Dolphins and porpoises, members of the Cetacea order, often confuse people due to their similarities. However, subtle differences set them apart. Dolphins, the larger species, have a more elongated and streamlined body with a clearly visible beak. They are renowned for their playful and acrobatic nature. Porpoises, on the other hand, are smaller and chubbier, with a shorter, rounded beak. They typically display a more reserved behavior compared to their dolphin counterparts.
