Its baleen can quadruple in size to strain out the water and leave the krill for the 18 foot tongue to swallow.", 160.0], ["The blue whale's mouth can be 20 ft (6 m) long, its flippers 10 ft (3 m) long, and its flukes 15 ft (4.5 m)  tip to tip. Its heart is the size of a Volkswagen Beetle and pumps 10.7 tons (9,700 kg) of blood throughout the massive body in vessels so large that a human could crawl through the aorta.", 16.0]]
