Dolphins and Porpoises

Dolphins are born after a gestation period of 12 months.

That would depend entirely on the length of the mother. Calves are born the length of the mother's head. Sizes vary from 8 feet (under 1000 lbs or 453 kilograms) to 20 feet or more (3000 lbs or more or 1360 killograms or more!)

Dolphins were created in the beginning of the world. God created them. if you look in the bible God tells you the seven days of creation. Genesis 1:20 tells you "Let the water teem with living creatures, and let birds fly above the earth across the expanse of the sky."

No, you can't because the only place you can see a marine creature in an aquarium.

Dolphins can swim 1,000 feet down before taking a breath of air.

Scients believe that over a million years ago dolphins used to live on land because they can walk on their flukes in the water.But sharks didnt.

No. Dolphins can kill sharks by blocking their gills.

the appearance if a dolphin is a long sleek body, a snout like thing for a mouth (different lengths depend on the species) and a large flat tale.

First of all, the cheetah would probably run away. But if he stood and fought, the tiger would definitely win. Tigers are really dangerous, a lot more aggressive, and more sturdy. Cheetah's bodies are built more for speed than strength. They are both good in different ways, but the tiger is superior in strength.

Get together a group of people that feel strongly about what you do then think of ways to help, they can be saved!

an Atlantic spotted dolphin lives to about thirty in captivity, but i don't know how long it lives in the wild

dolphins. u just said it in the question, einstein

Believe or not, it tends to be done by airplane. They first capture it with a net then place the whale/dolphin in a sling-like contraption. It is taken to a huge truck and the people keep the animal wet. It then gets loaded into a plane to be shipped off to another Marine Park.

On average, dolphin babies are around 3.5 feet long when they're born. They weigh around 40 pounds at birth and quickly grow to be able to avoid predators like great white sharks.

A dolphin nostrils are actually located on it's back, and is called a blowhole. A dolphin swims to the surface, pushes it's back to the air, and breathes in. Now it has fresh air. Dolphins are evolved to be very efficient at using oxygen, so they do not have to get air very often.

Dolphins are mammals, which means they are warm-blooded. Warm-blooded creatures thrive better in warm water and this is what most dolphins prefer.

Adult Great Whites are apex predators. Apart from the Orca (Killer Whale), there are no known predators that may attack or kill a Great White. In regions where both the Orca and the Great whites inhabit and compete for food, Orcas may attack and kill these sharks. Since Orca's are much larger than them, they can attack and even kill great whites.

I think there are about 50 amazon river dolphins left and only a few Chinese river dolphins left. there are other kinds of river dolphins but I don't know how many are living. They are endangered.

Well really there are just the pink dolphins left. And they are endangered. There are only like 1200 left in the Amazon River. They are the last surviving river dolphin.

Between 5 and 10, depending on how big it gets

For the same reason that people can jump up and down and planes can fly: power. Gravity is not of infinite strength. If it were, we wouldn't be able to do simple things, like raise our feet to walk or lift a book to read. Gravity is powerful enough to ensure that things don't float around, but it's not strong enough to prevent them from leaving the surfaces on which they rest if an adequate force is applied to them. Only a small amount of force or power is required to overcome the force attributable to gravity -- also known as weight. A swimming dolphin can easily produce enough power to generate enough speed to propel it through the surface of the water and continue through the air for a few meters. Thankfully, gravity is strong enough to ensure that what goes up must come down. Once the dolphin can no longer propel itself, it falls back into the ocean.

dolphins are beautiful creatures which can save animals and humans. they are calm creatures that fight off sharks. goooo dolphins! from- purplishy

Pink dolphin is a mammal. They do not lay eggs. Only two mammals from Australia, lay eggs. They are platypus and echidna. They are the evolutionary link between eggs laying animals and mammals, which give birth to babies.

One or two dolphins take Aphrodite across the sea when she wants.

A dolphins brain and therefore its cerebral cortex is about the same size as a humans, however some dolphin species have a more deeply folded cerebral cortex than in humans but the cortex itself is not as thick. The level of folding found in the dolphins brain is so similar to that of humans as to suggest that they have a level of intelligence comparable to our own. So to answer the question what is the size of a dolphins cerebral cortex, the data seams to suggest it is about the same as our own.
