Discodoris schmeltzianaBergh, 1877
This weeks BOW is a beautiful Discodoris from the Philippines and Japan. It was recently introduced in Atsushi Onoís new book Opisthobranchs of Ryukyu Islands on page 136 as his Discodoris sp. 2. Onoís photo may be the first presentation of this colorful dorid nudibranch in a popular publication. Mikeís make two.
Donít know much about the species but it is relatively common in the Philippine Archipelago. It is recognized by the ridge like hump down the center of the dorsum and the aggregation of tubercles on the notal surface, the center few of which are lavender or violet in color. Individuals may vary in background coloration from that seen above to lighter individuals, but the aggregation of lavender tubercles surrounded by yellow ones certainly gives it away.
Lets keep our eyes open for this beauty so we can extend its geographic range and learn more about its biology.
