The dolphin has been known as man’s best friend. Once a 28-year-old man who went swimming in the Red Sea with a group of dolphins, learnt the hard way just how caring these creatures can be. When the man was suddenly     1     by a shark, they saved him by forming a circle around him and     2     the shark away.

It’s not the first time humans are saved by dolphins and it’s been known for some time that dolphins will do for humans what they do for their own     3    . They are, in fact, the only animals in the world whose brains     4     ours in terms of size, and their     5     to feel emotion continues to attract scientists and doctors.

The only creatures that     6     dolphins, in fact, are sharks and man. We don’t necessarily harm them on     7    , but we catch them in fishing net s and we pollute the water they swim in.     8    , in fact, is one of the dolphins’ greatest problems. So with all the good they do for us, isn’t it time we started caring about them?
