Saguaro grows to a height of trees is 13, sometimes 15 meters. But to grow so huge cactus takes a long time: Saguaro grows very slowly. During the first 30 years, they grow no more than a meter. Then follows a period of relatively rapid growth, when the cactus adds about a millimeter a day. Only the 75 years the cactus gets its exotic appearance of a huge trunk with garlands of side chains. Living at the same cactus to 150 years, which, of course, very much for succulents.
Some species of birds, such as, for example, this little woodpecker, in the trunk of a cactus suit their nests, making their eggs and chicks are protected from predators. Nobody dares to wade through these thorns.
