“…In scorpions and spiders however, differing numbers of pairs of cardiac arteries can be observed (Randall, ; Wirkner and Prendini, ; Klußmann‐Fricke et al, ; Huckstorf et al, ). The only other chelicerate taxon in which complex cardiac arteries can be observed is Xiphosura, but these are additionally characterized by numerous anastomoses (Göpel and Wirkner, ). Such anastomoses between cardiac arteries could not be observed in Arachnopulmonata (Wirkner and Prendini, ; Huckstorf et al, ; this study).…”

“…In more basal spiders, there are also two pairs of pulmopericardial sinuses (Wirkner and Huckstorf, ; Huckstorf et al, 2015) while in more derived spiders, like C. salei , only one pair is described (Huckstorf et al, ) as the number of pulmopericardial sinuses always correlates with the number of book‐lungs. It should also be noted that sinuses (so‐called branchiopericardial sinuses) connecting the respiratory structures (i.e., the book‐gills) are also present in Xiphosura (Göpel and Wirkner, and references therein).…”

“…Recent studies have demonstrated that vascular systems in certain arthropod taxa, such as certain Malacostraca (Sandemann, ; McGaw, ; McGaw and Duff, ; Wirkner and Richter, ; Huckstorf and Wirkner, ; Keiler et al, ), certain Chilopoda (Wirkner and Pass, ) and also many Chelicerata (Wirkner and Prendini, ; Klußmann‐Fricke et al, ; Huckstorf et al, ; Göpel and Wirkner, ) are highly complex. In some arachnopulmonate taxa, this level of complexity has been observed, not only in the hemolymph vascular systems (HVS) in general, but especially in the arterial systems of the prosomal ganglion.…”

“…As part of a comparative survey on the evolutionary morphology of the HVS in chelicerates (see, e.g., Wirkner and Prendini, ; Klußmann‐Fricke et al, , in press; Huckstorf et al, ; Göpel and Wirkner, and references therein), this article addresses the HVS in Amblypygi and Uropygi. The principal aim of this study is twofold: first, to visualize and describe in detail the HVSs of various representatives of Amblypygi and Uropygi and, second, to compare the resulting data with the available literature regarding the HVS in the aforementioned taxa (Causard, ; Börner, ; Schminkewitsch ; Buxton, ; Kästner, ; Weygoldt, ) and in other arachnopulmonates (i.e., Scorpiones and Araneae; Huckstorf et al, ; Klußmann‐Fricke et al, , in press and references therein).…”

Although the circulatory system of arthropods has long been considered as rather simple, recent studies have demonstrated that in certain arthropod taxa, such as Malacostraca, some Chilopoda and also many Chelicerata, the vascular systems in particular are rather complex. Furthermore, a recent study has revealed that the prosomal ganglion of scorpions and spiders is supplied by an intricate network of arteries, the complexity of which bears a close resemblance to that of vertebrate capillary systems. In this study, we analyzed the hemolymph vascular systems of various species of Pedipalpi (i.e., Amblypygi and Uropygi). By combining modern techniques, such as MicroCT and cLSM, with computer-based 3D-reconstruction, we were able to produce comprehensive visualizations and descriptions of the vascular systems. Despite the lack of well-corroborated phylogenetic hypotheses on arachnid relationships and the controversial assertion of relationships between the pulmonate arachnids, we aim to elucidate the evolution of complex vascular systems in Arachnida. By comparing these highly complex vascular systems not only with each other, but also with other pulmonate arachnids, we found numerous detailed correspondences in the general branching pattern as well as in the supply patterns of the prosomal ganglion. We argue that these numerous and detailed correspondences by their absence in other arachnids i.e. aplumonates, support Arachnopulmonata. J.

“…Horseshoe crabs are not true crabs, neither crustacean; they are marine arthropods more closely related to arachnids (a group that includes spiders and scorpions) than to crustaceans (a group that includes true crabs, lobsters, and shrimp). Horseshoe crabs are often called "living fossils" because their ancestors date back to 450 million years before the Triassic period (8).…”

Since the original observations by Bizzozero and Osler, we have seen tremendous advances in the understanding of platelets far beyond haemostasis and the restoration of injured endothelium. In this minireview on platelets, we will briefly outline their historical description and the importance of their evolution, focusing on a 450 million years old living fossil of Limulus polyphemus, a marine chelicerate arthropod, which helped researchers explain the basis for the immunity role of platelets and make correlations with platelet ultrastructure and function. In addition, the impact of the Limulus Amoebocyte Lysate (LAL) test for modern medicine is highlighted. The role of platelets in cardiovascular diseases, their relevance in arterial and venous thrombosis, and the utilization of antithrombotic drugs as therapeutic agents are also reported.Furthermore, platelet receptors are crucial in aggravating or mitigating other diseases, such as cancer and infections, which can recruit cells and have numerous interactions in a process recently coined "NETosis formation", which is also briefly depicted.

Interpreting fossilized nervous tissues

et al. 2023

Paleoneuranatomy is an emerging subfield of paleontological research with great potential for the study of evolution. However, the interpretation of fossilized nervous tissues is a difficult task and presently lacks a rigorous methodology. We critically review here cases of neural tissue preservation reported in Cambrian arthropods, following a set of fundamental paleontological criteria for their recognition. These criteria are based on a variety of taphonomic parameters and account for morphoanatomical complexity. Application of these criteria shows that firm evidence for fossilized nervous tissues is less abundant and detailed than previously reported, and we synthesize here evidence that has stronger support. We argue that the vascular system, and in particular its lacunae, may be central to the understanding of many of the fossilized peri‐intestinal features known across Cambrian arthropods. In conclusion, our results suggest the need for caution in the interpretation of evidence for fossilized neural tissue, which will increase the accuracy of evolutionary scenarios.
