Inducible Defenses with a "Twist": Daphnia barbata Abandons Bilateral Symmetry in Response to an Ancient Predator. [PDF]
Predation is one of the most important drivers of natural selection. In consequence a huge variety of anti-predator defenses have evolved in prey species.

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

Developmental role of dpp in the gastropod shell plate and co-option of the dpp signaling pathway in the evolution of the operculum [PDF]
The operculum is a novel structure in gastropod molluscs. Because the operculum shows notable similarities to the shell plate, we asked whether there were an evolutionary link between these two secretory organs.

Expressed sequence tag analysis of genes expressed during development of the tropical abalone Haliotis asinina [PDF]
The tropical abalone. Haliotis asinina. is,in ideal species to investigate the molecular mechanisms that control development. growth, reproduction and shell formation in all cultured haliotids. Here we describe the analysis of 232 expressed sequence tags

Association between shell morphology of micro-land snails (genus Plectostoma) and their predator’s predatory behaviour [PDF]
Predator–prey interactions are among the main ecological interactions that shape the diversity of biological form. In many cases, the evolution of the mollusc shell form is presumably driven by predation.

Conservation of ParaHox genes' function in patterning of the digestive tract of the marine gastropod Gibbula varia [PDF]
Background: Presence of all three ParaHox genes has been described in deuterostomes and lophotrochozoans, but to date one of these three genes, Xlox has not been reported from any ecdysozoan taxa and both Xlox and Gsx are absent in nematodes.
