They change colors a little once in their life: when they molt. They molt their fluffy baby fur and get a glossy adult coat when they are around 8 weeks old. Their color doesn't change much, though.
Gerbils really don't care about the color of the other gerbils in the tank with them, they really care about personality. For all we know, they could be color blind.
no!
No, not only to gerbils come in several different color varieties, but as with any animal each individual has its own personality, though with gerbils it doesn't vary as much as with say dogs.
because it is the original gerbil color, with no color mutations. it is the easiest gerbil to make.
It shouldn't it should stay the same color as it always is. A gerbil should stay the same colour when it is pregnant. My friend has two adult female gerbils and they stay the same colour.
Same reason humans have diff. colours of skin, eyes, and hair, pigmentation.
A gerbil's view of the world is much higher than this, being around 215 degrees. So the gerbil can see much more of its world at any given moment so yeah a gerbil can see they i think also can see in the dark
Other gerbils.
Gerbils are an animal and can not be "invented".
color change is when a color changes
Male gerbils can be neutered, but it is not recomended. Female gerbils should not be spayed. In general male gerbils should not be neutered unless there is a good reason for it.
* Color: Wild Mongolian gerbils have colors that help them blend in with their natural desert habitat. The dense fur on the back is a golden sandy color (agouti), and the fur on the belly is pale gray or off-white. Domestic gerbils, however, come in almost two dozen colors. Aside from their natural color, they can also be black, orange, white, deep or light gray, and nutmeg (a mix of brown, black, and orange). * Find more about gerbils: http://www.quamut.com/quamut/gerbils Please recommend me!
