[2] This species of nudibranch is found in the central area of the Indo-Pacific region from Malaysia, Indonesia and the Philippines to the Marshall Islands.
The mantle edge and the foot are bordered with white and orange to yellow lines in which the width and the color intensity can vary greatly from a specimen to another.
These stored chemicals are unpleasant to some surrounding fish, allowing Chromodoris annae to avoid predation.
[6] Along with toxin production, it is also believed that the vibrant coloration of Chromodoris annae could be considered aposematic and may be a visual deterrent for predators.
[5] Chromodoris annae is a planar spawning species, meaning that this nudibranch lays a flat, two-dimensional, egg mass.
[16] Chromodoris annae lays egg masses in an arrangement that begins in the center and works its way outward, creating a spiral formation.
