Sea otters are helping to control invasive crab species along West Coast, study finds

Researchers have observed a significant decline in green crab populations in areas with high sea otter populations, suggesting that otters could play a crucial role in controlling this invasive species.

Estuary ecologist Rikke Jeppesen noted, 'Given that the population size is about 100 and 120 currently in Elkhorn Slough, they can probably eat somewhere between 50,000 and 120,000 green crabs per year.'
