Answer: I contacted a zoo where they have a collection of penguins to confirm my thoughts on this question. The simple answer is yes, penguins do have jointed legs. Although you may not be able to see them, perhaps because of the folds of abdominal skin that penguins often have, they do have 'knee' joints. The way in which penguins walk is related to a number of factors. Their legs are relatively short and they are set far back on their bodies.

To our knowledge there are no studies concerning UV-B effects on penguins. As their eyes are exposed to a lot of UV due to the high reflectivity of snow and a marked enhancement during the ozone hole, investigation into the impact on penguins is desirable. The fact that penguins are visual predators, eating krill or fish in the water column, would make any eye damage an important issue for survival. See similar questions...

No. Penguins, like all other birds, do not have teeth. The chicks do have an egg tooth, but this is not a real tooth, but rather a sharp bump on the top surface of the bill which is used to break the egg when hatching. Penguins do have rearward-pointing, tooth-like barbs on the tongue and roof of the mouth. These are not used for chewing, but instead assist in the swallowing of their slippery prey.
