혹등고래, 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 in length and weigh around 40 tons. They are found in oceans worldwide and are famous for their acrobatic behaviors, such as breaching and slapping the water with their fins. Humpback whales are known for their complex songs, which can last for hours and are believed to play a role in communication and mating. They primarily feed on small fish and krill, using a technique called bubble net feeding to trap their prey.
