A beautiful orange nudibranch with black spots with white ring around them.

• Nudibranchs are often casually called "sea slugs", a non-scientific term which has led some people to assume that every sea slug is a nudibranch
• Nudibranchs occur worldwide
• Nudibranchs live at virtually all depths of salt water, but reach their greatest size and variation in warm, shallow water.
• They vary in adult size from 20 to 600 mm.
• Nudibranchs are hermaphroditic, and thus have a set of reproductive organs for both genders, but they can rarely fertilize themselves.
