You see dolphin whistles are about the same frequency as the boat motors. What a lot of work. More at Ms. Frampton's DE school site Ms. Ripley Today was the last day of my expedition, but I have an important story to share with you. There is a dolphin that spends most of his time in an inland waterway. Beggar follows each boat long enough to see if someone will feed him.
Dolphins are smart.
We noticed that Beggar only went to the boats that were small enough to be able to reach the water from the sides. Large boats with high decks never got a visit from him. He has learned this behavior over time. Watching this beautiful animal was really very sad. His interactions with humans have changed his natural behavior.
