Size


The baleen whales are larger than the toothed whales. Female baleen whales are slightly larger than the males.

The biggest whale is the female blue whale, which grows to be about 94 feet (29 m) long - the height of a 9-story building. There are undocumented sighting of blue whales up to 110 feet (34 m) long. These enormous animals need to eat about 4 tons of tiny krill each day, obtained by filter feeding miniscule animals and plants through sieve-like baleen. Adult blue whales have no predators except man. The blue whale is the largest animal that ever lived on Earth; it is even bigger than any of the dinosaurs were. The largest dinosaurs were Jurassic period sauropods, long-necked, long-tailed plant-eaters that were about 100 feet long but weighed much less than the blue whale.

The smallest whale is the dwarf sperm whale which as an adult is only 8.5 feet (2.6 m) long.
