Common name: Roboastra Nudibranchs

Roboastra is a genus of colorful nudibranchs, known for their striking patterns and predatory behavior. They are found in tropical and subtropical seas and are often observed hunting other smaller sea slugs. Roboastra species are not common in the aquarium trade due to their specialized diets and the difficulty in providing appropriate live prey. They exhibit fascinating behaviors and are a subject of interest for marine biologists studying chemical ecology and defense mechanisms.
