Rotational feeding in caecilians: putting a spin on the evolution of cranial design.


Caecilians are a poorly known group of amphibians with a highly derived skull and cranial musculature that has evolved in response to their specialized head-first burrowing lifestyle. They possess a unique jaw-closing system, which is shown to be capable of generating considerable bite forces for its head width (1.09+/-0.34 and 0.62+/-0.31 N for… (More)
