Abstract

Comaster schlegelii, belonging to the family Comatulidae, is a variable feather star distributed in the Pacific Ocean. The complete mitochondrial genome of this species was 15,887 bp in length, consisting of 13 protein-coding genes, 22 transport RNA genes, two ribosomal RNA genes and one control region. The whole mitochondrial genome of C. schlegelii had a high AT content of 72.73%. The phylogenetic relationship was reconstructed with 16 relevant echinoderms, which revealed C. schlegelii was closely clustered with Anneissia pinguis in the family Comatulidae.

Keywords: Comaster schlegelii; Comatulidae; Crinoidea; Mitochondrial genome.
