My Bibliography http://www.greenpeacefoundation.org/ Pink dolphins live in the mouth of the Amazon River, in fresh water!! When do dolphins breed? Dolphins tend to breed in the summer so it's not too cold for their babies because they are pregnant for a year. Dolphins can live up to 40 years old. Fish is a staple of their diet, but they also snack on other small animals. Pink dolphins live up to 30 years. Dolphin Research Dophins don't have vocal cords so the muscles in their blowhole makes squeaks, moans and other sounds using their blowhole. They're able to move because of the up and down motion of their flukes. To be able to find where their prey is in the murky waters they send out high pitched sounds that bounce off the object. From just having that, they are able to determine the animals size, shape, and how far away they are. Thanks for watching my prezi :)
