This skull has large canines and highly adapted five-pointed premolars, a long snout and large eye sockets. When I first saw the photo of those terrifying teeth I thought they belonged to a long extinct creature -- but the truth is quite surprising.
It is one of the most common animals of its species and there are at least 10 million of them alive today.
The skull belongs to a crabeater seal -- a species that is common in Antarctica -- and lives on floating pack ice. Despite the name, they feed almost entirely on krill and their unusually shaped teeth make excellent filters.
