Scientific name: Nudibranchia
Nudibranchs, often referred to as sea slugs, are a diverse group of colorful and striking gastropods known for their intricate shapes and patterns. They lack a protective shell, which is unusual for gastropods. Nudibranchs are popular in the reefkeeping hobby for their aesthetic appeal and their role in controlling certain pests, such as aiptasia. They exhibit a variety of feeding habits, from sponges to hydroids, and some even display kleptoplasty, where they incorporate photosynthetic material from their prey into their own tissues. Care should be taken when introducing them to an aquarium, as they have specific dietary needs and may not thrive without their preferred food sources.
