2: Olivia Scott 6/10/2011 Mr. Mungin Science Amazon River Dolphin Meet the Amazon River Dolphin Have you ever seen a PINK dolphin before or a dolphin that can swim through trees? Do they even exist? Well, they do! These dolphins are called the Amazon River Dolphin. There's a lot of interesting qualities of this dolphin, but first let me tell you more about this amazing dolphin. One thing is this dolphin has like 1,000,000 different names but the most common are the Amazon River Dolphin and the Boto Dolphin. Its scientific name is Inia Geoffrensis. The Amazon River Dolphin's life span is 15-30 years because of endangerment. One thing you might not know is dolphins and whales are mammals just like us.What makes them mammals are they breath air,their young

3: are born live, they are warm blooded, and they have hair. Dolphins have blowholes that they breath out of. The Amazon River Dolphin is a toothed whale. Yes, dolphins are whales. This dolphin has very sharp teeth and a long beak for hunting their prey. A neat thing about this dolphin is it has over 100 teeth in its mouth. Characteristics An Amazon River Dolphin is normally 6ft and 6in to 9ft long and are about 175-285lbs. They're the biggest river dolphins alive. Its dorsal fin is different from regular dolphins. Regular dolphins have a curved dorsal fin like in the picture to the right, but a river dolphin has a hump like dorsal fin. A dorsal fin is a fin on the dolphin's dorsal side (dorsal side is the top side of the body). As I mentioned before the Amazon River Dolphin is pink. The reason why this dolphin turns pink is because while the dolphin is growing up its blood starts to flow closer to its skin causing it to turn pink. The dolphin turns pink during its life span. When it is born it's a light gray then when it becomes mature it turns pink. Its flukes (or tails) are broad and have

4: ragged trailing edges, and a distinct notch in the middle of the fluke. The Amazon River Dolphin, like all dolphins, have a melon (the top of its head). One difference between a river dolphin and a regular dolphin is a river dolphin has a bigger melon. Scientists don't know exactly what its for, but they believe its for echolocation. The Amazon River Dolphin also have very, very small eyes. Their eye sight is poor but they are able to hunt with it. Behaviors One of the behaviors this dolphin has is popping it's melon up and down in the water. It also does a little spy hopping. Like a normal dolphin it also likes to do flips and jumps out of water. The Amazon River Dolphin uses echolocation to communicate with other dolphins. It also sings a little. Family LIfe Dolphins live in pods, or groups. One pod is around 2-15 family members. The Amazon River Dolphin breeds in warm waters. When a calf is born it has thick blubber (blubber is fat that keeps the animal warm). A female Amazon River Dolphin is pregnant between 9 to 12 months. She should only have one calf. When the calf is born, the parents separate and

5: the calf is left for the mother to take of. The mother will teach the calf how to hunt and swim. Once the calf has learned how to survive and is mature the mother will leave it with its new pink look. Habitat The Amazon River Dolphin lives in the rivers of the Amazon Rain Forest. They swim through the rivers hunting for their next meal. When the rivers overflow the dolphins migrate up to the trees. In the rain forest the water level is pretty high once it rains so this helps the dolphins start swimming through trees hunting for their pry. Diet The Amazon River Dolphin's diet includes over 50 different fish, turtles, piranhas, and other creatures living in the sand. Researchers found that their favorite food is catfish and piranhas. No one knows how much this dolphin eats a day but we know they eat at least 15 piranhas per day. This dolphin has tiny hairs in its body that helps it sense things in the sand, once

6: a creature is found the dolphin will use its fins and flippers to dig into the sand. Endangerment One really sad thing about this dolphin is it's endangered! No one knows how many are left because people are hunting them. Some reasons this dolphin is endangered is people hunt them for their meat and oil (yes, I said oil). Their habitat is also being taken away leaving them with nowhere to go. Believe it or not the dolphin's enemies are us, humans. The Amazon River Dolphin is protected in some South American countries. To help save this wonderful dolphin, people are banishing hunting and are making reserves for them. Help save this amazing animal. Well, that's really all you need to know about this dolphin. If you are interested in this dolphin please try to help save it. It is a very cool and amazing dolphin and it would be really sad to see it become extinct. I hoped you like learning about this fantastic dolphin!
