Sharks have personalities too

Marine biologists from the Bahamas have conducted a study that reveals sharks possess their own distinct personalities – including shy, sociable, curious, calm, risk-taking and fierce. The team captured lemon sharks and introduced each to an unfamiliar tank before documenting how they explored the new surroundings. Their behaviour in social situations with other sharks was also examined. The fish were then tagged and returned to their natural habitat before being re-caught and studied under the same conditions, and it turns out that their behaviour was consistent over both time and circumstance.
