Irish dance bears are adorable.
They dance in the sun and have amazing eyes.
In fact, they look like a baby bear, but they’re actually quite big.
They weigh more than a quarter of a tonne and are able to jump high and slow down.
This might be due to their large muscles, but there’s more to the story.
It turns out that their muscles and bones are really good at storing energy.
They’re very light and fluffy and have incredibly dense tissue, which means that they are very efficient at storing and releasing energy.
In the past, scientists have looked at how these animals store energy in their muscles, and they’ve concluded that the muscles of dance bears, the one pictured above, store energy as glycogen, which is the stored form of fat.
This is why dancers who can’t perform for longer than five minutes are often referred to as “fat belly dancers”.
These dancers also use their muscles for other things, like for balancing, walking, and swimming.
And these animals are really cute.
