How sloths got their sloth [PDF]
Current Biology, 2019 Summary The evolution of sloths will have to be revised after two independent molecular studies contradicted the traditional view based on morphological evidence. The two surviving genera with their distinctive arboreal lifestyles and specialised diets are also important case studies in ecology and adaptation, while their lost relatives shed light on

The Impact of ‘Selfie’ Tourism on the Behaviour and Welfare of Brown-Throated Three-Toed Sloths
Animals, 2018 The use of wild animals as photo props is prevalent across the globe and is widely recognised to represent a potential animal welfare concern. However, detailed information regarding the specific impacts of such activity on wild animal behaviour is ...

Phylogenetic analysis of 16S mitochondrial DNA data in sloths and anteaters
Genetics and Molecular Biology, 2003 We sequenced part of the 16S rRNA mitochondrial gene in 17 extant taxa of Pilosa (sloths and anteaters) and used these sequences along with GenBank sequences of both extant and extinct sloths to perform phylogenetic analysis based on parsimony, maximum ...

IV.—On the Placentation of the Sloths [PDF]
Transactions of the Royal Society of Edinburgh, 1873 Comparative Anatomists have long been desirous to obtain detailed information on the Placentation of the Sloths. The only observations on this subject which appear to have been made up to this time have been recorded by Professor Rudolphi of Berlin, and Dr C. G. Carus of Dresden.

Genetics and Molecular Biology, 2008 We sequenced 12S RNA mtDNA for the majority of the extant species of sloths and anteaters and compared our results with previous data obtained by our group using 16S RNA mtDNA in the same specimens and to GenBank sequences of the extinct giant sloth ...

Isotope data from amino acids indicate Darwin’s ground sloth was not an herbivore
Scientific Reports, 2021 Fossil sloths are regarded as obligate herbivores for reasons including peculiarities of their craniodental morphology and that all living sloths feed exclusively on plants.

EvoDevo, 2011 Background Mammals as a rule have seven cervical vertebrae, except for sloths and manatees. Bateson proposed that the change in the number of cervical vertebrae in sloths is due to homeotic transformations. A recent hypothesis proposes that the number of

A new enigmatic Late Miocene mylodontoid sloth from northern South America [PDF]
Royal Society Open Science, 2015 A new genus and species of sloth (Eionaletherium tanycnemius gen. et sp. nov.) recently collected from the Late Miocene Urumaco Formation, Venezuela (northern South America) is herein described based on a partial skeleton including associated femora and ...

Why sloths defecate on the ground: rejection of the mutualistic model
Cuadernos de investigación UNED, 2021 Introduction: Sloths are arboreal mammals that defecate on the ground, increasing the risk of predation. There are several hypotheses that try to explain why they undergo this risk.
