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. =)

This has all of the information that you should need.\n\nhttp://en.wikipedia.org/wiki/Dolphin\n\nGood luck!

I know for a fact that besides humans, dolphins choose a partner (male or female) who they will be with for the rest of their lives. Normally the males make the decision, and when one chooses a female, he will spend his life with her and only mate with her, but if he chooses a male, he will spend his life with him like best friends, and during mating season they will go look for female to reproduce. When one dies, shortly the other one dies too (could be the same day, or even days or weeks after).

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.

There are over two million species alive on earth right now. Which particular path do you want?\n\nFor humans, we know the progression through some crucial stages, but not the whole thing. For example, we have very good fossils for the transition between certain fish and amphibians, between reptiles and mammals, very good evidence for the last couple of million years. The early development of primates is being actively researched with a lot of interesting results.\n\nHere is the basic progression:\nLife started about 3.8 billion years ago\nEucaryotic life (with true nuclei) started about 2 billion years ago.\nMulti-cellular life started about 570 million years ago.\nThe first vertebrates were around 450 million years ago.\nThe developement of sarcopterygian fish was about 400 million years ago.\nDevelopment of labrynthodont amphibians from the sarcopterygian fish was about 360 million years ago. \nFirst reptiles from amphibians was about 320 million years ago.\nA wide variety of mammal-like reptiles developed in the time period between about 300 million years ago and 250 million years ago, with the cynodonts developing later. \nSmall, rodent-like mammsls developed from the cynodonts about 220 million years ago.\nSome very early primates developed around 60 million years ago from smallish rodent-like mammals.\nHomonoidae (apes) developed around 22 million years ago with Proconsul the type species.\nDryopithecus was around 17 million years ago in Africa and was an ancestor to most african apes.\nAustralopithecus developed about 4 million years ago in Eastern africa with Australopithecus afarensis the most likely human ancestor.\nBetween about 2 and 3 million years ago there were several hominid species in eastern and southern africa. The exact human ancestor is controversial since they are so similar.\nHomo habilus appeared about 2 million years ago and was replaced by Homoe erectus about 1.5 million years ago.\nHomo sapiens (modern humans) appeared about 300 thousand years ago in africa. There were other hominid species around at that time and later. For example Homo neanderthalensis was around until about 25 thousand years ago. Whether Neanderthals contributed to modern humans is another controverisal question.\n\nIt should be pointed out that the exact ancestral species may not be known. But it is typical for a variety of closely related species to develop in the fossil record at the same time. Figuring out which one is the actual ancestor for a given later species is not always possible given the fragmentary fossils available and our current knowledge of how structural changes occur in evolution.\nI hope this helps.

There are pink dolphins in the Amazon region (boto cor de rosa, in Portuguese). They are rarer than the other kind of dolphins found there (Tucuxi).\nThe most famous and interesting story about these dolphins is that they are often blamed for making the young girls pregnant in the region. According to the legend, at night they turn into handsome young men, to which the ladies immediately fall in love.

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

Dolphins live in a tribe.There can be up to 150 dolphins in each tribe.The mother is the centre of the family.\n\nWhen hunting they use a method called "Kettle technique".\nThey manage to gather the fish together into a ball shape by letting out piercing cries and by surrounding them with bubbles. In this way it is very easy to catch them.\n\norcas work in co-operation with one another, swimming in unison to create a wave pattern in an attempt to knock the seals off of the ice. This clever hunting technique quickly and efficiently could provide dinner for a pod of orcas.\n\nI once read about a incident where the orcas followed a young blue whale and its mother for 4 days and when it got exhausted they had eaten it.The mother was too big for them and they could possibly not harm it.

Either a slick shark or a dolphin. Sharks are amazing creatures which live for hundreds of years and dolphins are just awesome

We have catalogued an estimated less than half the species out there- And once catalogued, we don't have an active system to determine populations of most species.  Thus, we are in the dark about what species are there, how many there are in the population, etc.  GIven that, we have only vague guesses about the number of species lost.  In a similar vein, we assume new species are being born each year, or at least each decade, but since we don't know what species were there before, we certainly can't tell if a species is newly evolved, or is just one we have never seen before.

Some of them are, including the Common Dolphin in Greece, Hectors Dolphin in New Zealand.

There are estimated 5,000 to 12,000 blue whales left. There are groups in the North-East Pacific, Antarcic, Indian Ocean, and at least two more large groups in the North Atlantic and more in the Southern Hemisphere.

Every day, about 5 species die out. :-(

.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
