The napoleon wrasse is a large, colorful fish found in coral reefs across the tropical waters of the Indo-Pacific region. Known for its distinctive hump on the forehead and vibrant blue and green patterns, it can grow up to 2.3 meters (7.5 feet) in length. This species plays a crucial role in maintaining the health of coral ecosystems by feeding on sea urchins and other invertebrates. Napoleon wrasses are social creatures, often seen swimming alone or in small groups. They are known for their intelligence and can recognize individual humans. Unfortunately, they are classified as vulnerable due to overfishing and habitat loss, making conservation efforts essential for their survival.
