The dissection was conducted by inserting fine point scissors, from the mantle edge, at the pneumostome
level, initially cutting near the anus and then along the rectum, exposing the pallial cavity roof, folded to the left.
operant conditioning of aerial respiration results in snails attempting to open their respiratory orifice, the pneumostome
, significantly less often (Lukowiak et al., 1996).
situated halfway between front and rear ends of mantle.
This caused the snails to open up their pneumostome
(breathing tube) to get oxygen from the air.
When the snail opened its pneumostome
at the surface, it was given a gentle poke with a wooden stick, causing it to close again.
Tactile stimulation of the lips, tentacles, mantle edge, and pneumostome
effectively produces geotactic responses.
The edge of the mantle skirt is divided into left and right lobes, either side of the pneumostome
. These encircle the base of the neck in the active animal.
