Evolution of Duplicated Hox Gene Clusters in Land Snails and Slugs. [PDF]
J Exp Zool B Mol Dev EvolMolluscs of the order Stylommatophora underwent an ancient genome duplication. We show that stylommatophoran snails and slugs have two broken and incomplete Hox gene clusters; HoxA generally has 9 genes, HoxB usually has 7 genes. After duplication of an ancestral 11‐gene Hox cluster, there was patchwork retention of duplicated genes.

Ontogeny, muscle scars, colour pattern and predation marks in a Silurian orthoceratid cephalopod [PDF]
Acta Palaeontologica PolonicaMuscle scars, embryonic shell, colour pattern and intraspecific variation are known together in a very limited numberof straight shelled cephalopods, leading to uncertainty in the classification of the subclass Orthoceratoidea.

Vertical distribution and abundance of juvenile cephalopods in Aegean Sea
Scientia Marina, 2003 This study was carried out in northern (Saros Bay) and southern (Gökova Bay) parts of the Aegean Sea. In pelagic samplings, Hamburg Plankton Net (HPN) was used. Samplings were done out at four different periods of a 24 hour day; sunrise, noon, sunset and
