Okay, so you know how whales are those big animals that live in the water? Well, sometimes these whales can get lost or separated from their families or groups, and they end up swimming all by themselves. When this happens, we call it a "drift whale."
A drift whale kind of just goes with the flow of the ocean currents, which means it doesn't really have a specific direction or purpose in its swimming. It just keeps swimming along wherever the water takes it.
Now, this might sound kind of sad or scary for the whale, but don't worry! Drift whales are usually just fine. They might have a harder time finding food or other whales to be with, but they can still survive on their own for a while.
Sometimes, people try to help drift whales by directing them towards areas where there might be more food or other whales. But for the most part, drift whales just have to keep swimming and hoping that they'll find their way back to their families or groups someday.
