Evidence that gastropod torsion is driven by asymmetric cell proliferation activated by TGF-beta signalling. [PDF]
Biol Lett, 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 ...

Expression Pattern of Nitric Oxide Synthase during Development of the Marine Gastropod Mollusc, Crepidula fornicata. [PDF]
Genes (Basel), 2021 Nitric Oxide (NO) plays a key role in the induction of larval metamorphosis in several invertebrate phyla. The inhibition of the NO synthase in Crepidula fornicata, a molluscan model for evolutionary, developmental, and ecological research, has been ...

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 TORSION: A TEST OF GARSTANG'S HYPOTHESIS
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 ...

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.

PeerJ, 2014 The molluscan shell can be viewed as a petrified representation of the organism’s ontogeny and thus can be used as a record of changes in form during growth.
