How often do you deep clean?

[Karla]

Very simple. To tarantulas water bowls are like potholes around their retreat; they could stumble over them when they have to race back inside when there's predator or other hazard. They need a smooth, fast track to get to safety.

My Phlogius crassipes loves playing in her water when she is shedding.

"An exuvia (plural exuviae) is the cast-off outer skin of an arthropod after a moult. In some species the exuvia is eaten soon after the moult although in other species it is left. For example, the exuviae of cicadas can often been seen on the surface of trees."

However, exuvium is a word, I was wrong about that - it simply is not what we're referring to here. Close, though.

I wonder why there is a discrepancy in usage. I'd be delighted to talk about it more in chat so we can avoid hijacking the thread any more than we have. In the meantime, as science educator I'm bound to the usage accepted by textbooks and peer-reviewed arachnology journals.
