Ramos do arco aórtico e da aorta torácica em bicho-preguiça (Bradypus variegatus)

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
RESUMO As preguiças são mamíferos arborícolas, bem específicos quanto aos hábitos e à morfofisiologia. Essa condição faz delas ainda mais vulneráveis aos impactos ambientais. Com o objetivo de fornecer informações que auxiliem na clínica médico-cirúrgica

Morphofunctional Space of the Forelimb in Caraguatypotherium munozi (Notoungulata; Mesotheriidae): Insights Into Wrist‐Powered Digging

Journal of Morphology, Volume 286, Issue 8, August 2025.
Caraguatypotherium munozi displays a distinctive morphofunctional configuration combining high wrist flexor leverage with reduced elbow mechanical advantage—traits consistent with wrist‐dominated scratch‐digging. Multivariate analyses place it outside the core morphospaces of extant locomotor groups.

Morphological aspects of placenta of the Bradypus variegatus Shinz, 1825

Brazilian Journal of Veterinary Research and Animal Science, 2003
The morphological aspects of the placenta and fetal membranes were investigated in 03 sloth originated from the forestal zone in the state of Pernambuco, Brazil. These structures were obtained in 03 pregnant females from Universidade Federal de Pernambuco, two of them were frozen and the third placenta was collected by caesarian, and mother and fetus ...

Three‐Dimensional Limb Kinematics in Brown‐Throated Three‐Toed Sloths (Bradypus variegatus) During Suspensory Quadrupedal Locomotion

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 5, Page 564-577, June 2025.
ABSTRACT Suspensory locomotion differs significantly from upright quadrupedal locomotion in mammals. Nevertheless, we know little concerning joint kinematics of suspensory movement. Here, we report three‐dimensional kinematic data during locomotion in brown‐throated three‐toed sloths (Bradypus variegatus). Individuals were recorded with four calibrated

The tracks of the megaterium. Anatomical comparision between Eremotherium Rusconii and Bradypus Variegatus

Acta Biológica Colombiana, 2004
Based on an anatomical comparison between Eremotherium rusconii and Bradypus variegatus and a literature review, similarities and differences between these species were established in an attempt to explain the extinction of E. rusconii.

Hand-Rearing and Weaning of a Bradypus Variegatus Cub

International Journal of Zoology and Animal Biology, 2022
In the first days of life, Bradypus variegatus cubs already consume leaves and buds offered by the mother, concomitantly with breastfeeding. After 30 days, they start weaning and initiate a strictly folivorous diet.

How much seagrass does a dugong need? Metabolic rate of live wild dugongs, Dugong dugon, determined through indirect calorimetry (oxygen consumption)

Marine Mammal Science, Volume 41, Issue 2, April 2025.
Abstract Deterioration of seagrass beds worldwide has raised concern about the future of dugongs because almost all aspects of their life history depend on availability of seagrass. Understanding their energy metabolism and consequently how much seagrass they need will inform protective conservation strategies for dugongs. This study determined resting
