: Cephalopod mollusks are included since January 2013 in the Directive 2010/63/EU which regulates the use of animals for scientific research purposes. Killing animals solely for tissue removal does not require authorization from the National Competent Authority under Directive 2010/63/EU and its transposition into national legislation. Experiments included in this work have been carried out on samples taken from animals humanely killed under a project license from NCA (Italy; Aut. No 19/2014-PR) or as freshly dead from local fishermen following principles stated in Directive 2010/63/EU.
