Abstract
Electric catfishes evolved the substantial electric organ that can instantly release powerful high-voltage electricity. To better study the phylogenetic position of the electric fish (Malapterurus electricus) in catfishes, in this study, we presented the complete mitochondrial genome of M. electricus assembled by the next-generation sequencing data. The mitogenome has 16,504 bp and contains 13 protein-coding genes (PCGs), 22 transfer RNA genes, two ribosomal RNA genes, an L-strand replication origin (OL), and a control region (D-loop). The overall base composition is A 31.08%, C 27.54%, G 14.81%, and T 26.57%. Phylogenetic analysis based on 13 PCGs of 43 species from Siluriformes showed M.electricus belonging to the Malapteruridae displayed a close relationship with Siluridae. Taken together, the complete mitochondrial genome of M. electricus would be beneficial for the study of the phylogenetic relationship of Siluriformes.
