Robotic modeling of snake traversing large, smooth obstacles reveals stability benefits of body compliance [PDF]

open access: yesRoyal Society Open Science (2020), 7, 191192, 2020
Snakes can move through almost any terrain. Although their locomotion on flat surfaces using planar gaits is inherently stable, when snakes deform their body out of plane to traverse complex terrain, maintaining stability becomes a challenge. On trees and desert dunes, snakes grip branches or brace against depressed sand for stability.

Comparative in vitro immunoreactivity and protein analysis of Trimeresurus albolabris and Tropidolaemus wagleri venoms. [PDF]

open access: yesSci Rep
Snakebite envenomation remains a significant global health concern, with antivenoms being the primary treatment. However, variations in venom composition can affect antivenom efficacy, leading to differences in immunoreactivity.

Deep Snake for Real-Time Instance Segmentation [PDF]

open access: yesComputer Vision and Pattern Recognition, 2020
This paper introduces a novel contour-based approach named deep snake for real-time instance segmentation. Unlike some recent methods that directly regress the coordinates of the object boundary points from an image, deep snake uses a neural network to ...

Description of the antipredatory head-wobble behaviour in Chilean rear-fanged snakes Tachymenis peruviana Wiegmann, 1835 and Tachymenis chilensis coronellina Werner, 1898 (Serpentes, Dipsadidae) [PDF]

open access: yesHerpetozoa, 2022
In this work, we describe the first records of head-wobble behaviour for Tachymenis peruviana and T. chilensis coronellina. We analyse this behaviour (occurrence, frequency) and accompanying displays in both species. Of particular note is that T.
