What is the disadvantage os using common names for species?
A disadvantage is the lack of clarity on what organism you're actually talking about. For example, if you write something or other about a badger, it doesn't follow that I'm going to automatically know which particular badger you're referring to. A number of species of badger exist.





It can also lead to muddled tranlations. There's a bird known in French as a pingouin. It's a semi-aquatic hunter of fish, a good swimmer and can be found in very cold parts of the world with plenty of ice and snow. Just looking at the French word might be enough to make it obvious which bird's under discussion. As it happens, the obvious answer would be wrong. It refers to an auk, not a penguin. I've got a German wildlife map which was translated from French, and precisely that mistake leaves it talking about penguins in the Arctic.
Reply:Many animals have the same common names in different countries or the common names vary from place to place, making it non-universal.
