the white whale
I often comment that little Tommy is a big kid, and how he really likes to eat. Let's put that in perspective for a moment shall we?

    A Blue Whale's head is so wide that 50 humans would be able to stand on its tongue. Its heart is close to the size of a small car. A human baby could crawl through a Blue Whale's arteries. A newborn Blue Whale calf weighs more than an adult elephant. During the first 7 months of its life, a baby Blue Whale drinks approximately 400 litres (100 U.S. gallons) of milk every day. Baby Blue Whales also gain weight quickly: 90 kg (200 pounds) every 24 hours.
