Molecular phylogeny of the livebearing Goodeidae (Cyprinodontiformes)

Molecular Phylogenetics and Evolution, 2004
The Goodeinae is a speciose group of viviparous freshwater fishes endemic to the Mesa Central of Mexico. The current taxonomy of the group is based on morphology associated with viviparity and several of the groupings are questionable. We sequenced part of the mitochondrial cytochrome c oxidase subunit I (COI) gene (627bp) and control region ...

The trophotaeniae of the goodeidae, a family of viviparous cyprinodont fishes

Journal of Morphology, 1937
AbstractThe embryos of twenty‐one species of the family Goodeidae have extensive rectal processes (trophotaeniae) which serve as absorptive organs, by means of which the embryos while they are retained in the ovarian cavity absorb substances dissolved in the ovarian fluid. Embryos of three species have not been available for study. No trophotaeniae are

A New Key Character in Males of the Family Goodeidae (Cyprinodontiformes) [PDF]

open access: yesNature, 1965
IN the family Goodeidae, unlike the other viviparous Cyprinodontiformes, the male anal fin is not modified into a gonopodium. Three years ago, we discovered in Skiffia lermae (Goodeidae) a muscular structure which seems to serve as a reproductive organ and which we called a “pseudo-penis”1,2.
