The dorsal side of a biped is it's back and the ventral side is the abdomen.
The opposite of it's dorsal. The Dorsal is the back, Ventral is the Front. Hence the dorsal fin on ocean-based organisms
Bilateral symmetry
Frogs usually have a dark green or brown dorsal color and a white or yellowish ventral color. This helps them blend in with the water surface from above and the water surface from below as well giving protection from underwater and above water predators.
dorsal
The 'dorsal-fin' extends upward from the back of organisms; so anything Ventral must reside near to an organism's front-side.
dorsal
Upper part darker, can see venation more clearly. Upper part (ventral) originates from xylem. Lower part (dorsal) originates from phloem. Do not confuse with other denominations of dorsal/ventral.
The ventral side is lighter than the dorsal.
Dorsal and ventral roots are a feature of spinal nerves only. Cranial nerves do not have dorsal and ventral roots.
There is frequently different coloration between the ventral and dorsal surfaces of many parts of the body. Coloration differences may be due to the different degree of sunlight protection that the two surfaces require. The dorsal surface is normally exposed to more sunlight... and damaging rays. It may also be a sort of communication tool as well, since exact posture and attitude is more visible with color or cast distinctions between the two surfaces.
