GASTROPOD TORSION: A TEST OF GARSTANG'S HYPOTHESIS [PDF]

open access: closedThe 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 ...

At the limits of a successful body plan - 3D microanatomy, histology and evolution of Helminthope (Mollusca: Heterobranchia: Rhodopemorpha), the most worm-like gastropod. [PDF]

open access: yesFront Zool, 2013
Background: Gastropods are among the most diverse animal clades, and have successfully colonized special habitats such as the marine sand interstitial. Specialized meiofaunal snails and slugs are tiny and worm-shaped.

Shape Memory Soft Robotics with Yield Stress Fluids

open access: yesAdvanced Intelligent Systems, Volume 5, Issue 8, August 2023., 2023
Many organisms use non‐Newtonian fluids and pressurized cavities to produce movement. Inspired by these biological motifs, this study 3D prints soft robotics into a yield stress support matrix and retains the support material as the power transmission fluid.
