Correcting a 135-year error: Limulidae Leach, 1819 (Chelicerata, Xiphosura) is the proper authority, not Limulidae Zittel, 1885

, 2021
The horseshoe crab Limulus polyphemus (Linnaeus, 1758) is a famous species, renowned as a ‘living fossil’ (Owen, 1873; Barthel, 1974; Kin and Błażejowski, 2014) for its apparently little-changed morphology for many millions of years.

Evolutionary and functional substitution of extrinsic musculature in Solifugae (Arachnida)

Journal of Morphology, Volume 281, Issue 12, Page 1524-1533, December 2020., 2020
The proximal region of the locomotory system in Solifugae is characterized by fused coxae. Using micro‐computed tomography scans, we investigated the morphology at the interface between prosoma and legs to highlight the modifications associated with impaired mobility of the coxae. The complex arrangement of the coxa‐trochanter muscles is interpreted in

DataSheet_3_New perspectives on the evolutionary history of xiphosuran development through comparison with other fossil euchelicerates.docx

, 2023
IntroductionEuchelicerata is a diverse group encompassing Xiphosura, Chasmataspidida, Eurypterida, and Arachnida. Xiphosura represents an extant group with a rich fossil record dating back to the Ordovician period.

Visual pathways in the brain of the jumping spider Marpissa muscosa

Journal of Comparative Neurology, Volume 528, Issue 11, Page 1883-1902, July 15, 2020., 2020
Most spider species possess eight eyes, of which two (the principal eyes) are used for object discrimination, whereas the other three pairs (secondary eyes) detect movement. Jumping spiders are particularly renowned for their visual abilities and we studied the neural substrate for visual processing in the jumping spider Marpissa muscosa.

The circulatory system of Penaeus vannamei Boone, 1931—Lacunar function and a reconsideration of the “open vs. closed system” debate

Journal of Morphology, Volume 281, Issue 4-5, Page 500-512, April-May 2020., 2020
The morphology of the hemolymph circulatory system of the decapod Penaeus vannamei is investigated. As well as the complex vascular system, distinct lacunae are investigated three‐dimensionally and interpreted on a functional level. Abstract The morphology of hemolymph circulatory systems has been studied in many arthropod groups over the past decades.

Ultrastructure of book gill development in embryos and first instars of the horseshoe crab Limulus polyphemus L. (Chelicerata, Xiphosura)

Frontiers in Zoology, 2012
Background The transmission electron microscope (TEM) is used for the first time to study the development of book gills in the horseshoe crab. Near the end of the nineteenth century the hypothesis was presented for homology and a common ancestry for ...

The eyes of Limulus polyphemus (Xiphosura, Chelicerata) and their afferent and efferent projections

Arthropod Structure & Development, 2006
The visual system of the American horseshoe crab Limulus polyphemus (L. polyphemus) is an important preparation for studying the photoresponse, the circadian modulation of the photoresponse and visual information processing. Given its unique position in phylogeny the structure of its visual system also informs studies of the relationships among ...

Data from: A critical appraisal of the placement of Xiphosura (Chelicerata) with account of known sources of phylogenetic error

, 2019
Horseshoe crabs (Xiphosura) are traditionally regarded as sister to the clade of terrestrial chelicerates (Arachnida). This hypothesis has been challenged by recent phylogenomic analyses, but the non-monophyly of Arachnida has consistently been ...
