King of Beasts 狮子

Even skywatchers connect lions with royalty 1. For example, the brightest star in the constellation 2 Leo the Lion is called Regulus -- which means "little king." Discover why lions are said to be the king of beasts -- today on Earth and Sky.

JB: This is Earth and Sky, with a listener's question. He writes, "Why are lions sometimes called 'the king of beasts'?"

DB: People have made this association for a couple of thousand years at least. But lions are not the biggest of animals -- and they're not the strongest. A lion would fit into the mouth of a blue whale. And, even among cats, the tiger is more powerful than the lion.

JB: Adult male lions look regal, with flowing manes framing their faces. Not only does this long, thick fur soften 3 an enemy's blows, it also makes a lion's head look bigger -- perhaps giving it an appearance of being "crowned." The lion's roar is impressive, too. Lions roar to define their territory -- and the thundering sound can be heard from several kilometers away.

DB: And some might say that a lion lives a life "fit for a king." Lions typically sleep for about 20 hours a day. Unless it's provoked, a lion's leisure is usually only interrupted by the hunt for food -- most often, a zebra or wildebeest. After a fierce battle, lions will feast until full -- sometimes eating up to 75 pounds of meat at one meal!

JB: And here's another way lions are king -- they're pretty much at the top of the food chain in the plains of Africa where most of the wild lions live today.
