What does it men to be bilaterally symmetrical and cephalized How might that help Dugseia in its environment?

Being bilaterally symmetrical means that an organism's body can be divided into two mirror-image halves along a central axis, while cephalization refers to the concentration of sensory organs and nerve cells at one end of the body, typically forming a head. For Dugesia, a type of planarian, these traits enhance its ability to navigate and interact with its environment efficiently. Bilateral symmetry allows for streamlined movement, while cephalization enables the organism to better detect and respond to stimuli, improving its chances of finding food and avoiding predators.
