 Biologists used to think turtles belong to the silent majority of reptiles 2, meaning if turtles made sounds, no one is listening. One reptile 1 guy from the 1950s went so far as to call them quote deaf as a post. But it turns out scientists just weren't listening hard enough, because in recent years biologists have identified at least eleven different sounds in the turtle repertoire 3, reported both in and out of the water. But what do they mean? 


 
In the latest attempt to decode 4 turtle talk, researchers tailed giant South American river turtles, xxx, in Brazil over two years' span. They recorded two hundred and twenty hours of audio, capturing six of those eleven sounds. Two of the causes were extremely common, occurring during just about every turtle activity. Other cause the turtle made only during migration 5 or well nesting at night. The findings appear on the journal xx.   
 
The researchers still aren't sure what any of these sounds actually mean, or whether turtles can recognize each other by voice alone. Although more reason they say, to use these sounds in playback experiments, which may get these talking turtles out of their shells.
