摘      要：Across the diversity of vertebrates,bite force has been studied and suggested to have important ecological and evolutionary ***,there is a notable lineage of vertebrates that use this performance trait yet are missing from the bite-force literature:the *** often rely on biting during prey subjugation and *** snakes bite and hold prey while a constriction coil is formed or while venom is being delivered,or *** use biting exclusively without employing any additional prey-handling *** addition to biting,constriction is an important predation ***,I quantify bite force and constriction pressure in kingsnakes(Lampropeltis getula).Furthermore,I explore the proximate determinants of bite force as well as the relationship between biting and constriction *** force increased linearly with all head and body *** these,head height was the best predictor of bite *** force in kingsnakes was within the range of values reported for lizards,but their relative performance was lower for their head size compared to *** constriction pressure also increased with all body *** and constricting use 2 different parts of the musculoskeletal system and are positively and significantly correlated with one *** work targeting a greater diversity of snakes that rely more heavily on biting may reveal a greater range of bite performance in this diverse and successful vertebrate group.
