Land Biomes: Savannas
Thursday May 11, 2006
Savannas are areas of open grassland with very few trees. There are two types of savannas, tropical and semi-tropical savannas.
Savannas are typically dry, receiving less than 30 inches of rain on average per year. The lack of water makes savannas a difficult place for tall plants such as trees to grow.
Many of the animals that live in savannas rely on speed for survival, as the vast open areas provide little means of escape from quick predators.
Camouflage is also very important to animals of the savanna. Both predators and prey use this technique to conceal themselves from one another.

Land Biomes
Biomes are the world's major habitats. Land biomes are identified by the vegetation and animals that populate them.
Aquatic Communities
Aquatic communities can be subdivided based on common characteristics. Two common designations are freshwater and marine communities.

Comments
Most of us are aware that animals, insects, and other living creatures can camouflage themselves. Can any creature change its color to disguise itself from prey? Is camouflage the result of the cells mutating or the cells being counsious and taking anticipatory measures over a period of years?
Not all creatures can change color to disguise themselves. Some lizards change color. Some hares can also change their fur color.
Camouflage is a result of natural selection. The animals that are camouflaged are less likely to be eaten than those that are not. Animals with this trait will reproduce and spread through the population.
