Someone I know said that a friend of his had spoken of penguins as being frightening creatures. He was puzzled by this and upon questioning him realized that he thought that penguins were large animals, roughly the size of an adult human.
I realized that I too had thought of penguins as being larger than they really are. This was even though I had seen penguins in the wild in New Zealand. But those were known as ‘fairy penguins’ and so I assumed that they were a variation that was unusually small. In reality, most penguins are only around two feet in height though the very largest penguins, the Emperor Penguins, can reach heights of about 3.5 feet.
Maybe this misperception is because when we see photographs of penguins, they are usually in the Antarctic surrounded by other penguins and so we have no scale by which to judge their size.
But here is a video of a penguin that seems to have formed an attachment to a human and we get a sense of how small they really are. But quite fast, it seems. And very cute.
