Torsion
The developmental process in gastropods where one side of the body grows faster than the other, causing the visceral mass to twist is called torsion. This torsion usually causes the anus and gills to end up above the head in adult gastropods.
Gastropoda is the molluscan class that includes members that undergo embryonic torsion. Torsion is a unique process in which the visceral mass of the developing mollusk rotates 180 degrees, bringing the anus above the head. This characteristic is a defining feature of the Gastropoda class.
