       Dolphins jump, flip and dive through the sky and the blue ocean waters. These creatures are mammals, therefore they have lungs and not gills, and cannot breath underwater. Most people have seen a dolphin in a zoo or an aquarium.

          All dolphins live in the Pacific, Atlantic, or Indian ocean. About 75% of dolphins live in salt-water oceans. About 25% of dolphins live in freshwater streams. In either of these habitats, most dolphins live in the shallow part of the water. The reason for this is dolphins are mammals and do not have gills, therefore, they cannot breathe under water. They breath in oxygen They also live in warmer climates rather than cold ones. The reason for this is that dolphins prey of small fish and plankton live in warm waters rather than cold and, the dolphins biggest predator, the whale, lives in cold water and dolphins want to keep a distance from that.

Habitats 

 

     Dolphin babies are called calfs. Two years after the mother and father mate with each other, the calf is born. The mother dolphin feeds the calfs milk for two years and then the calf becomes a teenager and goes hunting with the family.

Dolphin Babies

 

         All dolphins have the same exact life cycle. The order goes, birth, becomes a calf, grows into an adult, mates or gets married, becomes pregnant, baby is born again and reproduction goes on and on. Dolphins have many names. Babies are called calves, women dolphins are called cows, men are called bulls, and a group of dolphins is called a pod or schools.

   

        Dolphins have many adaptations and skills. Some are walking on water, swimming 25 miles per hour, being able to leap 40-50 times in a row, and doing 14 spin jumps in a row. Trained dolphins can do flips, play ball, jump through hoops and so much more. Dolphins adapt to their surroundings by using the skills to keep predators away, and protecting their younglings. Dolphins breathe air through their lungs just like humans would. Dolphins breathe through their blowhole located at the top of their head and the blowhole is also considered the nostril of the dolphin. 

 

 

Skills and Adaptions


       Dolphins and humans have a very special relationship. Dolphins are healed when they are hurt by humans. Disabled humans can be helped by dolphins as well. Dolphins are trained by humans to do tricks such as flips, turns, jumps and so much more. We can also swim with and ride on dolphins. Dolphins and humans have a very great relationship, which makes studying them way easier because they aren't scared of us.

Human Interaction

 

        There are many stories about dolphins and their history. Dolphins are known to be magical because when they are leaping and flipping in the air and, it looks like they're flying. They can also make all humans happy because their face just has that effect on people and it makes them smile to know that they are not scared of you. They are also they only animal to play with humans and do tricks for them. Dolphins, especially the bottlenose dolphin, seem to smile at everything because dolphins are known to always look on the bright side of things and they never cry. 

Myths and Legends

 

      All dolphins have the same predators. And those are the Orca, the Killer Whale, the Great White Shark, the Tiger Shark and the Dusky Shark. They also are hunted by larger dolphins and humans. Dolphins are the most threatened species of sea animals in the world.

Predators

 

     All dolphins communicate the same way. They communicate through eco-location and sounds. Some of theses sounds include squeaking, cackling and shouting. 

Communication

      

      All dolphins eat small fish such as cod, anchovies, mullet, mackerel, and herring. They also eat Seals, Sea Lions, Squid and Killer Whales. They also feed on smaller dolphins and turtles too. They eat whatever is available in their current home.

Diet

 

        Amazon River dolphins are pink and are referred to as the Pink Dolphin. They live in the amazon river and can be found in the Madeira River as well. Pink dolphins are the smartest of the dolphin species and their brains hold 40% more  capacity of knowledge than humans. The Pink Dolphin is the most endangered species of dolphins in the world. Pink dolphins eat crabs, catfish, tiny river fish and sometimes small turtles. Pink Dolphins are the most friendly dolphin in the world and they aren't scared around humans, they are actually quite comfortable around them. 

The Amazon River Dolphin


       Pacific white-sided dolphins are shades light and dark grays and have black rings around both of their eyes. They weigh about 300 pounds and are 8 feet when they are fully grown. They live in the Pacific Ocean because, they do not like too warm or too cold waters and to them, the Pacific Ocean is a just right temperature. There are more than 50,000 Pacific White-Sided Dolphins swimming in the waters near Japan. A lot of them also live off the border of California. They can also be found in the Bering Sea. In the summer, they move into the waters around Washington and Oregon. They do many acrobatics such as enormous leaps, flips, somersaults, and surprisingly, belly flops. They mostly eat squid but they also can feed off of tiny fish such as herring, sardines, and anchovies. They eat during the night because the fish are closer to the shallower waters of the sea which makes them easier to catch and eat.

Pacific White-Sided Dolphins

 

        Long-beaked common dolphins are black or gray with a white belly. The weigh from 160 to 500 pounds and are 6 to 8.5 feet when they are fully grown. They live for about 40 years and they live in warmer and tropical waters such as the Pacific, Atlantic and Indian Oceans. They eat small fish such as anchovies, hake, pilchards, and sardines. They eat krill and squid too. This type of dolphin is not becoming extinct. However, they are being hunted for food by humans. This is ok because it is part of the circle of life.

Long-Beaked Common Dolphins

 

      Indian ocean bottlenose dolphins are gray and have black eyes. They grow 8.5 feet long, and grow to be 510 pounds. They live near the coast of India, Northern Australia, South China, the Red Sea, and the eastern coast of Africa. They eat tiny fish such as anchovies and sardines. This species of dolphins are not going extinct in any way which is fantastic news. Lets keep it that way.

Indian Ocean Bottlenose Dolphins

 

       Bottlenose dolphins are silver, white, and gray. They grow to be 6.6 to 13 feet long and they weigh 330 to 1400 pounds when they are fully grown. They swim 18 miles per hour. They swim at this speed because it is hard to swim more quickly when you are 13 feet long and weigh 1400 pounds and, they need to wait for their calfs so that they can teach them how to swim. They live in the Pacific Ocean and near the coasts of southern California, Japan, Chile, and Australia. They eat fish, squid and crustaceans. They can eat from 15 to 30 pounds of food each day. This species of dolphins is not becoming extinct but fishing nets are a big threat to this creature. Fishermen need to be way more careful to catch fish and not dolphins.

Botlenose Dolphins

 

     Fraser’s dolphins are gray and silver. They live mainly in the Pacific Ocean but they also can be found in the Atlantic Ocean as well as the Indian Ocean. They grow to be 6 to 9 feet and weigh from 350 pounds to 450 pounds. They eat shrimp, squid, octopus, and tiny fish. This species of dolphins aren't the most threatened species of dolphins but we still need to be careful about fishing on them because overdoing it means bye bye Fraser’s dolphins.

Fraser's Dolphins

 

      Dusky dolphins are black and white. They grow to be 6 to 6 ½ feet long and grow to weigh 150 to 187 pounds. They live mainly in the waters surrounding Australia, New Zealand, Africa, and South America. They eat shrimp, squid, anchovies and other tiny fish. To hunt they travel in groups of 300 so that the pray is surrounded and cannot escape. This species of dolphins is at risk of extinction because of fishing nets. Fisherman need to be more careful when fishing for fish because if too many dolphins get caught, this species of dolphins will go away forever.

Dusky Dolphin

 

        Hector’s dolphins are gray and white. They grow to be 1.5 meters in length. They are the smallest species of dolphins in the world. They grow to weigh 40 to 60 kilograms. They can only be found in the waters around New Zealand. They feed on tiny fish, squid, red cod, flatfish and yellow-eyed mullet. This species of dolphins is the most threatened species of dolphins in the world. Boat propellers and fishing nets are huge threats to this species. Boat drivers and fishers have got to be way more careful when out on the water because right now, 70% of theses dolphins are gone and we do not want them to become 100% extinct.

Hector's Dolphin

Hourglass Dolphin

 

      Hourglass dolphins are black, white and gray. They grow to be 5.9 feet long and grow to weigh 200 to 260 pounds. They live in the waters around Antarctica. They eat tiny fish, squid, and crustacean. This species of dolphins are not at any threat right now. Let's keep it this way.

 

      Peale’s dolphins are gray and white. They grow to be 2.2 meters and grow to weigh 115 kilograms. They live in the waters around South America and in the Atlantic Ocean. They eat mackerel, tiny fish, and herring. This species of dolphins has the largest population and is the most not endangered species of dolphins. This is really fantastic news. Let's continue to keep this species as not endangered as possible.

Peale's Dolphins

 

    Risso’s dolphins are gray, brown or white. They grow to be 10 to 13.12 feet and grow to weigh 660 to 1100 pounds. They live in the Atlantic Ocean, the Black Sea and the Mediterranean Sea. They eat cephalopods, krill, crustaceans, squid, and a variety of small fish. This species of dolphins is in fact, an endangered species. Right now 60% of these dolphins are gone. We need to keep the 40% of the living ones alive so that they can reproduce and continue to roam the ocean.

Risso's Dolphins

Rough-Toothed Dolphins

 

    Rough-toothed dolphins are gray, brown, or gold. They grow to be 6.9 to 9.3 feet long and grow to weigh 200 to 340 pounds. They live all around the world in deep, warm waters. They eat squid, octopus and a variety or small fish. This species of dolphins is not becoming extinct. They only reason for this is because of many wildlife protector research companies that are protecting them from harm.

 

     Spinner dolphins are gary or white. They grow to be 4.2 to 7.7 feet long and grow to weigh 51 to 170 pounds. They live in the Pacific Ocean and around tropical islands. They eat a variety of small fish and squid. This species is endangered because its main predator, all sharks, keep on devouring them by the minute. We need to separate the sharks from these dolphins or else these dolphins are going to be gone.

Spinner Dolphins

 

    Dolphins are an amazing species but we need to be more considerate about them because they can disappear at any time in any day. You can help by donating money to wildlife protector companies so that they can protest more about not hunting them. This creature will stay on earth forever as long as we do our part of not littering in the ocean and not fishing on them when we are old enough to do so.

     dolphins live

  • The Bottlenose Dolphin can jump 25 feet in the air and do 20 flips or spins before diving back into the water.
  • The Amazon River Dolphin can dive 900 feet in just 8 minutes.
  • A Spiner Dolphin can spin 30 times, 30 feet above the ocean before diving back into the water. That's higher than a double-decker bus. That's why they are named "Spiner Dolphins''. 
  • The Indian-Ocean Bottlenose Dolphin can hold their breaths under water for 8 minutes but any longer and they will drown. 
  • The Pacific White-Sided Dolphin can flip 25 times in the air before diving back into the water. 
  • The Pacific White-Sided dolphin can dive 900 feet into the water in8 minutes but any longer they will drown.
