yES THEY DO CUT THE FINS IN THE KILLER WHALES IN THE TUNDRA
Animals that use fins to move are whales, dolphins, sharks, and various types of fish. A fin will generate thrust and propel the animal through the water.
Sharks have straight dorsal fins, dolphins have curved dorsal fins and whales don't have dorsal fins :)

No, they are called Megaptera Novaeangliae, (Latin) or long winged New Englander, by the whalers for their very long pectoral fins, the longest fins of any whale.
Orcas, also known as Killer Whales, have dorsal fins. Beluga whales do not.
Some do. For example, dolphins and whales are marine mammals and they have fins.
