the advantage is that so they can see when they are dark and light.
im hungry.. make me a sandwich.
kthxbye
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
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.
A frog is split into two colors. The top portion (dorsal) is dark so it can avoid predators looking for an easy meal. The bottom portion (ventral) is light so it can find food without being spotted.
It is a camoflauge technique to hide from either predator or prey - from above, the dark dorsal makes it harder to see against the background of the dark depths; from below, the light ventral makes it harder to see against the lighter back ground of sunlit waters. For obvious reasons, this skin coloration is only seen on organisms living in the euphotic zone.
greenAnother AnswerA green sea turtle is a dark green on the dorsal side (back) and a light cream or white color on the ventral side (bottom).
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.
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.
The advantage is that black eye will absorb the light instead of reflecting it. Black absorbs light and white reflects all off it
The ventral spinothalamic tract carries "light touch" sensation. There are three neurons that carry the information to the brain. From the cutaneous nerve(s) in the skin to the dorsal root ganglia, then to the dorsal horn in spinal cord, crossing over to the other side and traveling up to the thalamus, and finally from the thalamus to post-central gyrus. Because the axons of the neuron cross over to the other side of the spinal cord almost immediately, a spinal cord lesion will produce loss of this sensation on the opposite side of the body below where the lesion occurs. According to one of my medical books, however, light touch can ALSO be carried via the medial lemniscus tract, which doesn't cross until it reaches the brain stem. That being true, light touch could be spared even if there is damage to the ventral spinothalamic tract. I hope that helps! Compliments of your friendly MSI :)
In a way, yes. Animals only spawn in light, so it gives the effect of them being attracted. They do also follow light, use to advantage.
The upper side of an organism is its dorsal side. This side typically faces away from the ground or substrate and is often more exposed to light and the environment.
This is one of nature's most common camouflage methods for creatures that live in, or spend a lot of time in, the water. When viewed from below, they blend into the (lighter) sky. When viewed from above, they blend into the (darker) bottom of the pond or lake. Most fish also have this color arrangement.
