The National Oceanic and Atmospheric Administration (NOAA) found an estimated 35,000 Pacific walruses crowded together on the shore in northwest Alaska.

It's the largest gathering of Pacific walruses ever recorded, and scientists say the reason the walruses have come on shore is because melting sea ice has left them with no other options for refuge.
