• Marine scientists can now take a whale's pulse..it's seven to nine beats a minute.
• The killer whale is a dolphin, technically. The pulse of a killer whale depends on where the whale is... at the water's surface, it's 60 beats a minute. Underwater, 30 beats a minute.
• The heart of one blue whale, caught in 1947, was actually put on the scales. It weighed 1,540 pounds.
• Normal body temperature of a whale is about the same as yours and mine.
• Arteries of a blue whale are so big a leopard could crawl through them.
• Even the biggest whales can jump all the way out of the water...with ease.
• It takes a blue whale three to five seconds to exhale a spout 30 feet high.
• You can't save a beached whale by pushing it back into deep water. Its displaced organs won't work anymore. So say the experts.
