Life forms on the Antarctic continent are sparse because of the severe climate. Nevertheless, biologists have found bacteria and yeast growing just 183 miles from the South Pole. A lichen was found in a sunny canyon 210 miles from the Pole, and a blue-green alga was observed in a frozen pond 224 miles from the Pole. Microbes related to lichens colonize in green and brown layers just beneath the surface of rocks facing the Sun. Mosses and liverworts grow in some ice-free areas along the coast. Two species of flowering plants a grass and an herb grow along the Antarctic Peninsula.

The native land animals are limited to arthropods (insects and the like), of which 76 species have been discovered. Nearly all of these species are found only in Antarctica. These springtails, midges and mites generally live along the coast among plant colonies. The southernmost known animal, a mite, has been found 315 miles from the South Pole.
