Sounds Fishy

Cornish fish moving north with climate change may struggle to understand Scouse counterparts, study says, making it harder for them to mate. Experts believe the fish, which make sounds with their swim bladders to attract mates, may have regional accents – and if males cannot “chat up” females who speak a different dialect it could threaten their ability to breed. Jeff and Anthony discuss the idea of animal dialects, and what it might mean for nature.
