Silently suspended in water, with only their eyes, nostrils and ears breaking the surface, these members of the crocodilian family play a terrifying sit-and-wait game with their prey, striking with lightning speed, chilling accuracy and a deadly bite stronger than any other living creature. Their victims stand little chance once held in their strong jaws. Land-dwelling prey are equally at risk--crocodilians can walk, gallop and leap at high speed, making them among nature's fiercest predators.

The ancestors of the elephant once roamed across much of the planet, but today, only two species survive: the African elephant and the Asian elephant. In this colorful introduction, young readers learn about the physical attributes and life history of the largest land mammal on Earth. With a massive body and huge ears that serve as built-in air-conditioning, a six-foot-long trunk with "fingers" that help it forage for food and water, tough, protective skin and outsized tusks used as tools and weapons, the elephant is a force to be reckoned with.
Just as fascinating is the...

There's no greater thrill than spotting one of these tiny birds in the garden, and young readers will be fascinated by how this avian machine works. Hummingbirds are the smallest birds in the world, but they exploit every advantage that comes with their modest size. Exploring the World of Hummingbirds is a fully illustrated introduction to the hummingbird's high-performance lifestyle.
Built for efficiency and fueled with high-energy nectar, this bird runs at a high temperature during the daytime, its heart beating 650 beats a minute, and its dense feathers keep it warm at...

With sturdy, streamlined bodies, outfitted with insulating blubber, flippers, tail flukes and fins, whales -- all known as cetaceans -- are built for life in the water. In Exploring the World of Whales, we meet the baleen whales and the largest members of the toothed whales, including the killer whale, the biggest of the dolphins. These marine mammals range in size from the 108-foot-long (33 m) blue whale to the barely 9-foot-long (2.7 m) dwarf sperm whale while boasting a range of distinctive physical traits, including the sperm whale's gigantic head, the humpback's...
