Batrachus is a genus of fish commonly known as frogfish, which belong to the family Antennariidae. These unique fish are characterized by their unusual body shape and ability to camouflage themselves among coral and other underwater structures. They are found in warm, shallow waters, primarily in the Indo-Pacific region. Frogfish are known for their remarkable hunting technique, using a lure on their heads to attract prey. They can quickly open their mouths to create a vacuum, sucking in small fish and crustaceans. Their ability to change color and texture helps them blend into their surroundings, making them effective ambush predators.
