Some Archaea thrive in extreme places such as in thermal pools, hot vents at the bottom of the sea, extremely salty water, and even in underground oil reserves. This book examines the diverse Archaea kingdom and the division of these organisms by their unusual biology into three main groups. It also explains why little in general is known about them, and why further classification of Archaea is so difficult.
How in the world do you classify the more than one million species in the animal kingdom? This fact-packed book divides animals into the major phyla, classes, and critical features.

Margarita necesita un hogar que sea ideal. Ella le pide a Viento que le ayude a encontrar el hábitat perfecto para echar sus raíces y él acepta el reto.
