The mantle is the layer below the crust. It makes up almost two thirds of the earth's mass and is about 2900 km thick. The mantel is divided into two regions, the upper and lower sections.Directly below the upper section is the asthenosphere.he thin, outermost layer of the earth is called the crust. It makes up only one percent of the earth's mass. The continental crust is thicker than the oceanic crust. It can range from 25 km thick at the edges to 70 km thick near the center.
The family Phylliidae (often misspelled Phyllidae) contains the extant true leaf insects or walking leaves, which include some of the most remarkably camouflaged leaf mimics in the entire animal kingdom.They occur from South Asia through Southeast Asia to Australia.hey do this so accurately that predators often are not able to distinguish them from real leaves.

To further confuse predators, when the leaf insect walks, it rocks back and forth, to mimic a real leaf being blown by the wind.
