Perinatal cognition

Most of cephalopods mate only once in their life and die. As a consequence, no care is provided to eggs or juveniles. We showed that embryos are sensitive to several environmental stimuli mainly through vision or smell. They can learn to recognize predators as well as prey. Embryonic learning will alter juveniles’ behavior or prey preference. Comparative studies are led about the composition of the perivitellin fluid between cuttlefish and squid species with different egg capsule opacity in collaboration with Asian labs (Taiwan, Japan). In general, embryonic inductions and their consequences on juveniles’ development are one of our core research.
