The fins on a dolphin, whale, shark, basically all marine life, have evolved in such a way as to exemplify their strengths. A dolphins strength is to be fast and agile. Their fins help them to navigate the waters in the most energy efficient maner. Their flukes (tails) are incredibly strong and help to propel them through the ocean/lakes/and rivers. Also the dolphins fluke moves up and down, not side to side like a shark.
