I have seen my snake dip his head into his water dish and have a nice long drink many times. The dish is not see-thru and I never approach him when he's drinking so as not to disturb him.
So, has anyone seen the actual mechanism of a BP drinking?
Do they scoop, suck, or lap up the water?
I don't see any head movement, so I am guessing it's either suck or lap, not scoop.
