yes they have the biggest fin called the dorsal fin
yES THEY DO CUT THE FINS IN THE KILLER WHALES IN THE TUNDRA
They cut it with a knife
teeth, fins, skin, a heart, and a Head
dorsal fins dense, fibrous connective tissue, with no bones or cartilage
Orcas, also known as Killer Whales, have dorsal fins. Beluga whales do not.
A survey documented wild males orcas have fins bent. No one is exactly sure why the dorsal fins of killer whales bend, but it may have to do with genetics, injuries, or because the fins can be taller than many humans without any hard bones or muscles for support.
Killer whales do not have feet, they have a fins at the back of them and a dorsial fin on their back :) hope this helped :P
Killer Whales are actually dolphins. They are the largest member of the dolphin family.
Generally Killer Whales (They aren't actually whales.) in packs can take down the largest whales. Sharks can feed on whale calves and other small whales.
mammals evolved fat, lost tails, legs turned into fins etc.
Killer Whales prey on Grey whales, which are quite big.
Killer whales have distinctive black and white markings. In the wild, their dorsal fins are usually very tall.
