  • 2. Their Body Parts• Dolphins have many body parts but many people do not know the realnames of them. Can you name them all?
  • 3. Facts• There are 36 species of dolphins found in the world.There are 32marine dolphins, and 4 river dolphins. They live mainly in saltwatersuch as the oceans but some of them live in freshwater and they areable to do very well there. They tend to live in the shallow water by thecoast and they tend to live in warmer locations. The name dolphincomes from the word womb, and it is believed to be the Greek sayingfor fish with a womb You may hear dolphins referred to by variousnames. The young are called calves and the female adults are cows.The male adults are bulls and a group of them is often called a pod.Sometimes, you may hear them referred to as school.
  • 4. factsThe distinctive populations of them stem from the DNA code. What hasbeen noted is that the different species have vary different codeswhich sets them apart from each other far more than researchers hadoriginally believed. The DNA code is how a discovery was made thatidentified a separate species of dolphin than what had been looked atbefore.In 2011, a new dolphin’s species was found in Big City Harbor aroundAustralia. The Burundian Dolphin is believed to be only in two areas atthis time. There are about 100 of them in Port Phillip Bay aroundMelbourne and about 50 more of them in the coastal lakes ofGippsland which is about 100 miles away.Studies also indicate that there are differences among the species ofdolphins in terms of their skull size and design. When they are lookedat closely, there are slight variations that have been noted. There aresome other differences too including some having a curved dorsal fininstead of straight and changes to the snout. Here is some informationabout some of the commonly known species. It can be an interestingthough to take one at a time and learn more about them.The type of dolphin you will see in a given area depends on environmentalfactors such as enough food and the temperature. The time of yearalso is a factor due to the heavy migrational efforts of most dolphins.Perhaps the most common of all dolphins is the Bottlenose Dolphin.This is the one you often see in books, movies, and when you visit anaquarium. They are very intelligent, easy to train, and they are morelikely to approach humans in the wild than other species.

This is the one youoften see in books, movies, and when you visit an aquarium. They are veryintelligent, easy to train, and they are more likely to approach humans in thewild than other species.River Dolphins live in freshwater, and they are found in a variety of riversaround South America and Asia. They are smaller than most dolphins, withan average size of about 8 feet when fully mature. They can be variouscolors too including brown, gray, or black.The Roughed Tooth Dolphin is harder to spot out there in bodies of water because they prefer the deeper locations. Theycan weigh about 350 pounds and measure about 8 ½ feet long. They have a small head and feature a long beak. Theyare also lacking the common crease on the melon that other dolphins have.

  • 7. facts• The square shaded head of the Risso Dolphin is a telling sign of whatspecies you are seeing. They don’t have any teeth in the upper jawbut they have several peg like teeth on the bottom jaw. They arefrequently found in captivity on display because they thrive in such anenvironment.The Striped Dolphin gets its name from the blue and white stripes on thebody. This species is believed to have the highest population as wellas the biggest overall distribution of that population. If you want to beimpressed by acrobatics, check out the Spinner Dolphin. People loveto see them perform both in the wild and when they have been trainedin captivity.The Common Dolphin is very simple in design, but also very respected inthe early cultures. Researchers have found items from the AncientGreek and Roman times. The Dusky Dolphins tend to live in waterthat is cooler than the temperatures for other species of dolphins.They can be found along the coastal regions as well.The Killer Whale is believed to be the most powerful of the dolphins due totheir size and their strength. They can take down seals effortlesslywhich is important due to the significant volume of food that they canconsume on a daily basis.  The Pilot Whale can weigh up to 5,000pounds and be up to 24 feet long. They are believed to be the mostsocial of the dolphin species. They are also very vulnerable to
