The twitches from the skeletal muscle that cause the rattling of the rattlesnake’s rattle is operates at one of the highest contraction frequencies sustained by vertebrate muscle. As the snake rattles at a higher frequency and higher acceleration the cost per twitch is sustained and does not increase. This is achieved by decreasing the twitch duration and reducing the horizontal displacement of the rattle joint (Moon et. Al. 2002). Muscles with these repeated, fast-paced, contractions are found to have high amounts of sarcoplasmic reticulum and mitochondrial respiration enzymes and are believed to have higher concentrations of phospholipids containing docosahexaenoic acid (22:6n-3). 22:6n-3 is believed to be required as a building component for the assembly of membrane proteins such as rhodopsin, ion pumps, and a variety of components of the mitochondrial electron transport chain (Infante et. al. 2001).
