An article published in the journal “Nature” reports the results of a study of the skull of Latimeria chalumnae, one of the two species of coelacanth existing today. A team of researchers led by Hugo Dutel of the British University of Bristol subjected several specimens to very sophisticated tests to create reconstructions of their skulls and brains from the fetal state to the adult state. The aim is to study these fish considered a living fossil to better understand the evolution of the skull in vertebrates and also the reason why the coelacanth brain occupies only 1% of the cranial cavity.
