There otter be a law.
All sea otters in California sea otters are the descendants of a single colony of about 50 sea otters located near Bixby Creek Bridge in March 1938 by Howard G. Sharpe. The recovery is remarkable. From those 50, there are now about 2,650 sea otters in California. But the news is not all good; the sea otter’s population plunged 25% from 2016 to 2017. The primary culprit appears to be a cyanobacteria, Microcystis, that produces a toxin called microcystin. Agricultural runoff is the cause of the algae blooms. For example, in Elkhorn Slough, the mountainous cattle manure from Moonglow Dairy runs into the Slough in heavy rainstorms. Moonglow is hardly the only offender; it’s not even the only offender in Elkhart Slough.
Shark attacks appear to have also played a role. So the California population of sea otters remains an endangered species.
Even if you wouldn’t think it to look at the otters in Elkhorn Sough.
