Otters

Family bond is really strong among otters. Not only are they close with their mother, but they are also close with their father and siblings. This is why they tend to play a lot as a family. They even build slippery slides using natural materials to easily hit the water just like what we do on the pool. When tamed, otters can play with humans. It was also found out that otter sleep holding hands so that they won’t drift apart from each other.
