Vivid biofluorescence discovered in the nocturnal Springhare (Pedetidae)
Scientific Reports, 2021 Biofluorescence has been detected in several nocturnal-crepuscular organisms from invertebrates to birds and mammals. Biofluorescence in mammals has been detected across the phylogeny, including the monotreme duck-billed platypus (Ornithorhyncus anatinus)

Extreme telomere length dimorphism in the Tasmanian devil and related marsupials suggests parental control of telomere length. [PDF]
PLoS ONE, 2012 Telomeres, specialised structures that protect chromosome ends, play a critical role in preserving chromosome integrity. Telomere dynamics in the Tasmanian devil (Sarcophilus harrisii) are of particular interest in light of the emergence of devil facial ...

From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy
The Anatomical Record, EarlyView.Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

Hatching time for monotreme immunology
, 2009 The sequencing of the platypus genome has spurred investigations into the characterisation of the monotreme immune response. As the mostdivergentof extant mammals, the characterisation of the monotreme immune repertoire allows us to trace the ...

Nature, 1906 IN Semon's Zoologische Forschungsreisen, Lieferung xxii. (1904), Disselhorst treats of “Die maennlichen Geschlechtsorgane der monotremen und einiger Marsupialen.” On p. 123 are two text figures, both copied from Sir Everard Home, Phil. Trans., 1802, plate xii. One represents the male genital apparatus of Echidna hystrix, the other, Fig.

Segmental composition and nerve distribution of the brachial plexus in Galictis cuja
The Anatomical Record, EarlyView.Abstract Galictis cuja is a neotropical mustelid with terrestrial locomotor habits, yet the anatomy of its brachial plexus has remained undescribed. This study characterizes the origin, organization, and distribution of the brachial plexus nerves in 15 adult specimens (30 antimeres).
