Twice as long as humans are tall, the great white shark is the largest predatory fish in the ocean. This fish will go through 20,000 teeth over its lifetime. Read all about the fish made famous by the movie Jaws.
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.
