Sequencing and characterization of the complete mitochondrial genome of the endangered Devils hole pupfish Cyprinodon diabolis (Cyprinodontiformes: Cyprinodontidae)

Abstract

The Devils Hole pupfish (Cyprinodon diabolis) is an imperiled cypinodontid fish endemic to Devils Hole, a single groundwater-fed pool in western North America characterized by temperature and oxygen conditions lethal to most fishes. In this study, we obtained the 16,499 base pair (bp) mitochondrial DNA sequence of C. diabolis. The mitogenome encodes 13 polypeptides, 22 tRNAs, 12S and 18S rRNAs, and an 832 bp D-loop region, and has a nucleotide composition of A, 25.69%; T, 27.32%; G, 17.49%; and C, 29.50% (GC content: 46.99%). The availability of this mitogenome will facilitate evaluations of C. diabolis genetic structure for management and conservation of this iconic endangered species.
