Stephane Granzotto, a French photographer and filmmaker, was looking at sperm whales in the Mediterranean sea for his photo book on wildlife when he came across something unusual. It is the sleeping pattern of these whales. Granzotto discovered this while working on his photo book.
These animals rest in a vertical stance deep within the ocean, giving the impression that they stand when observed from the surface. Nobody knew how they slept till research in 2008 revealed it, and nobody had seen or photographed this before this photographer.

According to an article in National Geographic, when they are in this position, they take deep breaths and sleep almost 45 feet deep under the ocean. And when they sleep, they do it in groups of five to six whales called pods, slumber for around two hours at a time.
