California is seeing a surge of sea otter pup births.
"It's an unbelievable opportunity to see a species recover the way the sea otters have... and to see them in such abundance," said Joe Mancino of the Elk Horn Slough Safari.
The southern sea otter is beginning to thrive thanks to preservation efforts.
In the Elkhorn Slough located in Monterey County, there are 18 new pups.
Experts say over a century ago, there were only 30 to 50 otters in existence.
Now there's nearly 3,000 southern sea otters on the Central California Coast.
