Anatomy

Prey capture in ''Hemisquilla'' species is extremely rapid. Contact with the prey is made within 4-10 milliseconds, and the striking limb moves at a linear velocity of around 10 meters per second. There are five physiologically different motor units composed of muscle fibers that work together to make this rapid strike possible.
