I'm not sure about mine, never thought to take note, so I'll have to get back to you on this.
Meanwhile, now I'm wondering if they coil the opposite way if they live below the equator?(like water going down a sink drain)
"Objects not attached to the surface of the earth (water in a sink going down a drain) will create a vortex going the opposite direction. So in the Northern hemisphere, it moves clockwise. In the Southern hemisphere, it moves counter clockwise. On the equator, water goes straight down."
