摘要: Heads of the boid snakes Python sebae and molurus were dissected arthrology, myology dentition studied. Living specimens these species observed their feeding behavior analyzed by means high- regular-speed motion pictures. Camera speeds up to 400 frames per second permitted examination jaw movements during striking seizing prey. Motion picture studies conducted at regular provided information on cranial swallowing The morphology head was correlated with in an attempt analyze functional adaptive implications apparatus. The apparatus discussed terms a linkage or kinematic chain whose constrainment degrees freedom examined compared lizards. It concluded that very rigidly constrained mechanism lizards is remarkably sharp contrast loose snakes. Motions various bones particular attention given mechanical factors involved. In full protraction maxillae palatines are lifted rotated outward about longitudinal axis. These important orienting teeth respect prey related swallowing.
