Witness the intricate and interconnected web of marine life across diverse ecosystems in this compelling documentary series. In a display of teamwork, several giant trevallies and mobula rays collaborate to feed on a shoal of anchovies, highlighting the cooperative strategies of ocean predators. At Everglades National Park, bottlenose dolphins exhibit remarkable intelligence by herding mullet into a ring of mud for efficient hunting.
In coral reefs, grey reef sharks engage in a cleaning symbiosis with cleaner wrasses during the day, while at night, they and whitetip reef sharks join forces to hunt within the vibrant coral ecosystem. However, rising sea temperatures threaten these reefs as corals lose their vital algae, endangering these crucial marine habitats.
California’s kelp forests benefit from the presence of sea otters and California sheephead, which help control sea urchin populations, maintaining ecosystem balance. Farther north, Steller sea lions and humpback whales converge to feast on breeding Pacific herring shoals, although the herring populations have been declining due to overfishing and unsustainable practices.
Meanwhile, the warming seas have led to a proliferation of compass jellyfish, impacting marine biodiversity. Off the coast of Chile, millions of seabirds find sanctuary, illustrating the importance of protected marine areas. In a positive conservation story, the Raja Ampat Islands have become a sanctuary where sharks, once depleted, now thrive, showcasing the potential for ecosystem recovery through conservation efforts.
