Lab Notes: Why do whales strand en masse?

Every now and again, dozens or even hundreds of perfectly healthy looking whales strand themselves on a beach. 

And despite people's best efforts, many — if not all of them — will die. 

So why do whales strand themselves, and why do they seem to do it at the same locations? 

This episode was first broadcast in August 2025.
