Why are there coloration differences in the ventral and dorsal surfaces of the forearm and hand?
Wiki User
∙ 13y ago
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.

What are the advantages of the dark-dorsal and light-ventral colorations of the perch?
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.
