“…Cephalopods are reported to accumulate (e.g. : Storelli et al 2005 ; Seixas et al 2005 ; Seixas and Pierce 2005 ; Raimundo et al 2005 ; Napoleao et al 2005 ; Raimundo and Vale 2008 ; Lacoue-Labarthe et al 2008 ; Bustamante et al 2008 ; Raimundo et al 2009 , 2010b ; Pernice et al 2009 ; Lourenco et al 2009 ; Galitsopoulou et al 2009 ; Pereira et al 2009 ; Cirillo et al 2010 ; Lacoue-Labarthe et al 2012 ), and be sensitive to heavy metals (Raimundo et al 2010a ; de Polo and Scrimshaw 2012 ; Semedo et al 2012 ), so care should be taken to ensure these are monitored and maintained within normal ambient ranges.…”

Cephalopods have been utilised in neuroscience research for more than 100 years particularly because of their phenotypic plasticity, complex and centralised nervous system, tractability for studies of learning and cellular mechanisms of memory (e.g. long-term potentiation) and anatomical features facilitating physiological studies (e.g. squid giant axon and synapse). On 1 January 2013, research using any of the about 700 extant species of “live cephalopods” became regulated within the European Union by Directive 2010/63/EU on the “Protection of Animals used for Scientific Purposes”, giving cephalopods the same EU legal protection as previously afforded only to vertebrates. The Directive has a number of implications, particularly for neuroscience research. These include: (1) projects will need justification, authorisation from local competent authorities, and be subject to review including a harm-benefit assessment and adherence to the 3Rs principles (Replacement, Refinement and Reduction). (2) To support project evaluation and compliance with the new EU law, guidelines specific to cephalopods will need to be developed, covering capture, transport, handling, housing, care, maintenance, health monitoring, humane anaesthesia, analgesia and euthanasia. (3) Objective criteria need to be developed to identify signs of pain, suffering, distress and lasting harm particularly in the context of their induction by an experimental procedure. Despite diversity of views existing on some of these topics, this paper reviews the above topics and describes the approaches being taken by the cephalopod research community (represented by the authorship) to produce “guidelines” and the potential contribution of neuroscience research to cephalopod welfare.

“…This geochemical tracer clearly characterizes the anthropogenic nature and the origin of accumulated Pb in the marine geosphere (Alleman et al, 1999;Angelidis et al, 2011;Boyle et al, 2014;Bridgestock et al, 2018;Kelly et al, 2009;Lee et al, 2014;Noble et al, 2015;Patterson et al, 1976;Stukas and Wong, 1981;Veron et al, 1993Veron et al, , 1998Veron et al, , 1999Wu et al, 2010). Data on lead isotope ratios are scarce for marine ecosystems (Caurant et al, 2006;Ip et al, 2005;Li et al, 2020;Michaels and Flegal, 1990;Raimundo et al, 2009;Smith et al, 1990Smith et al, , 1992Spencer et al, 2000;Stewart et al, 2003), and non-existent for sharks. Lead bears insignificant biological or physical isotope fractionation within the marine ecosystem where its isotope imprint is a pertinent marker of anthropogenic sources (Flegal et al, 1987;Michaels and Flegal, 1990;Smith et al, 1990).…”
