By definition, an invertibrate is an animal without a backbone, such as a worm or jellyfish. So the Nyala Antelope is most certainly NOT an invertibrate.
A worm can live underground even though it is an animal. The reason for this is because all of the oxygen,, food and moisture it needs is in the soil. And a worm is also an invertibrate.
