Dorsal cape: muted blue or bluish-gray. Eye to anus flipper stripes: darker blue or bluish-black. Dark stripe subtending the eye-to-anus stripe usually present. Some individuals have distinct subtending stripe from the eye-to-anus stripe at its origin near the eye, while others the two fuse farther behind the eye only to bifurcate further posteriorly.
