All animal species undergo a process of constant change. Those that survive do so because they perfect certain strategies that enable them to develop successfully in their environment. Discovers that conditions in the environment determine which abilities animals develop, and introduces survival strategies such as camouflage, poison, symbiosis, parasitism, and adaptation. NOTE: Contains nudity.

The hummingbird has a forked tongue that is lined with hair-like extensions. Its design is especially useful for drinking nectar from flowers.
New research finds that hummingbird species living at high altitudes have evolved hemoglobin with enhanced oxygen-binding properties so they can thrive in oxygen-poor environments. A team of scientists demonstrate how hummingbirds adapt to life at high altitudes.
An alien species has found its way to an island off the coast of Texas. Wildlife experts believe that arrived after a flood, and they are wreaking havoc on the natural wildlife. They seem impossible to combat, and researchers are beginning to study them because of their tenacity and survival skills. Segment of video from Wild Chronicles Series.
How can honeybees communicate the locations of new food sources? Austrian biologist, Karl Von Frisch, devised an experiment to find out. By pairing the direction of the sun with the flow of gravity, honeybees are able to explain the distant locations of food by dancing. The scientists at Georgia Tech University explain the design of Von Frisch's famous experiment and describe the precise grammar of the honeybees dance language with new computer vision techniques. They hope the research into behaviors of social insects will aid in the design of better systems of autonomous robots.
After Charles Darwin first visited the island archipelago of Galapagos in 1839, it took him another twenty years to decipher that the scene he'd witnessed was the most perfectly preserved biodiversity on the planet. His theory of evolution, published 150 years ago, pulled back the curtain on a debate that had been simmering for years, and still percolates. Today Darwin would be surprised by the tourist mecca Galapagos has become--200,000 visitors a year, 40,000 permanent residents. The impact on the most unique collection of endemic wildlife in the world has been heavy. Too many people are bringing too many of their ways (and invasive species) from the outside world that are threatening the future of this one-of-a-kind place. What would Darwin think of how Galapagos has evolved in the twenty-first century?
Host Dylan Dreyer journeys through the ultimate story of survival on the Alaskan frontier. She witnesses unspoiled landscapes and the raw power of nature as animals and people fight to survive. Part of the "Journey With Dylan Dreyer" series.
Part of "The Living Oceans" series. Reveals the hunting habits of the ocean's deadliest predators: sharks. Captures the mating habits of hammerhead sharks and the hunting habits of blue sharks, six-gilled sharks, sand-tiger sharks, and white-tipped reef sharks. Explores the great white shark hunting seals and sea lions near the Farrallon Islands, explaining that the bloodthirsty animal culls out animals that are weak or ill.
A rip current is a narrow, fast-moving channel of water that starts near the beach and extends offshore through the line of breaking waves. If a swimmer gets caught in a rip current, the best thing they can do is stay calm. The current will not pull a swimmer underwater, but it will pull them away from shore. A swimmer caught in a rip current should float and wave for help. Do not try to swim back to shore or against the rip current. Part of the "Danger Zone" series.
Films the landforms and plant and animal life of Death Valley. Details how animals and plants have adapted to this extreme environment. Interviews biologist who are studying the endangered desert pupfish that resides in the aquifer known as Devil's Hole. Studies the desert tortoise and its remarkable adaptations to this desert biome.
The United States Geological Survey (USGS) conducts research on the desert tortoise in the Mojave Desert with the hopes of allowing the species to recover and escape the threat of extinction.
Students meet the world's fastest cheetah, Sarah. They also learn how cheetahs have adapted to survive in their savanna habitat. Then, they make predictions about how fast cheetahs can run. Part of the "You at the Zoo" series.
Many outlet glaciers in Greenland feed ice from the land into fjords, where discharge of icebergs and melting of the glaciers by warmer ocean waters contribute to rising sea levels. David Holland of NYU studies what happens in the fjord when ice meets water. He also studies how the dynamics at the margin between ice and sea are changing, and what those changes could mean in the future for global sea level rise. Part of the National Science Foundation Series “Science Nation.”
Focuses on animal life in four extremely inhospitable deserts: the Namib's adaptive elephant, a dromedary roundup in Australia's outback, fish in thermal lakes in Mexico's Chihuahua desert, and the Sahara's Ennedi crocodiles. Survival is an eternal challenge to any life in these places.
Go behind the scenes with Angelina and investigate the equipment and engineering skills needed to recreate ocean habitats. Explore a typical workspace of an aquarium and get a feel for the everyday problem solving skills needed as an aquarist. Part of the "Aquarist" series.
Explores the world of butterflies and bees. Segment 1, The Lives of Butterflies and Moths. Describes the four stages of the life cycle of the butterfly and moth: egg, larva (caterpillar), pupa, and adult butterfly or moth. Shows how their diet and defense systems are necessary for survival. Segment 2, Bees and Plants. Explains pollination and why plants depend on bees for survival. Suggested classroom activities follow each segment.
Follows scientists as they explore the mysteries of attraction, natural selection, and survival of the fittest in the male animal kingdom. The scientists use unorthodox techniques and the latest technology to study how males in the animal kingdom achieve their main goal of passing their genes to the next generation. For some species in the animal kingdom, males will go to extremes to win a mate. They make music, fight, overdress, and even agree to be eaten alive to ensure survival of the fittest.
Discusses how animals use their teeth and horns for protection and survival. From the Kool Books series narrated by Hector Bonilla.
Characteristics enabling organisms to survive and reproduce are referred to as adaptations. This program explores the wide range of adaptations that all living things exhibit. Important terminology includes environment, characteristics, competition, survival, structural adaptations, and behavioral adaptations.
