Very sharp spines - like needles !

I suppose you could get some liquid from it, but not very much - The pads are rather thin ... and very prickly. So it would be difficult, and probably not worth the bother ... unless you were almost dehydrated.

Can you get liquid from these, if say one was stranded in the desert without water? Would be a prickly job!
