What does a killer whales tale look like?

A killer whale's tail, also called a fluke, is large, powerful, and uniquely shaped. Here's a breakdown:

* Shape: The fluke is a crescent-shaped, horizontally flattened structure.

* Size: It can be up to 6 feet wide and 5 feet tall.

* Color: It's typically black on top and white on the underside, with a distinctive white patch on the dorsal side of the fluke.

* Function: The fluke is the primary means of propulsion for killer whales. They use it to generate powerful thrust for swimming, jumping, and turning.

* Variations: The shape and size of the fluke can vary slightly between individuals, and even more so between different populations of killer whales.

Here are some additional points to remember about a killer whale's fluke:

* It's made up of cartilage and muscle, not bone.

* It has a complex network of blood vessels that help regulate its temperature.

* The pattern of black and white on the fluke is unique to each individual, much like a human fingerprint. This can be used by researchers to identify individual whales.

Overall, a killer whale's fluke is an impressive structure that plays a crucial role in their survival and success.
