Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Threat level and sound production mode modulate acoustic warnings and defensive biting in snakes

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Accurately assessing predation risk is important because it enables prey to match their defensive behaviours to the level of threat and avoid unnecessary investment in costly responses.

Contextually conspicuous species are more likely to be venomous: Habitat‐dependent aposematic colouration found throughout snakes

open access: yesJournal of Animal Ecology, EarlyView.
Conspicuous colouration signals venomous nature throughout snakes. Abstract Many animals use conspicuous colours to advertise their unprofitability to potential predators, a phenomenon known as aposematism. For example, conspicuous banded patterns in snakes are often highlighted as aposematic signalling of their venomous nature.
