Early life history of the Korean seahorse, Hippocampus haema: Evidence for direct settlement and ontogenetic shifts in snout morphology

Journal of Fish Biology, EarlyView.
Abstract Early life‐history traits of seahorses are closely linked to juvenile survival, dispersal potential and the onset of substrate attachment; however, detailed stage‐resolved descriptions remain limited for many Hippocampus species. This study examined reproductive behaviour and early ontogenetic development of the Korean seahorse, Hippocampus ...

Ontogenetic Development of Hyperostosis in the Crevalle Jack Caranx hippos (Linnaeus, 1766) and New Records of Affected Bone Regions

Journal of Fish Diseases, EarlyView.
ABSTRACT Hyperostosis is a non‐pathological condition widely reported in marine teleosts, yet its developmental dynamics and underlying drivers remain poorly understood. This study investigates the ontogenetic progression and anatomical distribution of hyperostosis in Caranx hippos based on a growth series of 39 specimens collected along the Brazilian ...

Anatomy of spinal CSF loss in the American alligator (Alligator mississippiensis)

Journal of Anatomy, Volume 246, Issue 4, Page 575-584, April 2025.
India ink introduced into the cranial cerebrospinal fluid (CSF) compartment of Alligator diffuses along the spinal cord and exits the spinal compartment using perineural flow, resulting in a prominent “ink cuff” forming at the base of the spinal nerve. In Alligator, the region of the ink cuff is drained by a small lymphatic vessel.

An investigation of the functional significance of the pyramidalis muscle using shear wave elastography

Journal of Anatomy, EarlyView.
The pyramidalis (Py) is a small triangular‐shaped anterior abdominal wall muscle, the function of which remains uncertain. We used shear wave elastography to test the hypothesis that Py contributes to stiffness of the linea alba. Our results indicate that Py contraction results in a significant increase in LA stiffness, supporting the previously ...

Computed tomography reveals multiple origins of extreme caudal vertebral pneumaticity in sauropod dinosaurs

Journal of Anatomy, EarlyView.
Here, we present novel CT scan data of caudal vertebrae of six Middle–Late Jurassic sauropods, representing several eusauropod lineages. We synthesise these new data with a comprehensive critical appraisal of purported external and internal evidence for caudal vertebral PSP in Sauropodomorpha.

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Cumulative effects of lifelong systemic excess growth hormone on postcranial skeletal morphology in adult mice

Journal of Anatomy, EarlyView.
Our μCT‐based pilot study reveals size and shape disparity in the adult postcranial skeleton of growth‐hormone model (bGH) mice relative to wild‐type mice. bGH mice have larger and more sexually dimorphic bones, with a systemic radiodensity increase in bony sesamoids and associated, but typically uncalcified, soft tissues.

Layer‐by‐layer soft‐tissue effects on flexion–extension‐dominant passive ex vivo limb joint ROM in quadrupedal mammals: An anatomical contribution to a morphofunctional framework

Journal of Anatomy, EarlyView.
Layer‐by‐layer passive ex vivo assessment of flexion–extension‐dominant limb joint ROM across rabbit, pudu deer, chilla fox and pig revealed joint‐, tissue‐ and taxon‐specific responses to progressive tissue removal. Proximal joints often showed increasing ROM, whereas distal joints often showed non‐monotonic responses.

Human dissection and comparative anatomy: Archaeological evidence for nineteenth‐century anatomical practice at University College London

Journal of Anatomy, EarlyView.
Excavation at University College London revealed more than 8700 human skeletal fragments representing at least 38 individuals, alongside over 800 animal remains. Features consistent with dissection, specimen preparation and curation provide evidence for the use of human and animal material in nineteenth‐century anatomical education, offering rare ...
