“The EU directive on “the protection of animals used for scientific purposes“, which member states must incorporate into their national laws by January 2013, for the first time extends protections to cephalopods as well as vertebrate lab animals.
“[…] Participants at the Naples meeting criticized the ‘mammal-centric language’ of the directive. For example, the text of the regulation recommends that analgesics and local or total anaesthesia be used to reduce animals’ pain, when necessary. But researchers do not know much about how pain signals are transmitted in the nervous systems of cephalopods, and what effects anaesthetics would have on them. It is possible that such measures could actually cause more harm to the animal, or seriously interfere with the biological mechanisms being investigated.”
