Which animals hold hands in group?

Certain species of animals are known to hold hands or exhibit similar behaviors to maintain group cohesion. For instance, sea otters often hold paws while resting in groups to prevent drifting apart. Additionally, some primates, like chimpanzees and gorillas, may hold hands or link arms while moving together, reinforcing social bonds within their groups. This behavior is a demonstration of their social nature and the importance of unity in their communities.
