Can whales sleep standing up?
Whales can be terrifying creatures just because of how big they are. Many of us have only seen them on TV or through the glass of a giant aquarium. It’s hard to grasp their size and ours unless you’re up close our smallness. But besides their size, they also have some behaviors like their sleep patterns that still surprise, intrigue and even frighten us.
We know that whales are mammals and that they must come close to the surface to breathe, but did you know that they can sleep vertically? Imagine swimming and finding a group of whales in this position. Surely this is not a situation you would ignore. These animals are truly amazing and we are still discovering new things about them.
