An alarming number of Guadalupe fur seals have died after stranding themselves along California's coast. As a result, the National Oceanic and Atmospheric Administration (NOAA) has declared an "Unusual Mortality Event" and is investigating why the marine animals are traveling so far from their natural habitats.
North Carolina, where seals were rarely seen years ago, now has a colony or two. New England and California seal colonies are both up in number.
These 19-inch, flightless birds, the only penguins in the Northern Hemisphere, just might be better off as a result of wind and ocean current shifts in the last 30 years, a researcher says.
