Every specimen has a story, and in this episode, host Emily Graslie highlights skates. For hundreds of years, sailors sold manipulated skate specimens to tourists and oddity collectors claiming they were aliens and demons. In reality, it's just a fish. Part of "The Brain Scoop" series.

Host Emily Graslie takes the fish fossils she found at Fossil Lake back to the museum. She works with Akiko Shinya, who is a fossil preparator, to prepare the fossils for exhibition. Part of "The Brain Scoop" series.
Diaphonization, otherwise known as clearing and staining, is one of the most photogenic preparation methods used by research scientists. It's beautiful, but is it practical? Host Emily Graslie interviews Dr. Caleb McMahan, Collection Manager of Fishes, on how he uses this technique to answer questions about the evolution of fish. Part of "The Brain Scoop" series.
Ancient primate progenitors had bodies a lot like those of modern monkeys and spent tens of millions of years living in trees. From them, humans inherited versatile hands, amazing vision, and capable brains. Part of the “Your Inner Fish” series.
A key moment in the evolutionary saga occurred 200 million years ago, when the ferocious reptile-like animals that roamed the Earth were in the process of evolving into shrew-like mammals. But these reptilian ancestors left their mark on many parts of the human body, including skin, teeth and ears. Part of the “Your Inner Fish” series.
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.
When Hanna helps herself to some water from the river, she finds it very polluted. The children and Suzie work their way upstream searching for clean water. During their journey, they learn about the effects of pollution on the environment. Part of the "My Little Planet" series.
Host Emily Graslie travels to Fossil Lake in Wyoming. In this episode, she learns the history of Fossil Lake from Lance Grande, who is the Negaunee Distinguished Service Curator at The Field Museum. Fossil Lake is home to the largest complete representation of early Eocene life in the world. Part of "The Brain Scoop" series.
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.
Did you know Oregon crab fishers lose their pots because they often encounter high winds and waves up to 40 feet? Join Joel on this adventurous quest as he boards a vessel to sail the Oregon coast in search of crab pots in an effort to help clean up the ocean. Part of the Curiosity Quest Series.
Scholar Johan Norberg travels to New Zealand to find out how the Quota Management System has helped save fish populations. Thirty years ago, New Zealand fisheries were on the brink of disaster due to overfishing. Today, commercial fishing off New Zealand provides fish for consumers worldwide, an excellent livelihood for fishers, and a stronger, healthier ocean and fish population.
After the end of the last ice age 10,000 years ago, populations of marine stickleback fish became stranded in freshwater lakes dotted throughout the Northern Hemisphere in places of natural beauty like Alaska and British Columbia. These little fish have adapted and thrive, living permanently in a freshwater environment drastically different than the ocean. Stickleback bodies have undergone a dramatic transformation, some populations completely losing long projecting body spines that defend them from large predators. Various scientists, including David Kingsley and Michael Bell, have studied living populations of threespine sticklebacks, identified key genes and genetic switches in the evolution of body transformation, and even documented the evolutionary change over thousands of years by studying a remarkable fossil record from the site of an ancient lake ten million years ago.
The ocean is full of various species of sharks and rays. In this episode, host Emily Graslie takes a look at some of the more unique examples of these fish. Part of "The Brain Scoop" series.
One of the fifteen parts of the "Farm to Market" series. People eat seafood caught from the ocean or raised on farms, which is called aquaculture. Highlights a variety of these foods, including salmon, catfish, mussels, and sea urchins. Shows how different seafood is grown, caught, and cultivated. Visits a Japanese fish market where unique sorts of seafood are bought and sold.
Goes in search of sustainable solutions. In the Canary Islands, fishermen use rod and line for a valuable species and only take fully mature fish. In Oman, the authorities will only allow fishermen to use one kind of boat and net, and they strictly monitor the catches. Leading decision-makers describe how drastic action must be taken to protect wild stocks and ecosystems, but almost nowhere are measures being taken that help alleviate the crisis. Part one of this series explores the state of global fisheries.
The Tennessee Aquarium in Chattanooga is a unique freshwater aquarium. Visitors learn how a river is formed, how fish live beneath its surface, and other fish facts. Showcases important world rivers and their fish. Introduces aquarium workers, food preparation, the quarantine area, and a control center. Notes the aquarium is a learning place from top to bottom.
Goliath groupers are the largest of the groupers in the Atlantic basin. They were once so overfished in the Southeastern United States, they were considered for listing under the Endangered Species Act. Thankfully, a dedicated group of marine scientists worked to prompt NOAA to ban all of their harvest. This action in the early 1990s gave the grouper time to recover and gave scientists time to learn more about this fish.
Figuring ways to clean up contaminated waters is a huge challenge. But luckily, a simple piece of plastic that mimics fish fat can help. Part of the "Science Out Loud" series.
Part of "The Living Oceans" series. Reveals the height and structure of undersea kelp forests inhabited by garibaldi, sea urchins, senorita fish, octopi, moray eels, and sea otters. Shows winter storms detaching kelp from their holdfasts to provide floating nurseries for another generation of fish and other marine animals.
In a response to the overfishing of Blue Fin Tuna, Japan began captive fish breeding programs. The University of Tokyo is trying to take these programs a step further. They have started a program to genetically alter mackerel to give birth to blue fin tuna.
