What Is the Tail of a Whale
A whale tail, called the fluke, is the broad, flat paddle at the rear of the body. It is made of tough connective tissue, not bone, and is used for propulsion and steering.
How the Tail Moves and Functions
Whales move their flukes up and down to push water backward and swim forward. The tail stock connects the flukes to the body and flexes to control direction and speed.
Why the Tail Matters for Identification
Fluke patterns, scars, and color markings are unique to each whale. Researchers use tail photographs to track individuals, study populations, and monitor migration.
