The characters in "My First Dive with the Dolphins" were Reed, Ernestine, Lucky, and Arnie. That's all I can think of. :)
they swim
Because if they dive into the water at a straight angle while moving, they could injure themselves.
Maybe, because they both can dive !
dolphins dive deep into the dark damp water
by using their great body strength and lung capacity
first of all how do you get dive in the first place?
They don't breathe under water, certainly not like fish do. When they dive they hold their breath, just like whales and dolphins do when they dive. They close their nostrils as they dive to prevent water from coming into their lungs, just as whales/dolphins close their blow-holes before they dive or submerge themselves in the water.
dolphins can breathe underwater for about 15 minutes after that they have to go back to the surface to breathe some oxygen ps: dolphins are mammals
Bottle nose dolphins can swim in shallow water because they can inhale the air humans inhale to. The dolphins can all so dive to under 1000fl to the bottom of the sea
"Dive in head first" is to rush into a situation without thinking.
The deepest dolphin dive ever recorded was a bottlenose dolphin called tuffy. He dove 300 meters (990 ft.) however, dolphins do not dive very deep at all. They usually live in shallow waters.
The bottle-nosed dolphin normally dives to depths of 150 feet [45 m], but the deepest recorded dive for a dolphin is 1,795 feet [547 m]! How does this mammal survive such a dive? Its heartbeat slows down during the dive, and blood is diverted to the heart, lungs, and brain. Also, its muscles contain a chemical that stores oxygen.
