👉 Tupeinae are a group of small, elongated, bipedal terrestrial animals that belong to the family Cetacea, commonly known as whales. They are characterized by their elongated body shape, which allows them to swim and dive efficiently in water. Tupeinae include baleen whales, such as the blue whale (Balaenoptera musculus), and sperm whales, such as the sperm whale (Delphinapterus catus).
