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.
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
Breaking it down, Median would mean in the middle, ventral has something to do with the abdomen (compare ventral and dorsal, dorsal means back), and vessel would be a duct or canal. So, it would be the canal in the middle of the abdomen.
No, the ventral view is the underside or belly side of an organism, while the front side is typically referred to as the anterior side.
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.
Not always. In anatomy, superior applies to the head end and inferior to the foot end. Dorsal refers to the back, while ventral refers to the front (belly). However, in human cranial anatomy the term "superior" is applied to dorsal locations (up), while "inferior" is applied to ventral locations (down).
Ventral relates to the belly or abdomen of the frog.

You can tell cause dirt comes out the dorsal side. the dorsal side is darker because its the worms main blood vessel like our aorta
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.
dorsal
dorsal
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.
The opposite of it's dorsal. The Dorsal is the back, Ventral is the Front. Hence the dorsal fin on ocean-based organisms
The ventral side is lighter than the dorsal.
The dorsal side of an earthworm is darker than the ventral side 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 vessal, but it doesn't lie against the skin, but instead in between the ventral nerve cord and the digestive track.
