“…[44] demonstrated a significant in vitro inhibition of cytosolic CA by Ag + , Cd 2+ , Cu 2+ and Zn 2+ in the gills of the crabs Callinectes sapidus and Carcinus maenas. The inhibition was species-specific with a binding affinity for the metals one thousand times weaker in C. maenas with respect to C .…”

“…Most deficiencies of peristaltic design can be summed up by stating that peristaltic pumps lack effective coordination between the fluid that is entering the contractile region and the fluid that is leaving it [51]. This, of course, does not mean that peristaltic pumps can not be improved, or that backflow cannot be exploited to the animals advantage [85,88]. Backflow in arthropod peristaltic pumps is Cell.…”

“…Although sufficiently 728 J. Xavier-Neto et al Evolutionary origins of pumping organs sophisticated on its own, the arthropod dorsal vessel was initially designed as a peristaltic organ, not as a chambered pump [87,88]. As discussed above, its blueprints reflect a fundamentally different approach to the problem of fluid propulsion than the one chosen for vertebrates and molluscs in their chambered hearts.…”

“…Two types of recurrent electrical activities (perhaps not APs) of myocardial fibers are distinguished in Arthropoda. In Scolopendra cingulata and Lithobius forficatus , this rhythm was considered as myogenic, however, the additional oscillations at their plateau phase as neurogenic (Hertel, Wirkner, & Pass, ). In Peripatopsis , no plateau and corresponding oscillations were observed, and because the activity resembled those of pacemaker‐like potentials, they were concluded to be myogenic (Hertel et al, ).…”

“…TTX obliterates the cardiac electrical activity of S. cingulata , but at “heroic doses” of 300 μM (Gibson & Lang, ; Hertel et al, ). Interestingly, this obliteration is short term, because the rhythmicity is resumed after 25 min albeit the absence of plateau phase (Hertel et al, ). However, it is not clear whether TTX was applied only for 1 min or it was present up to 25 min.…”
