Description
The Butterfly Blenny (*Blennius ocellaris*) is a fascinating marine fish known for its distinctive ocellus (eye-spot) on its dorsal fin, resembling a butterfly wing. It is a bottom-dwelling species that prefers rocky crevices and sandy substrates, often seen perching and observing its surroundings. While generally peaceful, it can be territorial towards conspecifics or similar bottom-dwellers.
