The body of the tuna is spindle-shaped, resembling a torpedo.The scales have degenerated into small round scales, suitable for rapid swimming with a top speed of 20 meters per second.As the tuna must constantly maintain high-speed swimming to sustain its body's supply, and given that it only inhabits deep sea areas, its flesh is tender, fresh, free from pollution, and a rare healthy delicacy.Fresh tuna has always been a premium in seafood cuisine.
