Deep Sea Ecosystem Knowledge Assessment

The video explores the diverse life forms in different ocean zones, highlighting the challenges of deep-sea exploration due to harsh conditions. It describes the continental shelf and neritic zone, where sunlight supports abundant marine life. The transition zone, with limited light, hosts unique creatures with adaptations like bioluminescence. The video emphasizes the ocean floor's varied topography and the complex food web starting with phytoplankton.
