I have noticed this "piling behavior" (that's what I call it) in my newts (Eastern newts, Firebellies). Does anyone know if there is a technical term or reason for it? Do most species of newts do it? (In humans, they're called "puppy piles.")
I know the behaviour is normally called "gregarious". Maybe it's something that helps them prevent freezing in the winter? Just throwing a suggestion here, maybe someone knows more about this behaviour. I'm sure there's a reason for it.
Gregariousnes is often a strategy of defence. Maybe morphs have this behaviour because if for example, a small snake finds their hide it will eat one..or a couple...but maybe not all. If there were only one morph in that hide it would be eaten...but hiding together the % of being the one the snake eats is smaller.
Or maybe they do this just because there´s no more hiding places xD
who knows...
