66. There are a Iot of underwater wonders in the world. Did you know that...!
• One type of deep-sea squid is born with both eyes the same size. As it gets older, though, its right eye grows up to four times bigger than its left eye.
Some scientists think the squid uses its large eye to see in deep water and the smaller eye to see in shallow water.
Other scientists think the opposite may be true.
• Dugongs, or sea cows, may have started the mermaid legend. The largest dugongs were Steller’s sea cows.
They were discovered in 1741 but sailors ate so many that the sea cows became extinct 27 years later.
• Blue whales have the biggest babies of any animal. A new-born whale can weigh over 5 tonnes, some 1,000 times heavier than a new-born human baby.
It drinks 600 litres of its mother’s milk a day and by the age of seven months weighs 23 tonnes. In this time its mother loses 30 tonnes.
• Pure white beluga whales live in the Arctic Ocean. New-born belugas are reddish brown. They turn gray and finally white when they are five years old. Belugas are nicknamed “sea canaries” because they often make loud chirping noises.
• Sperm whales can hold their breath for almost two hours when they dive for food.
One whale was found with two deep sea sharks in its stomach. It must have dived 3,000 m down to catch them.
