Gastropod snails in the genus Crepidula have emerged as model systems for studying a
metazoan super clade, the Spiralia. Recent work on one species in particular, Crepidula …

Photoreception is a ubiquitous sensory ability found across the Metazoa, and photoreceptive
organs are intricate and diverse in their structure. Although the morphology of the compound …

Larvae of the marine gastropod Crepidula fornicata must complete a transition from the
plankton, where they are highly dispersed, to an aggregated group of benthic adults …

Effective population size (N e) is a measure of genetic drift and is thus a central parameter in
evolution, conservation genetics and invasion biology. Interestingly, in native marine …

Whole mount in situ hybridization (WMISH) is a technique that allows for the spatial
resolution of nucleic acid molecules (often mRNAs) within a'whole mount'tissue preparation …

The calyptraeid gastropod Crepidula fornicata is the object of considerable research
attention, due to its invasive status in the North-Eastern Atlantic, its introduction to habitats …

The history of developmental studies on cephalopods is briefly surveyed, from the middle of
the 19th century to the present. An early phase was marked by many technical limitations …

Background Spiral cleavage is a remarkably conserved pattern of embryogenesis present in
animals of the clade Spiralia, such as annelids, molluscs, flatworms and nemerteans …

Stereotypic cleavage patterns play a crucial role in cell fate determination by precisely
positioning early embryonic blastomeres. Although misplaced cell divisions can alter …
