Episode 202: Sentinels of the Seas

Bottlenose dolphins are a beloved Florida icon. But recent studies show disturbing signs of immune system dysfunction and disease plaguing this charismatic mammal. These problems might be linked to legacy contaminants and other pollutants which bio-accumulate up the ocean food chain. For decades, toxic chemicals have made their way into the oceans, leaving fish and marine mammals vulnerable.

As sentinels of ecosystem health, dolphins potentially hold clues to environmental hazards that could impact humans. Changing Seas visits the world’s longest running dolphin research program and other marine mammal centers for a better understanding of the silent threats lurking beneath the waves.
