Have you ever seen a penguin on TV, in a magazine, or in a zoo and asked yourself – are penguins mammals? This is a pretty common question and the answer is interesting as well. One reason why many people think that penguins are mammals is that penguins spend most of their time on land or in the sea. So, what is the right answer?
Are penguins endangered? This question must have arisen in your mind whenever you looked at the cute and cuddly penguins in a zoo or on the television. Well, the answer is not that simple. According to the International Union for Conservation of Nature (IUCN), there are five species of penguins that are facing extinction and seven species are listed as vulnerable. The remaining species of penguins are at different levels of endangerment.
Do penguins have knees? Looking at a penguin, this is one of the first questions to arise in a person’s mind. There is a simple reason behind this, penguins are often seen while standing or walking on snow and this can give an illusion that they don’t have knees.
But nothing can be further from the truth, penguins actually do have knees! The only difference is that the knees are hidden behind a layer of feathers and fur that helps the penguins to keep warm while swimming in cold water or while standing on land.
