Most of the Arctic consists of sea ice and not land. Much of the land that is found in the region is tundra coverd with permafrost. Only a few inches of this permafrost thaws during the short summer months. The desert, especially the hot desert, has a greater variety of plants and animals, does not have permafrost (except Antarctica) and all deserts are located on solid ground, not sea ice.
Arctic animals have thick covering to protect them from the cold . Desert animals have a thin covering of skin to get coldness.
