Howler monkeys are widely considered to be the loudest land animal. According to Guinness Book of World Records, their vocalizations can be heard clearly for 3 mi (4.8 km).

Other enormous land carnivores include the Polar and Kodiak bears. The African Bush elephant has earned the title of heaviest land creature, but it is an herbivore, and the giraffe, also an herbivore, is the tallest terrestrial animal. The largest ocean-dwelling carnivore is the sperm whale, which can grow to lengths of up to 80,000 feet.
