The masked blenny is a small marine fish belonging to the family Blenniidae. It is commonly found in shallow waters of the Caribbean Sea and Atlantic Ocean. This fish is known for its distinctive appearance, featuring a prominent, mask-like pattern on its face, which helps it blend into its surroundings. Masked blennies typically inhabit rocky reefs and coral environments, where they can find shelter in crevices. They are primarily herbivorous, feeding on algae and plant matter. Their unique behavior includes darting in and out of hiding spots, making them an interesting species to observe in their natural habitat.
