simetría bilateral

simetría bilateral

Body divisibility into mirror-image halves (right and left arms and legs, for example). Animals with bilateral symmetry display dorsal (top), ventral (bottom), anterior (front), and posterior (rear) orientations, whereas radial animals like starfish have only the dorsal and ventral. (Arms, legs, and wings evolved from the fins of lungfish swimming around over 400 million years ago. )
