Centuries ago, when penguins were first encountered by European explorers, they were not thought to be birds but rather a fish-like relative. Subsequent accumulation of knowledge has shown penguins to be an avian species with unrivaled aquatic attributes, owing to a number of evolutionary adaptations: shape change, low drag, ability to regulate buoyancy, and extraordinary surface compliancy from their featheration. They are indeed the most extremely specialized diving bird, having given up flight (which otherwise is hugely advantageous) to the benefit of underwater prowess (such as speed, maneuverability and an ability to exploit an extraordinary range of depths). This flightlessness, however, also comes with costs that are substantial for a seabird (such as the inability to cover large distances quickly in reaction to ephemeral prey); and the energy needed to cope with moving through an aqueous environment, which is more resistant than air. For penguins, the high energetic costs in exploiting the ocean environment thus makes them especially sensitive to changes in food availability or their access to their prey. While a number of “penguin books” cover the natural history, mainly of breeding aspects, few address in much detail the incredible aquatic nature of these creatures. A huge amount of information has been amassed over recent past decades thanks to dramatic advances in microelectronics, bio-logging and maturation of some long-term studies of penguin life history. This work represents an integration of all these data with charts, maps and graphs, along with richly illustrated photos by experts in the field.

When Edward and Annie wake up one day, something is different. What could it be? Join this penguin pair on an adventure through the marine world exploring the unknown parts of their aquarium home. As they meet the other wonderfully strange creatures living there, these penguin friends discover that the world is much bigger and more interesting than they ever knew. Will they learn that different is not too bad, especially when you're safe among your friends? Edward and Annie teaches 4 to 8-year-olds that the best adventures start with trying something new a community is made of individuals who are each different, beautiful, and amazing trying new things can be rewarding In this funny read-aloud picture book by Caryn Rivadeneira, children will meet the real-life rockhopper penguins, Edward and Annie, who made a big splash on social media learn about the other sea animals that live at the aquarium, including Wellington the penguin and Annik the baby beluga learn fascinating science facts during family reading time or preschool and elementary STEM lessons in marine biology laugh at the penguins' curious questions and silly antics Your family will fall in love with these sweet, energetic penguins as together you discover that the world is a wonderful and surprising place—a place that is even better when explored with a friend by your side!

Explains how penguins use their flippers and fins and tells how they live in their underwater world.

Examines every major aquatic organism as well as lesser-known and rare life-forms including water-dwelling plants and animals and the algae and bacteria that constitute the first links in the food chain.

Discusses the nesting habits, diet, family and social lives of penguins, and the current threats to their habitats.

Journey south of the equator to the cold-water currents of South America, Africa, Australia, and Antarctica, where seventeen different types of penguins reside. An early explorer wrote, “We came across a multitude of strange birds. They could not fly, but ran quickly enough to get away from us…. Nature appears to have endowed them with great agility: they are wonderful swimmers.” In The World of Penguins, critically acclaimed biologist and wildlife educator Evelyne Daigle, brings readers an in-depth view into the fascinating environment of these exquisite birds. The riveting text coupled with detailed illustrations by well-known, wildlife illustrator Daniel Grenier, will capture readers everywhere as they take “flight” into the land and underwater world of penguins.
