The polar regions' cold invertebrates such as insects and spiders are usually small enough to be able to warm up Most species are found on or around the coasts, particularly on the Antarctic Peninsula; the northernmost part of Antarctica. Animals, especially krill, consume this abundant food supply, and multiply to astounding levels. Adult Antarctic krill are approximately 6 cm in length and weigh over 1 gm. Any animals on land or in the sea will feed from these two sources. loss through the flipper or fluke. They are usually single celled and use photosynthesis to make energy.
