Were the "Dolphins" have HELPFUL nature?

I feel that a dolphin is a man's second best friend because a dolphin is just like us. A dolphin does not scream or shout when you come close to it. I have once ride on a dolphin ind it is a wounderful experience. Dolphins are a beautiful chatacter. They are like our shoulder that we need. I always like to ride on a dolphin's back. I would want to go and ride a dolphin again.

sure !they are real intelligent mammals! they might have sensed that something were wrong and came to their rescue! i would be on cloud nine if i had a dolphin they are just so cute! dolophins are sensitive mammals.the people that they saved must be really grateful!if i were to swim with dolphins i would be ever so lucky!it is very expensive just to pay for scuba diving imagine diving

I have seen documentaries on dolphins which shows sharks attacking humans and dolphins chasing the sharks away. It also show how dolphins save humans from drowning. Nowadays people are taking part in swim with dolphins programme to improve their health.Occassionally there are dolphins who become aggresive if they are provoked. My favourite animal is dolphin and I do not consider dolphin a fish as it is a mammal.
