Welcome to my ice crevasse. Two divers meet an unexpected surprise in the frigid waters of Palmer Land on the Antarctica Peninsula during a 1962 1963 expedition. Their encounter was with a Weddell Seal (Leptonychotes weddellii), a deep diver that favors a coastal ice habitat. These bruisers can tip the scales at up to 1,360 pounds (600 kilograms) and they live farther south than any other mammal on EarthThis vintage photograph was taken in 1962 during an Antarctic survey led by biologist Waldo Schmitt, an honorary research associate at the Smithsonian Institution. A crustacean expert, Schmitt travelled the world on multiple research expeditions. The one to Antarctica would be his last. He died in 1977 at the age of 90.
