Neurogenesis 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 کاملGrowth increments and biomineralization process in cephalopod statoliths.
A study on morphological, structural and biochemical composition of Sepia officinalis and Loligo vulgaris statoliths and statocyst endolymph was undertaken with the aim of determining the major factors affecting the deposition process of statolith formation and to clarify the cause for the poor definition of the growth increments in S. officinalis statoliths. It is suggested that the different ...
متن کاملA Preliminary Analysis of Sleep-Like States in the Cuttlefish Sepia officinalis
Sleep has been observed in several invertebrate species, but its presence in marine invertebrates is relatively unexplored. Rapid-eye-movement (REM) sleep has only been observed in vertebrates. We investigated whether the cuttlefish Sepia officinalis displays sleep-like states. We find that cuttlefish exhibit frequent quiescent periods that are homeostatically regulated, satisfying two criteria...
متن کاملNew protocols to improve the deposition and hatching of Sepia officinalis' eggs.
The objective of this study was the development of hatching protocols in controlled conditions to obtain juveniles, in order to restock and increase the resource of Sepia officinalis. The study was divided into the following phases: development and application of artificial surfaces at specific sites of the Molise coast in Italy; induction of eggs hatching and juveniles maintenance under contro...
متن کاملPreliminary Results on the Daily and Seasonal Rhythms of Cuttlefish Sepia officinalis (Linnaeus, 1758) Locomotor Activity in Captivity
This research was aimed at characterizing the daily rhythms of locomotor activity of cuttlefish Sepia officinalis (Linnaeus, 1758), a promising aquaculture species, in a captive environment. Cuttlefish were distributed within two tanks equipped with infrared photocells, allowing the monitoring of locomotor activity continuously from August to February. Results showed a preference of cuttlefish ...
