 And our reporter Claire Bates is here to tell us exactly what that is. Hi, Claire. Hi, Moira. Now, I have to say on this programme, we love turtles. We do indeed. And that's partly because they play such an important role in keeping our oceans healthy. So green turtles, for example, help to maintain seagrass beds. Loggerheads eat hard-shelled prey and that recycles all those important nutrients.
