Oct 3, 2024 · We here provide a detailed description of the vertebral morphology of the African arboreal viperid snakes of the genus Atheris. Vertebrae of three different species of the genus, i.e., Atheris desaix...

Oct 3, 2024 · As the sole arboreal genus of Viperinae the prehensile nature of the tail of Atheris is reflected in its caudal vertebral morphology, which is characterized by a high number of caudal vertebrae but also robust and anteroventrally oriented pleurapophyses as a skeletal adaptation, linked with the myology of the tail, to an arboreal lifestyle.

Atheris is a genus of vipers known as bush vipers. [3] They are found only in tropical subsaharan Africa (excluding southern Africa) [2] and many species have isolated and fragmented distributions due to their confinement to rain forests. [4] Like all other vipers, they are venomous.

[3] No subspecies are currently recognized. [4] Common names include rough-scaled bush viper, spiny bush viper, [5] [3] hairy bush viper, [3] [6 ...

Oct 1, 2014 · We investigated the phylogenetic relationships and historical biogeography of the East African genus Atheris (Serpentes: Viperidae), and explored temporal and spatial relationships between Atheris species across Africa, and the impact of palaeoclimatic fluctuations and tectonic movements on cladogenesis of the genus.

Atheris squamigera uses primarily vision for communication and perception, but also makes use of tactile and olfactory senses. When threatened, it extends its body and raises the anterior portion of its body into the air, settling into a striking position.

Jun 28, 2020 · The genus Atheris, currently comprises fifteen species of small, heavily keel scaled, arboreal pit vipers. The vipers are distributed in sub Saharan African and are typically encountered in primary forest, cloud forest and disturbed forest edges.

We investigated the phylogenetic relationships and historical biogeography of the East African genus Atheris (Serpentes: Viperidae), and explored temporal and spatial relationships between Atheris species across Africa, and the impact of palaeoclimatic fluctuations and tectonic movements on cladogenesis of the genus.

Atheris hispida, the Rough-scaled Bush Viper, is a small-sized (average total length 40–60 cm, maximum total length 73.5 cm) arboreal snake with heavily keeled, spiny and leaf-shaped scales which give it a distinct appearance.
