The bobtail squid is no bigger than a walnut and is a tasty mouthful for predators in the coastal waters of Hawaii. However, the species continues to thrive in these waters in part because of its symbiotic relationship with a bioluminescent bacteria, which renders the squid virtually invisible to predators. Part of the "I Contain Multitudes" series.

The blackspotted puffer fish lives in the Pacific and Indian Oceans. To scare away predators, it puffs its body up like a balloon. However, this fish is poisonous, so it's not safe to eat. Now, that's one weird animal. Part of the "Weird Animal" series.
This episode focuses on the adaptations of arachnids and insects. Spiders inhabit backyards that design and build intricate silk webs. They have also developed numerous adaptations that make them efficient predators. Backyards also have insects living above and below the water's surface. More amazing adaptations are introduced including incomplete metamorphosis, eye development, and remarkable breathing apparatus. Part of the "Backyard Bugs & Other Arthropods" series.
Yellowstone National Park is a world of predators, scavengers and opportunists. In this vast and complex kingdom, two dominant predators reign supreme: the grizzly bear and the wolf. Size and power square off against speed and teamwork, as mighty grizzly bears contend with powerful packs of wolves for control of the food supply. As these two fierce competitors test their strategies for survival against each other, an entire food chain of scavengers survive in their wake.
The rock pocket mouse is a living example of Darwin’s process of natural selection. Not only is evolution happening right now everywhere around us, but adaptive changes can occur in a population with remarkable speed. This speed is essential if you’re a desert mouse living in an environment where a volcanic eruption can reverse selective pressure in nearly an instant. The film features Dr. Michael Nachman, whose work in the field and in the lab has quantified the selective pressure of predators and identified the genes involved in adaptation. In a complete story, from ecosystem to molecules, pocket mice show us how random changes in the genome can take many paths to the same adaptation—a colored coat that hides them from predators.

These hyaenodonts gave the world some of its largest terrestrial, carnivorous mammals ever known. While these behemoths were the apex predators of their time, they were no match for a changing world. Part of the "Eons" series.
Venomous animals have evolved a variety of mechanisms that deliver toxins to would-be predators and prey. Curator Mark Siddall discusses some of the anatomical features these venomous animals have adapted.
Part of "The Living Oceans" series. Captures the lives of predators and prey in the world's oceans. Explores the hunting habits and defenses in the populations of several species.
Drawn by a dense population of the largest bears in the world, wildlife expert Casey Anderson flies to Kodiak Island, Alaska. He wants to see firsthand how these predators hunt and compete during the annual salmon run. Part of the "Expedition Wild" series.
Marine biologist Chelsea Bennice discusses the amazing superpowers of the octopus. These sea creatures have incredible abilities and adaptations. They use camouflage, mimicry, and jet-power to outwit their predators. They also have the ability to learn new tricks to solve problems.
In this episode, host Emily Graslie discusses the pangolin or "scaly anteater." They are typically found in Africa and covered in an armor to protect them from predators. Part of "The Brain Scoop" series.
Students learn about plant structures and how certain adaptations help them survive. After learning about plant defense mechanisms, students make predictions about what might happen when one touches a sensitive plant with a feather or a finger. Part of the "You at the Zoo" series.
Predators play a fundamental role in maintaining the health of ecosystems. Research strongly supports the contributions of wolves in particular to the functioning and stability of the overall landscape. Students will learn about conservation methods to reintroduce and protect wolves in the wild. Part of the "Saving a Species" series.
Part of "The Living Oceans" series. Captures the mysteries of venomous marine creatures, such as nudibranchs, sea anemones, jellyfish, moray eels, and scorpionfish. Although these creatures can be fearsome predators, their defensive behaviors are also illustrated to highlight the predator/prey relationship that is a fact of life in marine environments.
Wildlife expert Casey Anderson takes on the task of tracking and filming one of North America’s most elusive predators, the mountain lion. He and his hounds set out to track a mountain lion hoping to study its anatomy and leaping ability. Part of the "Expedition Wild" series.
Nutria, an alien species in Louisiana, is having devastating effects on native wildlife. They are native to South America and have no known natural predators in the wetlands of Louisiana. Zoologist Nick Baker goes to investigate the damage to plant life from these voracious vegetarians. Segment of video from Wild Chronicles Series.
On the Galapagos, there is a lizard that is at home in the sea and sand. These marine iguanas have learned to adapted to the changing environment of the islands, but they also have to learn to escape different predators whether on land or in the water. Segment of video from Wild Chronicles Series.
Dr. Kimbro and Dr. Hughes devise an experiment to measure how well juvenile oysters (spat) fare at various test sites. They hope to better understand how predators and environmental factors affect the spat’s chances of survival. Part of the series "In The Grass, On The Reef."
Bioluminescence is a chemical process that allows living things to produce light. On land, fireflies are one of the most visible users of bioluminescence. In the ocean, bioluminescent creatures can be found from the surface all the way down to the deep sea floor. Scientists are still trying to figure out why and how animals adapted this feature.
