River Dolphins are a dolphin that have swam to a river and decided to live there. All the dolphins moved because of the water is very hot and the air is very cold. Two people went out in the river on a speed boat to try and spot the dolphins. The first one they saw was right next to a cargo ship swimming and it sounds dangerous but it is safer than them being next to a speed boat.
And the dolphin expert thought they shouldn’t be living there because there is lots of polution and lots of buildings that prouduce polution which is not good for the dolphins because they could die if some wrapper got around it’s neck.
