Profundulus parentiae

  Citing the authors, this species "is named in honor of Dr. Lynne Parenti, who has made many important contributions to our knowledge of the systematics, biogeography, biology, and morphology of cyprinodontiforms as well as numerous other groups of fishes." Lynne Rosemary Parenti is an honored Research Scientist and Curator of Fishes at the National Museum of Natural History of the Smithsonian Institution. The species name can be translated with "Parenti's Profundulus".

  The genus Profundulus was erected by Carl Leavitt Hubbs in 1924 after recognizing differences to Fundulus in "several important respects". For him, "as the more generalized members of Fundulus, Cynolebias and some other american genera of the Cyprinodontidae, as well as the less specialized Goodeidae, resemble the species of Profundulus in habitus, it seems not improbable that Profundulus, of all american genera, diverges least from a general ancestral cyprinodont type." The ancient Greek word "pro" (πρό) means "before", so the name of the genus refers to this fact, that Hubbs believed that the members of Profundulus are basal to Fundulus. The genus Fundulus again can be derived from the Latin word "fundus" which means bottom; the suffix "-ulus" is also of Latin origin and indicates a diminutive. The genus Profundulus can therefore be translated with "before or older than the little one from the bottom". This odd name is in connection with the English expression "mud minnow" for Fundulus heteroclitus, with the name originating from its method of avoiding freezing during the winter months. When winter arrives, they burrow their way into the sediment and mud at the bottom of their habitat.
