These plants grow close to the ground where the temperatures are the warmest. Plants are only able to grow in the tundra for less than 3 months each year. Even during the short summers the ground only thaws about a meter below the surface. Only a few trees grow in the tundra biome. If any trees do grow they are only about knee high because of the short growing season.
Penguins are warm blooded.
They are birds that can not fly, but they are very good at swimming. On land, penguins waddle and hop much diferently than any other bird. In the water though, they are swift and graceful. There are at least 17 different species of penguins, but they are not all found in Antarctica. Some species are found in the subantarctic.
