Pelagic Red Crabs and Ocean Patterns

The video explores the phenomenon of pelagic red crabs washing up on California beaches, linking their movements to ocean and climate patterns like El Niño and marine heatwaves. These crabs, though not true crabs but squat lobsters, serve as indicators of oceanic changes. Studies show their distribution is affected by upwelling and climate events, highlighting the impact of climate change on marine life. The video emphasizes the importance of understanding these changes for future conservation efforts.
