<p>Cephalopods are new evolutionary and ecological models.<br />
By their phylogenetic position (Lophotrochozoa, Mollusca),<br />
they provide a missing master piece in the whole puzzle of<br />
neurodevelopment studies. Their derived and specific nervous<br />
system but also their convergence with vertebrates offer<br />
abundant materials to question the evolution and development<br />
of the nervous system of Metazoa (evo-devo studies). In<br />
addition, their various adaptions to different modes of life<br />
open new fields of investigation of developmental plasticity<br />
according to ecological context (eco-evo-devo approach). In<br />
this paper, we review the recent works on cephalopod nervous<br />
developmental investigations. We show how cephalopods, and<br />
especially Sepia officinalis, an animal of economical interest,<br />
can be used as suitable models to extend our knowledge on<br />
cephalopod ecology and on nervous system evolution among<br />
molluscs.</p>
