Southern sea otters, among the furriest and most beloved critters in the animal kingdom, have declined in number for the second year in a row, according to scientists who are trying to pinpoint possible causes.

Once hunted to the brink of extinction and currently listed federally as a threatened species, the charismatic otters often seen frolicking off Central California have dwindled to just 2,711 animals.

That figure, based on counts made by the U.S. Geological Survey, represents a 3.6% drop from the 2009 estimate. More alarming, scientists say the number of otter pups has decreased by 11%.

Additionally, their geographic range -- about 200 miles from Pigeon Point to Gaviota State Park -- appears to be shrinking at both ends.
