Caption: Like a drop on a wine glass the venom tear runs down the groove. The surface tension acting on the venom is the dominant physical force underlying envenomation. And venom is a non-Newtonian fluid. It sticks when necessary while waiting for prey whereas any break in the prey's skin acts as a venom attractant and soaks the venom into the deeper tissues.
