A new study has found that some sharks possess severe personality traits in them as they are ‘gregarious’ in nature and possess strong connectivity with the society, while the others love remaining in more solitary and inconspicuous environment.
This is the first of its kind of study to show personality traits in these notorious predators.
Scientists explain presence of personalities is not new in animals as many of them possess the quality but these traits are generally defined by individual characteristics like boldness or aggressiveness.
The study was led by the researchers at the Marine Biological Association (MBA) of the UK and the University of Exeter.
For the study, the researchers examined the social personality traits in these creatures by recording the social interactions, under three different habitat types, among the groups of juvenile small spotted catsharks.
The researchers tested ten groups of sharks which were placed in large tanks having three different habitats, which were unique from each other in terms of their level of structural complexity.
Dr David Jacoby, a behavioural ecologist at London’s Institute of Zoology, said, “We found that even though the sizes of the groups forming changed, socially well-connected individuals remained well-connected under each new habitat.”
Jacoby said that the findings were driven by various social preferences which reflected different strategies of the creatures to remain safe.
“Well-connected individuals formed conspicuous groups, while less social individuals tended to camouflage alone, matching their skin colour with the colour of the gravel substrate in the bottom of the tank,” Jacoby added.
The study was published in the journal Behavioral Ecology and Sociobiology.
