Complete mitochondrial genome of the Starhead Topminnow (Cyprinodontiformes: Fundulidae).

Topminnows of the Teleost genus serve as model organisms in ecotoxicology because of their broad physiological tolerance and propensity to breed in captivity. This research has been primarily limited to intraspecific comparisons, due to incomplete understanding of the evolutionary history of the genus, which is necessary for use of phylogenetic comparative methods. Interspecific relationships of topminnows remain unresolved, despite recent advances in mitochondrial and nuclear genome sequencing.
