Sulawesi is an island in Indonesia. It is situated off the city of Manado about 300 km (187 mi) east of Borneo. It is the world's eleventh-largest island. Sulawesi has 4 national parks (including Bunaken Marine National Park) and three marine protected areas. It is a favorite destination of divers.

Nudibranchs, commonly known as sea slugs, are colourful marine gastropod mollusks. Nudibranchs feed on sponges ananemones. They are hermaphroditic. As all other gastropods, nudibranchs are slow moving bottom dwellers. These beautiful sea slugs have fantastic and varied color patterns. They are usually brilliantly coloured. Most of them do no have a external protective shell.

Nudibranchs loose their shape and colors when they are taken away from their special micro-environments.

Risbecia tryoni are often found crawling in pairs with one attached to the back of the other. They belong to the family Chromodorididae
