Evidence that gastropod torsion is driven by asymmetric cell proliferation activated by TGF-β signalling [PDF]
Biology Letters, 2011 Gastropods are characterized by their asymmetric bodyplan, which develops through a unique ontogenetic process called ‘torsion’. Despite several intensive studies, the driving force of torsion remains to be determined. Although torsion was traditionally believed to be driven by contraction of the retractor muscle connecting the foot and ...

GASTROPOD TORSION: A TEST OF GARSTANG'S HYPOTHESIS [PDF]
The Biological Bulletin, 1985 Torsion occurs in gastropod molluscs as a 180° twisting of the shell and viscera relative to the head and foot of the veliger larva. Garstang (1928, 1929) proposed, and it has since become widely accepted, that torsion functions as a larval defense by allowing veligers to first pull the head into the shell, then sealing the aperture with the foot and ...

A Method for Quantifying, Visualising, and Analysing Gastropod Shell Form. [PDF]
PLoS ONE, 2016 Quantitative analysis of organismal form is an important component for almost every branch of biology. Although generally considered an easily-measurable structure, the quantification of gastropod shell form is still a challenge because many shells lack ...

Gastropod phylogenetic torsion – arising of a class [PDF]
Folia Malacologica, 2016 In the paper the author reconsiders the problem of phylogenetic torsion, which has for more than a hundred years been a subject of interest of numerous malacologists, and is still unclear.

Proteomic analysis of trochophore and veliger larvae development in the small abalone Haliotis diversicolor [PDF]
BMC Genomics, 2017 Background Haliotis diversicolor is commercially important species. The trochophore and veliger are distinct larval stages in gastropod development. Their development involves complex morphological and physiological changes.

Growth and morphogenesis of the gastropod shell. [PDF]
Proc Natl Acad Sci U S A, 2019 Significance Mollusc shells are emblematic of the morphological diversity in nature. They are important models for understanding the evolution of form; they are all variations on the same basic geometrical groundplan, their shapes can be directly related

Israel Journal of Ecology & Evolution, 2023 We studied and found that the populations of two gastropod species in the inter-tidal zone of the Red Sea at Eilat demonstrate a predominantly dextral chirality of their shells.
