The complete mitochondrial genome of the deep-sea paskentanid snail Alviniconcha marisindica (Caenogastropoda: abyssochrysoidea) from the Carlsberg Ridge

Abstract

AbstractAlviniconcha marisindica Okutani 2014 is a deep-sea gastropod inhabited in hydrothermal vents of the Indo-Pacific. It belongs to superfamily Abyssochrysoidea. In the present study, we report the complete mitochondrial genome of A. marisindica, which is 15,979 bp in length and contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes. The nucleotide composition is 29.19% of A, 38.22% of T, 16.88% of G, and 15.71% of C. The phylogenetic analysis indicates that A. marisindica and A. boucheti clustered in the Abyssochrysoidea clade with high bootstrap support. The mitochondrial genome of A. marisindica provides valuable molecular data for further research on the evolution of deep-sea gastropods.
