Weddell Seal

The Weddell seal is the most southerly breeding mammal on Earth, found year-round on the fast ice surrounding Antarctica. These large, docile seals are known for their haunting underwater vocalisations and can hold their breath for over an hour while diving to depths exceeding 600 metres. Their placid temperament and curiosity towards humans make them a highlight of any Antarctic expedition.
