Lemon sharks 'learn' skills by watching each other
http://www.bbc.co.uk/nature/19484530
Lemon sharks have the ability to learn from each other's behaviour, US scientists have found.
The team compared the performance of inexperienced juvenile sharks working with both trained and untrained partners.
The results showed that sharks working with trained partners could complete tasks more quickly and successfully.
The study is thought to be the first to demonstrate social learning in any cartilaginous fish.
