Clade‐wide morphological and functional variation of the sauropsid columella

open access: yesThe Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Different shape but the same topographical complexity—The lingual gross anatomy of the Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite the distinctly different shapes of their tongues, the tongue gross anatomy of Saimaa ringed seal closely resembled that of Baltic ringed seal. There were no differences in the extrinsic and intrinsic tongue muscles or their associated vascularization and innervation between Saimaa and Baltic ringed seals.

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

open access: yesThe Anatomical Record, EarlyView.
Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, particularly in Pleurodira.
