“…S21). This result confirms the well-known fact that the heart rate is slower at lower temperatures and as the snail grows ( 31 – 33 ). A detailed description of this experiment is given in sections 8 and 9 of Supplementary Text.…”

“…In Drosophila melanogaster , the HR is age dependent and at the prepupal stage it reaches ~170 beats min −1 (Choma, Suter, Vakoc, Bouma, & Tearney, ). Note that at this stage, flies are “white‐translucent” that enables a convenient observation of heartbeat similar to other invertebrates (Beasley & Dowse, ; V. L. Zhuravlev et al, ). In some studies, they are placed in either physiological solutions or in a “drop of water which increased the intensity of the illumination and served to help keep the pupa” (Beasley & Dowse, ) at experimentally controlled temperatures up to 37°C.…”

“…For more than a century, the hearts of invertebrates have been subjects of research in physiology (Kodirov, Zhuravlev, Pavlenko, Safonova, & Brachmann, ; Ransom, ; Watson & Hoshi, ; V. L. Zhuravlev et al, ). The basics of the cardiac physiology of vertebrates and invertebrates are similar (Carlson, ).…”

“…By fixing the individual eggs into glass block, authors were able to observe the development and HR of the same embryos (Crozier & Stier, ). A recent study documented the advantages of experiments on the heart in embryos whose development occurs within the egg (V. L. Zhuravlev et al, ). The monitoring of HR in invertebrates, including the crustacean, has been given serious consideration by using infrared phototransducers (Depledge & Andersen, ).…”

Great interest in the comparative physiology of hearts and their functions in Animalia has emerged with classic papers on Limulus polyphemus and mollusks. The recurrent cardiac activity-heart rate-is the most important physiological parameter and when present the kardia (Greek) is vital to the development of entire organs of the organisms in the animal kingdom. Extensive studies devoted to the regulation of cardiac rhythm in invertebrates have revealed that the basics of heart physiology are comparable to mammals. The hearts of invertebrates also beat spontaneously and are supplied with regulatory nerves: either excitatory or inhibitory or both. The distinct nerves and the source of excitation/inhibition at the level of single neurons are described for many invertebrate genera. The vertebrates and a majority of invertebrates have myogenic hearts, whereas the horseshoe crab L. polyphemus and a few other animals have a neurogenic cardiac rhythm. Nevertheless, the myogenic nature of heartbeat is precursor, because the contraction of native and stem-cellderived cardiomyocytes does occur in the absence of any neural elements. Even in L. polyphemus, the heart rhythm is myogenic at embryonic stages.
