‘Social or solitary’

THE most feared predators in the sea have individual personalities that affect how readily they socialise, according to a study by UK scientists.

Individual sharks, studied in groups of 10, showed consistent social habits — either forming groups with other sharks or finding camouflage on their own.

When a group was shifted into a new environment, individual sharks showed the same patterns of behaviour.

This is the first study to show that sharks have their own personalities.

The research was done in large tanks at the Marine Biological Association of the UK, in Plymouth, in collaboration with the University of Exeter.

The findings appear in the journal Behavioural Ecology and Sociobiology.
