Yelled For Assisstance
When they turned their attention away from the immediate area and onto the horizon, they saw a metallic saviour in the form of a fishing boat. If they had been able to communicate with one another, they would have yelled for assistance by saying “help!” if they had done so.
It was unnecessary to yell because the employees who were working on the boat had already observed the bears in the distance and were aware of their existence. Consequently, the bears’ presence was already known to those personnel. They also saw the bear cub’s mother swim away from the group in the opposite direction from where they were heading.
