Seal Locomotion Explained

Seals exhibit two distinct forms of locomotion in the water, with sea lions and fur seals using their flippers for movement, while true seals rely on their hind flippers, resembling a snake's motion on land. True seals have lost a crucial joint that affects their mobility, resulting in a more awkward way of moving compared to the more agile sea lions, which can walk on all fours. A simple tip to differentiate them: if you see a seal walking on all fours, it's a sea lion!
