@newyorkaquarium: When you visit Sea Cliffs, you will often see our sea otters grooming each other. Grooming one another helps strengthen their social bonds. Sea otters are semi-social. While they often hunt and forage alone, they regularly gather together in large groups called rafts to rest. Resting together in rafts helps to protect them from predators and strong ocean currents. #seaotters #newyorkaquarium 🎥: Keeper Olivia
