Dolphin By: Jada Marks

Dolphins typically swim at 3 to 7 miles per hour. They can go over 20 miles per hour when they work hard.
Dolphins generally eat fish, squid, octopus, and shrimp. Dolphins don't just open their mouths and eat fish; they use different hunting techniques to catch them. Bait ball: Dolphins often herd schools of fish into a bait ball before ploughing through it.
When this happened, the dolphin's ancestor had to slowly adapt to its new environment. Its front legs became flippers and its tail became flukes. Its back legs diminished till they were absorbed into the body. ... What dolphins have to keep them warm is a layer of blubber beneath their skin.

Although found mostly in warmer waters around the world, their habitat is diversified due to food accessibility and environmental factors. Scientists classify bottlenose dolphins as coastal or offshore ecotypes. Coastal dolphins thrive in warm shallow waters, and they are normally seen in harbors, bays and lagoons.

Dolphins survive by living within groups to protect one another, by eating various food found throughout the ocean and by breathing when they surface. Their bodies also help to support them after millions of years of evolution to the slender, torpedo shape that can swim quickly and powerfully.
Dolphins mate in much the same way as humans by expressing sexual attraction and desire, and when the time is right, the male enters the female to deposit his sperm. Unlike human mating, the actual dolphin mating process only lasts a few seconds.
Dolphins usually live up to 40 years. That is a really long time to live.
