Antarctica is the only continent without a native species of ants. This harsh, frigid environment presents extreme challenges for most insects due to the cold temperatures and lack of available food sources. While some species of ants can adapt to various environments, the severe conditions of Antarctica inhibit the survival and establishment of ant populations. The continent's ecosystem is primarily composed of marine life, such as seals, penguins, and various types of birds, along with specialized microorganisms that can withstand the extreme cold. This absence of ants is an interesting ecological characteristic of Antarctica's unique and isolated environment.
