>> Your experience with the yellow mud sounds like my mud turtles too.
>>When I am feeding one, the other turtle across the room sees this and starts going nuts. But it could also be like your turtle in that he SMELLS what I am feeding. In any case, I think they are more perceptive than we might think.

Oh I think so too, they've got it going on in those brains but you have to stop & pay attention to see how much is there.
It's a sight thing too.
Before I started breeding mealworms myself I used to buy them in those little white tubs. My mud recognized that tub & every time he'd see me with it in my hand he'd go nuts. Now he doesn't reconize any particular mealworm container so he never knows when the mealies are on the way. I kind of miss watching him go nuts. lol
