With the exception of humans, who inhabit every continent, most primates live in tropical or subtropical regions of the Americas, Africa and Asia. They range in size from Madame Berthe's mouse lemur, which weighs only 30 g (1 oz), to the eastern gorilla, weighing over 200 kg (440 lb).ome primates (including some great apes and baboons) are primarily terrestrial rather than arboreal, but all species possess adaptations for climbing trees. Locomotion techniques used include leaping from tree to tree, walking on two or four limbs, knuckle-walking, and swinging between branches of trees (brachiation).
MDF is a very dense product and, therefore, is considerably heavier than plywood or dimension lumber. Keep this in mind when building with it. Other than this slight drawback, MDF is an excellent building material, as it accepts glue bonds very well and joins securely with nails and screws with minimal chances of fracturing. It is best to cut MDF outdoors, as it creates a lot of dust.
1 Direct exposure to water can cause MDF to swell. 2  There is no grain on MDF, as it is not a natural wood product. If this is an issue, however, it is easily remedied with veneer.  The glue present in MDF can make it hard to sink certain types of fasteners into the material.
