The complete mitochondrial genome of cf. (Polychaeta, Cirratulidae) from Dok-Do, Korea.

Mitogenome sequence of cf. (Terebellida, Cirratulidae), a species of marine polychaete worm, was determined in this study. This is the first mitogenome reported for genus and family Cirratulidae. This complete mitogenome is 15,495 bp in length, containing 13 protein coding genes (PCGs), two ribosomal RNAs (rRNAs), and 23 transfer RNAs (tRNAs). The mitogenome of cf. has high A + T content of 59.5% (A, 29.5%; C, 26.9%; G, 13.6%; T, 30.0%). In neighbour-joining (NJ) analysis, cf. is clustered with the components of order Terebellida.
