...
dolphins often leap clear of the water when travelling at speed. This is because the
density of water is much greater than that of air and they are able to travel faster by leaping out of the water.
...whale and dolphin mothers ‘suckle’ their young underwater! Mothers have muscular
mammary glands and ‘squirt’ their milk into the calf’s mouth, to ensure that the calf takes in as much of the energy rich
milk as possible.
...on average, a
whale or
dolphin will eat four to five percent of its body weight in food per day. That means that a 100 ton
blue whale will eat almost five tons of
krill per day, or that a 200kg
bottlenose dolphin will eat 10kg of fish per day!
...newborn cetacean calves ‘suckle’ three to four times each hour and will suckle from their mothers for six months or more.
