It’s a fairly close contest between the sperm whale and the blue whale. For most whale and dolphin species, the length of their intestines works out as: (body length0.762) x 17.02. That comes to more than 150m of intestine in the case of a large sperm whale and possibly as much as 220m for a blue whale. While this sounds enormous, it’s actually only seven or eight times the whale’s body length. In contrast, a cow has intestines that are 20 times as long as its body – that’s 40m for a 2m-long cow!
