomenclature to honor a person, likely a naturalist or collector. The exact individual honored by the name krefftii in both the fish and frog species may vary or be attributed to a single influential figure in natural history. Further research into the etymology of each specific scientific name is required for precise attribution.
