Anna's Magnificent Slug

Seen in Apo Island, near Dauin (Oct 2, 2012).
Chromodoris annae is a species of sea slug, a very colorful nudibranch, a shell-less marine gastropod mollusk in the family Chromodorididae. Chromodoris annae is blue with black longitudinal lines, and a white and orange mantle edge. The blue areas are flecked with tiny black dots. The colors can vary. This species is similar in appearance to Chromodoris elisabethina although lacks that species' central black line on the upper mantle.
