The calf swims no

more than a foot

(30 centimetres) away

from its mother’s side

where there is calmer

water and the wake

from its mother helps

to pull it along.

Dolphins have also learned a cool trick

– bow-riding. When a ship pushes
forward through the water, it creates
a pressure wave at its bow. Dolphins

love to chase a ship and surf the pressure
wave. Speed, danger, fun? I like the way
those dolphins think!
