Perhaps you’ve never thought too deeply about the personalities of sharks, but a group of scientists from the University of Exeter has been doing just that. They have found that sharks have different personalities which affects how they interact socially with other sharks.
In research published in Behavioral Ecology and Sociobiology, the scientists reported that some sharks are “loners” while others prefer to spend time in a group. This basically reflects two different ways of dealing with predators: the “safety in numbers” approach versus the “hide among these reeds by myself” approach. Changing the sharks’ surroundings or shark groups didn’t change their personalities or social inclinations.
