Do kiwi live in underground holes?

No, kiwi is categorized as a parasite plant (parasitus inhomnia plantus). And like most of parasite plants they need a decaying or live organisms to develop their seeds. During hot weather the kiwi tree which does not produce any fruits releases its spores, then nearby animals inhale these spores which travel down the esophagus (feeding tract) and start developing. Later on when the animal dies farmers cut it open and harvest kiwi.
