Zealandia, sometimes referred to as the "eighth continent," is a large submerged landmass in the southwest Pacific Ocean that is almost entirely underwater. It is believed to have been a part of the supercontinent Gondwana, which broke up millions of years ago. Zealandia includes New Zealand's North and South Islands, as well as the country's surrounding submerged continental shelf.

The debate over Zealandia's status as a continent highlights the complexity of defining continents and the fact that the concept of a continent can be somewhat subjective. However, it is not officially recognized as the eighth continent, and the traditional seven-continent model continues to be widely accepted.
