The dorsal side of an earthworm is darker than the ventral side. This is because of the dorsal blood vessal that runs along the top of the digestive track and just under the skin. There is a ventral blood vessel, but it doesn't lie against the skin, but instead in between the ventral nerve cord and the digestive track.
Yes. Ventral can mean closer to the abdomen, below or the bottom surface of an object such as ventral surface of the tongue (bottom side).
The upper side of a leaf is referred to as the dorsal side. It is also known as the adaxial surface and is typically darker in color compared to the lower side, which is called the ventral side or abaxial surface.
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.
Ventral is the belly side. Dorsal is the back. ventral also known as the anterior surface
Caudal Surface
The dorsal surface of the arm refers to the back or posterior side of the arm. It is opposite to the ventral surface, which is the front or anterior side of the arm.
the dorsal is along the back and is darker from the main blood stream, where as the ventral is along the front and is very light from the less blood in the certain vessel....so yeah

Simply put, it's the "bacK". The belly side is "ventral", the upper or back side is "dorsal".
dorsal
Ventral refers to the belly side or front of an organism, while dorsal refers to the back or upper side. These terms are commonly used to describe the positioning of structures or features on an organism.
It helps them camouflage itself from predators. Although the answer above is true, here is a more informative answer. The bottom of the frog is a lighter color then the top. This is because if the frog is floating on top of the water, and prey or a predator looks up and the frog, the suns glare makes the frog harder to see. Also, there are darker splotches on the bottom so it doesn't show the silhouette for the frog. the top of the frog is darker because when swimming at the bottom of a murky lake, it blends in with the bottom.
