座頭鯨 (ざとうくじら, zātō kujira), or the humpback whale, is a large marine mammal known for its distinctive body shape and long pectoral fins. These whales can grow up to 16 meters (52 feet) in length and are recognized for their acrobatic behaviors, such as breaching and slapping the water with their fins. They are found in oceans worldwide and migrate long distances between feeding and breeding grounds. 座頭鯨 primarily feed on small fish and krill, using a technique called bubble net feeding to trap their prey. They are known for their complex songs, which can last for hours and are believed to play a role in communication and mating. Conservation efforts are in place to protect these magnificent creatures from threats like hunting and habitat loss.
