'Eggsploring' Hatching Failure - With Alessia Lavigne

Sea Turtle Stories

Looking at an egg and wondering when and if it ever hosted life is a curiosity most of us are familiar with. But what about sea turtle eggs?

With each sea turtle nest containing anywhere between 60-120 eggs, not all of them hatch into baby sea turtles - some instead exhibit hatching failure. But why do these eggs remain unhatched, and should we even care?

In our third episode, we welcome Alessia Lavigne, a passionate young researcher who believes that hatching failure in threatened sea turtle populations is a cause for concern that demands investigation. After all, eggs hatching successfully is key to ensuring population renewal.

So join Dr Minnie and Alessia, as they crack into the mystery surrounding sea turtle egg development, exploring the reasons behind hatching failure and their implications for sea turtle conservation.
