Abstract
In this study we describe the first complete mitochondrial sequence for the Critically Endangered Northern River shark Glyphis garricki. The complete mitochondrial sequence is 16,702 bp in length, contains 37 genes and one control region with the typical gene order and transcriptional direction of vertebrate mitogenomes. The overall base composition is 31.5% A, 26.3% C, 12.9% G and 29.3% T. The length of 22 tRNA genes ranged from 68 (tRNA-Ser2 and tRNA-Cys) to 75 (tRNA-Leu1) bp. The control region of G. garricki was 1067 bp in length with high A + T (67.9%) and poor G (12.6%) content. The mitogenomic characters (base composition, codon usage and gene length) of G. garricki were very similar to Glyphis glyphis.
