Part of "The Living Oceans" series. Captures the ecological balance established between animals and plants on a Caribbean coral reef. Details the symbiotic and commensally symbiotic relationships along with the predator/prey relationship.

Staghorn and elkhorn coral have become threatened species. These corals are the building blocks of reefs in the Caribbean and Florida Keys. Part of the "Coral Comeback" series.
Describes how coral reefs form and their importance to the sea life they sustain. Gives characteristics of hard and soft coral and shows examples, pointing out that both grow extremely slowly. Locates major coral reefs on a map and restates reefs' contributions to humans. Names several different threats that could destroy these wonderful phenomena.
Home to 25% of all marine species, coral reefs protect the coastlines of more than 100 countries and provide 500 million people with jobs. However, reefs are experiencing damage due to climate change, ocean acidification, and other pressures. Mote Tropical Research Lab and the Coral Restoration Foundation, both in the Florida Keys, are performing groundbreaking work by accelerating coral growth in the lab, creating nurseries in the ocean, and replanting on damaged reefs. Their efforts create hope for the future of sustainable coral reefs around the globe.
Societal change and growth is impacting the ocean ecosystem. One of these consequences is the rapid decline and death of coral reefs. Part of the "Coral Comeback" series.
Symone Johnson, educator at National Aquarium, provides an overview of the series "Coral Comeback." She outlines coral reefs and discusses their importance to healthy ocean ecosystems. Part of the "Coral Comeback" series.
Learn about some of the bold and brilliant ideas researchers and conservationists have to rescue corals and coral reefs from disaster. Part of the "Coral Comeback" series.
Coral reefs are particularly sensitive to ocean acidification, which has decreased their ability to form skeletons. Ocean acidification is also causing reefs to crumble and disappear. Part of the "Coral Comeback" series.
Coral reefs are some of the most precious habitats in the ocean, which has earned them the nickname "rainforests of the sea." They're a complicated ecosystem where thousands of species are supported by some of the smallest life-forms. Part of the "Coral Comeback" series.
The American South is home to some of the world’s most spectacular ecosystems, from coral reefs to salt water marshes. These two national monuments are underwater paradises and support a diverse and complex system of plant and animal life.
Can damage to coral reefs be repaired? Two researchers are looking for solutions to this question. Dr. Steve Palumbi conducts research on the corals around Ofu Island in American Samoa. He is trying to determine why these native corals can withstand ocean temperatures that, in other coral species, would lead to coral bleaching. Along with graduate student Megan Morikawa, Palumbi is testing whether these heat-resistant corals can be transplanted to reefs that have been damaged or destroyed.
Corals are important ecosystem engineers, providing habitat and nutrient recycling to tropical reefs. However, coral species’ richness and abundance are in decline worldwide, due in large part to the impacts from global industrialization and human population growth. Coral disease is a major contributor to this decline of tropical reefs, and therefore, investigations into the causes of and remedies to these diseases are of critical importance. Part of the National Science Foundation Series “Science Nation.”
This animation zooms into a coral reef to explore the tiny animals that build reefs, the photosynthetic algae inside their cells, and the damaging process of coral bleaching. Corals get much of their energy from symbiotic algae that live inside their cells. When ocean temperatures rise beyond a certain threshold, the algae’s photosynthetic machinery may be damaged and produce harmful reactive oxygen molecules. This animation shows how corals subsequently eject their algae in a process called coral bleaching, which causes the corals to turn white and often eventually die.
In this episode, scientists try to uncover what makes 25 percent of individual corals tolerant of warmer water. Can these "super corals" be strategically planted to help reefs withstand climate change? Part of the "Super Corals" series.
During a visit to Thailand, Jeff explores the underwater worlds of the Gulf of Thailand and the Andaman Sea. He also pays a visit to conservationists from Eco Koh Tao who are fighting to restore endangered coral reefs and giant clams. Part of the "Ocean Mysteries" series.
The scientific team visits the Chagos Archipelago, a tropical paradise with some of the healthiest coral reefs on the planet. They want to study reefs seemingly untouched by man but instead become witnesses to a bleaching incident that transforms the reefs right before their eyes. Part of the "Global Reef Expedition" series.
Hidden just beneath the waves of the Caribbean Sea lies a treasure trove of sea creatures in a fantastic underwater world. Circling the intricate coral reefs are creatures great and small. Wild Chronicles gets up close and personal with the denizens that call these waters home. Segment of video from Wild Chronicles Series.
This episode highlights recent studies related to beaches and marine life. Researchers have found that seagrass has a strong potential for curbing erosion. Other features include the impact of climate change on right whale movement, expanding efforts to save coral reefs, and the dangers of hurricane storm surge. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
Currents in the Pacific Ocean have brought derelict fishing nets and gear to the waters around the Hawaiian islands. These nets are a safety hazard to ships and cause extensive damage to the ecosystem by snagging on coral reefs, entangling wildlife, and polluting shorelines. Instead of adding these nets to already congested landfills, Hawaii’s multi-partner marine debris group came up with a unique program to downcycle this marine debris into usable electricity.
Lurking in the waters of the Atlantic Ocean is an unwelcome predator. The lionfish is an invader, and it is far from its home on coral reefs in the Indo-Pacific basin. The mystery of how they got here has slowly unraveled. A showy species for personal aquariums, they were likely dumped off the Florida coast when no longer wanted. Several small releases of lionfish have led to a population explosion that has increased 1,000 percent in less than 5 years.
