What do wild animals do when we're not around? Find out with National Geographic's Crittercam. Safely worn by wildlife, Crittercams capture video, sound, and other information, giving students rare views of the private lives of animals. Crittercams help to solve scientific mysteries by providing an animal's eye view. And what scientists learn from Crittercams helps them protect the very animals that wear them. Crittercam reveals crucial evidence that could solve the Northwest Hawaiian Islands' mysterious monk seal deaths.

In this episode, scientists study the hunting practices of leopard seals.
Greece's Sporades Islands are home to Mediterranean monk seals, one of the most critically endangered species on Earth. When a pup washes ashore in a storm, a group of dedicated scientists spring into action to nurse the seal back to health. Healthy and strong, the growing seal is released back into the wild with a GIS transmitter to track her adaptation. Segment of video from Wild Chronicles Series.
Researchers from NOAA's National Marine Mammal Lab track the migrating fur seals to understand where they feed in winter months and what marine resources they depend on for survival. It's early November and the team affixes a satellite transmitter to an adult female. They won't see her back on the Pribilof Islands until next July, and they hope the tag will stay on throughout winter and spring. Back at their offices in Seattle, the researchers begin tracking tagged animals via satellites.
The gray seal population in the Northeast has risen due to protection policies enacted by the federal government. Due to the population increase, conservation biologists are conducting experiments by placing tracking devices on the seals. They are analyzing their diving history, travel patterns, and foraging habits.
A mysterious killer is lurking in the steely waters off the east coast of Canada. Scientists are baffled by all the corpses on the beach. The seals bear bizarre spiral wounds which have led to one theory that one of the most elusive of all sharks is responsible, the Greenland shark. Scientists from the Canadian Shark Research Laboratory and the Apex Predator Program in the United States will try to solve the puzzle of the dead seals once and for all. Please note: this title shows images of animal corpses and shark attacks on seals.
In this behind-the-scenes glimpse into cataloging at The Field Museum, host Emily Graslie learns how to number small skeletal samples in the mammal collection. She also visits the seal fossil collection and examines the differences between the teeth of various species. Part of "The Brain Scoop" series.
Host Alex Dainis highlights the uses and history of parafilm. It is commonly used in health care, pharmaceutical, and research laboratories for covering or sealing vessels such as flasks, cuvettes, test tubes, beakers, Petri dishes, and more. Scientists and researchers use it in the lab since it is ductile, malleable, nontoxic, and self-sealing.
Professional remodeler Danny Lipford offers practical home improvement information to homeowners. Discusses products and ideas for saving money on energy bills: caulking, expandable foam sealant, weather stripping, thresholds, insulated socket sealers, attic and window insulation, water heater blankets, and compact fluorescent light bulbs. Looks at using a flexible wheelbarrow screen for sifting rocks from soil. Talks about Dremel cordless tools. Gives reasons why homeowners should use mulch.
Documentary records Project Puffin, the successful effort to repopulate Seal Island, Maine, with Atlantic puffins and terns. Notes their life, behaviors, and mating during the summer before fall migration. Also remarks on the interdependence of terns and puffins. Biologists comment.
It’s a fight for survival in Hawaii as rescuers work tirelessly to help the endangered monk seal population to recover. Then, a great blue heron is in grave danger after a soda can becomes stuck around its beak. Part of the Sea Rescue series.
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.
Many endangered animals are protected under the U.S. Endangered Species Act. The Endangered Species Act of 1973 is one of the most effective conservation laws in the United States. Using science-based management plans, it has prevented the extinction of 99% of the species it protects. Part of the "Endangered Ocean" series.
Part of "The Living Oceans" series. Reveals the habits and behavior of night-spawning coral, manta rays, lobsters, white-tipped sharks, cuttlefish, Humboldt squid, and opalescent squid. Shows the mysteries of ocean ecology in the annual spawning of coral, the molting of lobsters, the feeding habits of sharks and cuttlefish, and the deadly attacks of squid. Captures the death of thousands of opalescent squid as they lay their eggs, and then die in vast numbers.
Students can take to the skies and celebrate National Aviation Day on August 19th. Inspire an interest in design, engineering, and exploration with this look back on aviation history. Part of the “All About the Holidays” series.
An exhausted pelican lands on a busy highway in Florida, and host Matt Gutman is there to assist with the rescue. Then, a rescue mission is launched to save a manatee that became ill after spending too long in frigid water. Part of the "Sea Rescue" series.
The creatures in this episode love the beach. Jack goes on a coastal adventure with African penguins, sea lions, marine iguanas, elephant seals, and sea turtles. Part of the "Jack Hanna's Wild Countdown" series.
Polar bears are living on borrowed time. They are the descendants of grizzlies, long ago evolved to live and hunt on the frozen ice of the Arctic, eating a specialized diet of seal meat. But the winters have become increasingly warmer, the ice is disappearing, and raising a family becomes a much more difficult proposition when hunting time is short and food is scarce. Academy Award-winner F. Murray Abraham narrates.
Consider the following: humans live twice as long as their ancient ancestors did even though their bodies contain different types of synthetic and sometimes toxic substances. This is an unpleasant part of life in the modern age. Explores the health impact, wide variety, and alarming ubiquity of manufactured chemicals. Shows how communities around the world, including Inuit seal hunters, Asian and African farmers, and residents of an industrial town in the United States address the pervasiveness of molecular compounds found in pesticides, plastics, and other products. The benefits of these chemicals are weighed against their dangers.
A community of sea lions annually visits an island in the Gulf of California, where the babies are born and must be taught to swim. Compares seals and sea lions. Details physical characteristics, diet, behaviors, and enemies. The only enemy this "grizzly bear of the sea" cannot fight is fishing boats.
