Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

The Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin

The Anatomical Record, EarlyView.
Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

Ontogeny of the malleus in Mesocricetus auratus (Mammalia, Rodentia): Systematic and functional implications for the muroid middle ear

The Anatomical Record, EarlyView.
Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

The Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.
