Surrounded by ocean on all sides, Taiwan has rich ocean resources. Because of their striking colors and forms, sea slugs are known as “undersea jewels” and they often attract the attention of divers. To introduce the beauty of marine life, Chunghwa Post is releasing a set of four stamps entitled “Marine Life Postage Stamps — Sea Slugs”. The designs follow:
1. Mexichromis multituberculata (NT$5): It has an ovate creamy white body, with purple-tipped tubercules on the back and purple, or sometimes orange-yellow, spots on the mantle edge. It can be found in the coral reefs off the northeast coast of Taiwan and Penghu.
2. Chromodoris willani (NT$5): It has an elongate-ovate bluish-gray body with black spots or longitudinal stripes. Its soft bluish-gray to white mantle has no obvious tubercules and its width is larger than the body. It can be found in the coral reefs off Kenting, Green Island and Orchid Island.
3. Gymnodoris ceylonica (NT$12): It has a cylindrical body, pointed at its posterior end; body is translucent white with small orange-red spots. Its mantle skirt is narrow and secondary gills are white with orange lines. The sea slugs shown in the stamp are mating. They exchange sperms with their genitalia and female ducts both located on the right side of their bodies. After mating, they separate to lay the fertilized eggs. They can be found in the coral reefs off Kenting and Green Island.
4. Glossodoris averni (NT$25): It has an elongate-ovate white opaque body. Its mantle is smooth and wide, with orange frilly edge. Its foot also has orange edges. It can be found in the coral reefs off Kenting.

A stamp folio, comprising a set of the four stamps and a set of pre-cancelled maximum cards, will be released along with the stamps.
