They bash into their predators. they are actually quite strong. they kill sharks that way

Dolphins are being protected now, and are growing in numbers again, and they seem pretty happy when I use to see them! But im not a dolphin, yes yes...believe it or not...I'm not. =)

What is the difference between a dolphin and a porpoise? I heard this question asked, on Johnny Carson. And, Johnny decided that a dolphin was a mammal, and a porpoise was a fish. Wrong. They are both mammals, and are very closely related. The porpoises have a rounded head, while the dolphins have a protruding snout. They are smaller members of the toothed whale family, to which killer whales and sperm whales belong.\n\nTo complicate things, there are a couple of fish which are also called dolphins. I assume that these are sometimes called "dolphin fish" to avoid confusion. But, the well-known dolphins are those cute mammals, like Flipper (who is a bottle-nosed dolphin).\n\nMammals have hair, breath air, give birth to live babies (platypuses and echidnas lay eggs), and feed milk to their young. Whales breath air (they can hold their breaths for long times), give birth to live babies, and feed milk to their young. Where is their hair? Evidently, they have a small amount of hair around their blow-holes, those holes, in the top of their heads, that they breath through.\n\nThe toothed whales are among the most intelligent of all animals. The killer whale (orca) apparently has a brain mass to body mass ratio (a rough measure of intelligence) which is greater than that of humans. Incidentally, while toothed whales are predators, there is no record of any killer whale ever having killed a human being.

In a way--when they get beached, however that happens(I'm no scientist), the sheer weight of their bodies suffocates them, gradually.  The whales weigh so much, only water can support their bulk.\nI wish this were  not so, but it happens.

they are mammals so they breathe air

It will vary from dolphin to dolphin. Certain dolphins will prefer different rewards over others. That is why dolphin trainers learn the personalities of the dolphins to see what they like as a reinforcement. Just like dogs, they preference over certain things.

Especially for you is a background and proven history of bottlenose dolphins:\n\nBottlenose dolphins feed mainly on Eskimos and bearded Eskimos. Depending upon their location, they also eat juvenile Eskimos and hooded Eskimos and scavenge on carcasses of Eskimos. Might I also point out that it is a little known fact that dolphins can walk and breathe on land. When Eskimos are unavailable, bottlenose dolphins eat Eskimo berries, and Eskimo garbage. A bottlenose dolphin's stomach can hold an estimated 15% to 20% of its body weight meaning it can eat an entire Eskimo. It can assimilate 84% of the protein and 97% of the fat it eats. Bottlenose dolphins need an average of 4.4 lb. of fat per day to survive, so your average obese Eskimo will suffice. An Eskimo weighing 121 lb. could provide up to eight days of energy for a bottlenose dolphin. \n\nHunting Methods \n\nStill Hunting:\n\nThe bottlenose dolphin remains motionless beside a front entrance to an igloo waiting for an Eskimo to exit. When an Eskimo exits, the bottlenose dolphin bites onto the head or upper body, then flips the entire Eskimo onto the ice. \n\nStalking on Land:\n\nOnce spotted, the bottlenose dolphin slowly and steadily stalks the Eskimo. At 15 to 30 m away, the bottlenose dolphin suddenly charges the Eskimo, with its teeth; the bottlenose dolphin grabs the Eskimo before the Eskimo can enter his igloo. \n\nAquatic stalk:\n\nThe aquatic stalk is a method also used in summer when Eskimos sunbathe on sea ice. The bottlenose dolphin swims toward a hauled-out Eskimo. Once the bottlenose dolphin reaches the ice edge, the bottlenose dolphin quickly emerges from the water and grabs the Eskimo with its teeth.\n\nStalking birth lairs: \n\nStalking Eskimos at their birth lairs is a hunting method bottlenose dolphins use in spring, when Eskimos give birth to their young. Eskimo birth lairs are caves built under snowdrifts next to a hole in the ice. The snowdrifts are on stable sea ice attached to land. Once a bottlenose dolphin identifies a birth lair, it slowly and quietly positions itself next to the lair. If a bottlenose dolphin smells or hears an Eskimo in the lair, it slowly rises up on its hind flippers and crashes down with its flippers to break through the lair roof. To break the roof's hard surface, several tries are sometimes needed, which may allow the Eskimo to escape to its sled. This method is most commonly used by bottlenose dolphin females with pups under one year old.\nMother Eskimos and their young have the high fat content needed for hungry bottlenose dolphin mothers and their growing pups. Male bottlenose dolphins that may attack young bottlenose dolphin pups don't normally hunt Eskimos in birth lairs. Birth lairs are usually on sea ice attached to land, allowing young Eskimos (who have little protective blubber) to avoid crossing water.\n\nInteresting Bottlenose Dolphin Facts\n\n1. Bottlenose dolphins are very sarcastic. \n2. In 1931 Hollywood was scandalized by Fatty Arbuckle's affair with Fru Fru, a (married) bottlenose dolphin. Neither Arbuckle nor FruFru's career (she was an ice-dancer) survived the media backlash.\n3. Many people assume that bottlenose dolphins are mammals. They are in fact a form of fruit resembling a banana.\n4. Just as Jews are often blamed for catastrophic events in the global community, so bottlenose dolphins are often blamed for disaster in the arctic community. Because of this, many bottlenose dolphins refer to themselves as jewdolphins.\n5. Famous musical bottlenose dolphins include Jimi Hendrix, Larry Adler, Cyndi Lauper, Jeff Beck, and of course Bottlenose dolphin.\n6. In 1914 the bottlenose dolphin population of London was 12. It is now 15.\n7. Bottlenose dolphins have the most natural rhythm of all the arctic animals. During spring and summer, bottlenose dolphins often give synchronized swimming classes to students in Brazil. \n8. If you are very sad and very lonely, and you think hard enough about a

Dolphins have the vocal capabilities to talk like humans and communicate with us. It's true.

People like dolphins because they are extremely intelligent and also they are able to harm the much hated shark. The noises they make are both high pitched and somehow friendly/playful. Because they interact with humans in a playful manner, it is easy for most people to grow attached to the sweet looking creatures.

.WHALES AND DOLPHINS:\n\nWhales and Dolphins are marine animals. They live in oceans around the world. Whales and Dolphins come from the same family, CETACEA (sey-tay-sha) . They both breath from a blowhole located at the top of their head. Whales and dolpins are mammals. They are mammals because they have lungs not gills,they have hair not scales , and they also have give live birth and don't lay eggs. There are only about 80 kinds of whales and dolphins that we know of right now.\n\nWHALES:\nWhales are very large animals. They can grow up to 100 ft. or more in length. They can weigh up to 200 tons or more. Whales live in families called pods. These pods vary in numbers and consist of family members and family friends. Whales live in these families their whole life. Group living is safer when other whales or sharks attack. It also makes it easier to find food. Whales are always migrating. They travel to find food, breed and have young.\nWhales do not have eyelids. They rely on thick oily tears to protect their eyes. Whales hear from little holes behind their eyes.\n\nWhales talk to each other by making high pitched sounds like whistles, clicks, squeaks, rattles, and groans.\n\nTo help protect the whales from extinction please DO NOT throw nets, fishing lures, or other fishing gear ocean\n\nDOLPHINS:\nDolphins live with the whales in the oceans. But dolphins come much closer to the shore. They will come as close to the shore as you or I can walk without going under water. Dolphins have teeth.\nLooking at a dolphin you would not think it as a nose, but surprise...it does! They have nostrils called blowholes. Over millions of years of evoloution whales and dolphins nostrils moved to the top of their head. This allows them to breath by surfacing instead of them sticking their whole head out of the water.\nThe first thing a newborn dolphin must do is to go to the surface to breathe. But the baby can not swim so its mother and a another dolphin will help push the baby to the surface for its first breath of air. The baby will be able to swim in about 30 min.\nDolphins are fast swimmers. When a speeding boat passes the bottlenose dolphin, it will start to race out in front . They will take off hitting the water and keep going.\nDolphins navigate by following the hills and mountains of the ocean floor, by tracking the sun, by sensing currents, and by tasting the water along the journey.\nA dolphin's sound probably originated in its nasal passages. These nasal passages are located on the top of the head. Dolphins can make sounds to see what lies ahead. This sense is called echolocations. The dolphins' sound waves hit an object and the echo bounces back. Echolocation sounds are called sprays. Sprays are so strong they can stun another whale. Dolphins don't "point" their melons at any other sealife except their enemies.\n\nSHARKS:\nOut of all the species walking, flying, slithering or swimming, there aren't many who have been around as long, survived as well, or come in so many shapes and kinds as the shark. The earliest evidences of sharks are isolated spines, teeth and scales that appeared about 430 million years ago in the Silurian Period, known as the "Age of Fishes". Sharks have a sleek, streamlined design which helps them swim without using up a lot of energy.They certainly need to conserve their energy because they never really sleep and most of them never stop swimming.\n\nSome sharks are fierce predators, and would be happy to eat you if they encountered you. Almost any shark six feet or longer is a potential danger, but three species have been identified repeatedly in attacks: the Great White Shark, the Tiger Shark and the Bull Shark . All three live world wide, reach large sizes and eat large prey such as marine mammals or sea turtles. But most sharks never grow longer than five feet and never even see anyone with legs and arms anyway. People kill thousands more sharks every year than sh

All species of dolphins use sound for echolocation. Using their melon (the bulbous portion of their forehead), they create a sound that bounces off objects around them. The returning echo of the sound gives the dolphin information about the location and physical description of the object. I don't know much about the actual workings of the brain though, but I do know that the dolphins sonar is much more advanced than human technology and can pin point exact information about it's surroundings ranging from size, distance and even the nature of the object. Dolphin Speech is so complex that the sounds even cross the species barriers and enable different kinds of dolphins to communicate.  They have been known to instruct each other as well as receive instructions and act accordingly.

Most mammals are able to swim if they absolutely have to.  It's true that some might drown while attempting to, but that doesn't mean that the species itself can't swim.  Dolphins and seals sometimes drown too, but no one would say they can't swim.\n\nHow well a particular species of mammal can swim depends a lot on their physiology.\n\nAnimals with higher density of muscle than fat tend to sink instead of swimming.  Even if they have the limb mobility and strength that should be allow swimming, they have tremendous difficulty keeping above water.  Most primates actually fit into this category.  Chimpanzees in particular tend to sink like a stone in water, and avoid swimming at all costs.  Humans are very unusual in their ability to swim, and affinity for water (which raises a whole other set of questions, but that's another topic).\n\nIf they don't have much fat, thick fur can also help keep a mammal afloat.  Dense underfur traps air and can act like a flotation device.  Baby sea otters actually have difficulty diving because their fur traps so much air that they can't swim hard enough to reach the bottom.  Once again primates, with their thin, sparse coating of hair lose out on the flotation front.\n\nAnother factor is limb mobility.  Critters that can't move their arms and legs as swiftly or don't have enough surface area to push water aside tend to be crappy swimmers.  Anteaters tend not to be great swimmers, and camels aren't likely to win any swim meets either.\n\nIn general, mammals are pretty good swimmers.  Most mammals have some fat, most of them have hair or fur to trap air, and they have the limb mobility to move around.  Mammals can also close their mouths or noses and block their breathing passages so they don't take water in.  Critters like insects and spiders don't have that option, and unless they have other adaptations they tend to drown fairly easily.

It's not just humans - most mammals (and other animals to a lessor extent) have emotions.  They serve many key functions for survival:\n\nThey give a reason to act.\nThey give a reason for animals to attract each other.\nThey imprint important experiences in the brain.\nThey help animals make decisions.\n\nThere's probably more, but that's a good start.

If you consider evolution, any animal that is able to protect itself will. They would have only adapted the ability to fight off enemies or hide from them if it was something that they used and it saved their lives. The only "passive" animals out there are the ones who don't have the ability to defend themselves. So to answer your question, no, there are no animals who naturally choose to not protect themselves when they are capable. Only on an individual basis could this happen. There are no known species or populations that do that.\n\nThe sloth is endangered because we cut down its trees that keep it safe. Frogs don't let animals eat them, they try to run away. The closest thing to what you are describing that I can think of would be a mother duck pretending to be injured to lure the predator away from the chicks. Of course, when she gets it away from the chicks, she too flies away.

Land animals can walk on land and breath oxygen. With the exseption of dolphins and whales the others cant breath oxengen.

Probably loyalty. A dog is the only animal that will protect you. They do actually love their owners/masters and apprectate the food and shelter you provide. They reward you with loyalty.
