This has led to the incredible speed of the cheetah, the fangs of the king cobra, and even bacteria that lives near the hottest vents on Earth! This volume highlights some of the most extreme examples of living things surviving, from long distance migration to supersenses. A colorful, vibrant design accompanies main content that support life science and biology curricula. Graphic organizers aid comprehension and provide interesting facts and stats.
