The cuttlefish Sepia officinalis (Sepiidae, Cephalopoda) constructs cuttlebone from a liquid-crystal precursor
Cuttlebone, the sophisticated buoyancy device of cuttlefish, is made of extensive superposed chambers that have a complex internal arrangement of calcified pillars and organic membranes. It has not been clear how this structure is assembled. We find that the membranes result from a myriad of minor membranes initially filling the whole chamber, made of nanofibres evenly oriented within each memb...

متن کاملNeurogenesis in Cephalopods: “eco-evo-devo” Approach in the Cuttlefish Sepia Officinalis (mollusca-cephalopoda)
Cephalopods are new evolutionary and ecological models. By their phylogenetic position (Lophotrochozoa, Mollusca), they provide a missing master piece in the whole puzzle of neurodevelopment studies. Their derived and specific nervous system but also their convergence with vertebrates offer abundant materials to question the evolution and development of the nervous system of Metazoa (evo-devo s...
متن کاملAccommodation in the cuttlefish (Sepia officinalis).
We have studied natural accommodation in the eye of six specimens of cuttlefish (Sepia officinalis) as they were fed with fish and shrimp. Using infrared photoretinoscopy, we observed (1) that the resting refractive state of the cuttlefish was emmetropic or slightly hyperopic, (2) that accommodation took place only a fraction of a second before a strike and (3) that accommodation focused select...
متن کاملIsolation and characterization of new polymorphic microsatellite markers from the cuttlefish Sepiella maindroni (Cephalopoda; Sepiidae).
Fifteen new polymorphic microsatellite loci were developed for the cuttlefish Sepiella maindroni. In 32 individuals from a wild population of coastal Ningde, Fujian Province, China, the number of alleles at these loci varied between 2 and 12, with an average of 5.86. The mean observed and expected heterozygosities were 0.6917 and 0.5993, respectively. Among these polymorphic microsatellite loci...
