Chinese Mystery Snails (watercolour 5 x 7 in.) Sold
Being air breathers, these giant snails don't wander into deep water. Each snail must periodically climb up to break the surface with the edge of its mantle curled into a tube, to freshen the air in the large space inside its shell. On these snails I see two mantle flaps, one on each side of the head - but only the one on the right side forms a breathing tube, translucent and delicate like a little mushroom. The other is a simple flap of skin that may function as a gill.
