Crabeater seal (Lobodon carcinophagus) resting on ice. Despite the name, it does not eat crabs but uses specialised teeth to sieve krill out of the water. It feeds principally at night. It is found on and below the Antarctic pack ice, moving north at the end of summer. The crabeater seal is often scarred due to fighting and attacks by its main predator, the leopard seal. It can reach a length of 2.4 metres and weigh some 300 kilograms. Photographed in Antarctica.
