Measuring The Muscle: New Study By Scripps Researchers Depicts How The Tuna’s Body Is Built For Speed

Summary:
The mechanics of how fish use their complex muscle systems is a tantalizing puzzle in animal physiology. These muscles are the fundamental sources that fish use to power steady swimming and bursts of speed to elude predators and to capture prey. Scientists have long predicted that tuna, with their highly streamlined body and elevated internal temperatures, are equipped with a "high performance" muscle system. Tuna, researchers suspected, power their swimming by projecting muscle force from the mid-body, where the muscle is concentrated, back to the tail, which essentially acts as a natural, thrust-producing hydrofoil.
