The complete mitogenome of the Critically Endangered smalltooth sand tiger shark, (Lamniformes: Odontaspididae).

Here, we report the first complete mitochondrial genome for the smalltooth sand tiger shark, (Risso, 1810). The circular mitochondrial genome was found to be 16,682 bp in length and contains 37 genes, a control region and the replication origin of the L-strand (O). The base composition of this mitogenome is 32.6% A, 23.3% C, 12.8% G, and 31.3% T. Phylogenetic analysis of Lamniformes indicates that did not group with and so the taxonomic classification of Odontaspididae needs to be revised. This study promotes conservation genetics for this poorly studied shark species which is listed critically endangered in the Mediterranean Sea.
