Larval Muscle Contraction Fails to Produce Torsion in a Trochoidean Gastropod
The Biological Bulletin, 2001 The causes and effects of ontogenetic torsion in gastropods have been debated intensely for more than a century (1-19). Occurring rapidly and very early in development, torsion figures prominently in shaping both the larval and adult body plans. We show that mechanical explanations of the ontogenetic event that invoke contraction of larval retractor ...

The Adaptive Significance of Gastropod Torsion
Evolution, 1966 Unique among mollusks, the Gastropoda are characterized by a curious asymmetry, resulting from a rotation of the visceral hump and shell. Thus in the earlier stages of their embryonic development, gastropods have the same arrangement of parts as other mollusks, with the rudiments of the mantle cavity, gills, coelomic ducts, and associated structures at

Gastropod ontogenetic torsion: Developmental remnants of an ancient evolutionary change in body plan
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2003 AbstractA dramatic morphogenetic movement (‘ontogenetic torsion’) during the development of gastropods has been proposed as a recapitulation of the original developmental departure that established the novel gastropod body plan. Nevertheless, speculative literature about ontogenetic torsion and its evolutionary significance has far outstripped ...
