Heart mechanism in a conchostracan, Limnadia lenticularis (L.)

Abstract

THE present evidence suggests that the crustaceans can be divided in two groups according to the mechanism of their heart beat: branchiopods which have a myogenic heart; the other crustaceans with their neurogenic hearts, thus resembling the heart of other arthropods1-4. The branchiopods so far investigated include cladocerans (Daphnia3,5-9, Simocephalus3) and anostracans (Artemia3-4, Eubranchipus4). So far, nothing was known about the physiology of the heart in Conchostraca and Notostraca3. © 1962 Nature Publishing Group.
