The ocean is very large and full of salty water. Whales and many other animals live here. Whales are very big, so they need to live in a big area. There are many different kinds of whales. Many of them eat a very small animal called krill. These animals look like shrimp.
Lakes are very different from oceans. They are much smaller and the water is not salty. Plants and animals live in lakes, but they are not the same as plants and animals that live in the ocean.
Some whales visit lakes, but they can't live there because lakes are too small. Lakes also don't have krill for whales to eat.
