An electric eel can generate enough current to stun its prey. Johns Hopkins University neuroethologist Eric Fortune traveled to Ecuador to study electric knifefish in their native habitat. Back at Johns Hopkins University, research collaborator mechanical engineer Noah Cowan and the rest of the team use Fortune's field data to help with their observations and experiments in the lab. With support from the National Science Foundation, they are studying the knifefish to learn more about how the brains of animals work to control their behavior.

Part of "Show Me Science" series. Are animals intelligent? Bees communicate with each other. Monkeys use rocks and sticks to help them get food. Is this instinctual or is it evidence of thought? Some scientists believe that one measure of intelligence is self-awareness, and that an animal's reaction to its own image in a mirror can tell us whether or not it is self-aware. Looks at fish, birds, monkeys, and primates and their reactions to themselves in a mirror. Researchers look for signs of self-recognition as they observe, record, and interpret the reactions of these animals. Includes suggestions for careers in this field of study.
How do biologists answer questions and solve problems? Within the context of answering this question, data collection, recording, and analysis are overviewed. Examines two animal behaviors: feeding and communication. Illustrates the different behaviors of lions, alligators, and chimpanzees, and then highlights the "waggle dance" used by bees. Supports the learning of these concepts in tandem with the textbooks also offered by the publisher.
Scientists and conservationists use the latest technologies as they work to preserve and protect over 5,000 endangered animals. Some techniques include communication with animals, raising orphans, moving animals to new areas, and mating programs in zoos. Uses a Q and A format.
The octopus is a master of stealth and disguise. Scientists have set up several obstacles and mazes for octopi to travel through in an attempt to study their anatomy. Segment of video from Wild Chronicles Series.
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.
Tessa, a brown capuchin monkey, joins the Jungle Friends Primate Sanctuary in Florida. She has been diagnosed with diabetes, and her owners are no longer able to care for her. At the sanctuary, Tessa learns to make new friends and follow a strict diet. Segment of video from Wild Chronicles Series.
Looks at amazing instincts of three kinds of mammals: whales, bears and monkeys (primates). Segment 1, Marine Migration: Follows the humpback whales' migration through the waters between Maui and Alaska. Describes "bubblenetting", the whale's unique feeding behavior. Segment 2, Hibernation and Homing: Shows how bears' hibernation and homing instincts help them survive treacherous conditions. Segment 3, Parenting Primates: Visits the island of Borneo and shows how adult proboscis monkeys, macaques, and orangutans teach their young. Suggested classroom activities follow each segment.
Across the animal kingdom, some of the most essential lessons-and the most extreme challenges-occur in the first moments of life. From ostrich to orangutan, egg sac to live birth, infanticide to matricide, the diversity of behaviors between parent and progeny is as great as the diversity of life on our planet. Academy Award-winner F. Murray Abraham narrates.
The answers to the age-old question 'What do women want?" just might be found in the animal kingdom. Scientists using unorthodox techniques and the latest technology are probing the mysteries of attraction. Discover how females are shaping the future of their species by choosing the best mates.
This video outlines the complementary nature between structure and function. Students will observe specific animals that have structures geared towards a particular function. Topics covered include the structures and processes animals use involved in breathing, eating, passing waste, and moving. Part of the "Biology" series.
The Druid clan, so-named by scientific researchers, had been one of the largest and most powerful packs of wolves ever studied. When their dominant alpha leaders are killed, their reign over Yellowstone National Park's Lamar Valley comes to a sudden end. But a lone male, who has been courting some of the female juveniles, joins the defeated remnant of the Druids and helps them battle to recover their land.
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.
Explores the open savannahs of Africa, particularly the mammals that inhabit them and the trees that border the grasslands. Shows how the different animals interact with each other and the non-living elements of their habitat to maintain a healthy balance. Also investigates the threat from an increasing human population for homes, food, other resources, and the resultant threat to the survival of many animal groups. Looks at international breeding programs around the world, which were established to protect these animals and enable them to reproduce in captivity, so their gene pool is preserved.
Most pet owners talk to their animals at one time or another, and some do every day. But, how much do pets actually understand? Is their perception anything like our own? These are the questions that fascinate Irene Pepperberg and she’s looking for answers from the animals themselves, specifically – African Grey Parrots. The Harvard psychology professor is a bit like the character Dr. Doolittle because she’s been talking to parrots for decades. With help from the National Science Foundation, she’s researching how much the birds understand about shapes, numbers, and colors. Her next phase of research involves how the parrots detect optical illusions, and whether they perceive them the way humans do. Her research will also reveal more about how a bird’s vision works.
Neuroscientist Cindy Moss is investigating how animals use sensory information to guide their behavior. Her team at Johns Hopkins University's "Batlab" is currently focused on bat echolocation. The group aims to better understand how these highly specialized creatures perceive and navigate their world. Part of the "Science Nation" series.
Do animals change their behavior when humans hike through the forest or move next door? Scientists looking to answer this question are relying on webcams. They are hoping to gather data to pinpoint adaptations in animal behavior related to human interaction.
What’s on the menu? Find out how aquarists feed some of the largest and smallest aquarium animals under their care. Understanding marine food webs, animal behavior, and nutrition are important skills needed for this science-based career. Part of the "Aquarist" series.
Juncos, also known as snowbirds, are readily observed in backyards, city parks, and forests. These little gray birds are so common they can be easily overlooked. But for scientists who study animal behavior, ecology, and evolutionary biology, the junco is a rock star. Part of Ordinary Extraordinary Junco (Intro).
