Strike kinematics in death adders: convergence with vipers?(Collegiate Communications--Undergraduate)(prey capture behavior of Elapids)
|
Death adders (Acanthophis) are terrestrial elapids who superficially resemble vipers. They are ambush hunters with large, triangular heads, slender necks, and stout bodies (1). Elapids and vipers differ significantly in cranial musculoskeletal morphology. Differences relating to prey capture kinematics exist mainly in maxillary morphology and relationships, palato-pterygoid bar connections, and the dorsal constrictor muscles (2-5). Vipers, even though they are basal colubroids, are considered to have the most optimized prey capture apparatus, whereas elapids are less modified ...
