Why are killer whales fat?

Killer whales are not typically considered "fat." In fact, they are highly athletic predators that are streamlined and muscular. Their bodies are built for speed and agility in the water.

Here's why you might think killer whales are fat:

* Blubber: Killer whales, like many marine mammals, have a thick layer of blubber beneath their skin. This blubber helps them stay warm in cold waters and provides energy reserves. It might look like a layer of fat, but it serves a critical function for their survival.

* Size: Killer whales are large animals. The largest species can reach over 30 feet in length and weigh over 10 tons. Their size can make them appear bulky, but it's a result of their muscular build and the need for a powerful body to hunt large prey.

* Diet: Killer whales are apex predators, meaning they sit at the top of the food chain. They eat a wide variety of prey, including fish, seals, sea lions, and even other whales. Their diet is rich in calories, which contributes to their muscular mass and blubber reserves.

Overall, killer whales are not fat. They are well-built animals with a healthy body composition that is perfectly adapted for their environment and lifestyle.
