Which locomotion characteristic shared with *Otariidae* enables the walrus to move effectively on land?
Answer
Ability to rotate rear flippers forward
The walrus exhibits a fascinating duality in its movement patterns that reflects its unique evolutionary position within the Pinnipedia. Specifically regarding terrestrial movement, the walrus shares a key physical capability with the eared seals, or *Otariidae*: the ability to rotate its rear flippers forward underneath the body. This adaptation permits the walrus to bear weight and move efficiently across solid surfaces, allowing it to 'walk' using all four limbs, contrasting with the more restricted movement seen in true seals (*Phocidae*).
