Whales' front limbs are called fins. Only some whales have back limbs, which are very small. The tail is divided into two extensions called flukes. Most whales also have a dorsal fin.
The rear flippers of a whale are called flukes. They are broad and flat, and are used for propulsion and steering while swimming.
The Blue Whale has a small Dorsal Fin as well as its Flukes (tail) and its Flippers.

A whale's tail is called its flukes. The flukes are used in swimming
Whale tails are called flukes because the term "fluke" refers to the broad, horizontal lobes of a whale's tail, which are used for propulsion in the water. The word originates from the Old Norse word "floka," meaning "to float," and has been used in nautical contexts to describe similar shapes in other marine animals. The distinct shape and functionality of the flukes allow whales to navigate and dive efficiently.
