We all know that the Texas Bluebonnets seeds look like pebbles so that the birds will think they are the pebbles that they need to help them digest...... can you name a plant that resembles a pebble, stone or rock to survive?
Spoiler Lithops or Living stones. They're called living stones because in their natural habitat they have evolved to mimic the stones and pebbles which often litter the ground where they grow. As stones can be different colours, so are Lithops. The hues and patterns produced by these plants is astonishing. The reason they have developed this ability to look like stones is really very obvious. There are many small mammals which share the same arid habitat as Lithops - animals which would be only too glad to bite into the juicy leaf of a succulent and quench their thirst on the abundant liquid therein. The thick skin of the top of a Lithops leaf is also a deterrent to most insects.
Spoiler From the south of the African continent and the family Aizoaceae this succulent plant blends in with surrounding rocks to avoid being eaten. With the common name of pebble plant or living plant the Lithops leaves are not green but are shades of cream, grey and brown with darker windowed areas, dots, and red lines, an apt disguise for a plant among rocks.
