The space in the thoracic cavity between the concave inner surfaces of the lungs, in which (in a special pericardial cavity) the heart is located, is called the mediastinum. The thoracic cavity is lined with a serous membrane called the pleura. The lungs are enclosed in the so-called pleural cavities, which are separate in man but communicate with one another in the majority of mammals. The shape of the thoracic cavity depends upon the shape of the thorax and the position of the diaphragm.
We sell 5 hammock sizes on the Traditional Hammocks (no spreader wood bars). Therefore, the length of the hammock is the same for each size but the difference is the width. Width gives the size. The larger the size, the wider and bigger the hammock.
Everyone loves the floppy ears of the Nubian but standard Nubians get SOOOOO big! (many get well over 200 lbs while most MiniNubians are close to 100# or less). The MiniNubians are smaller than the Nubian but larger than the Nigerian Dwarf. Our does average around 24-26 inches at the withers (shoulder). Their smaller size makes them a lot easier to handle than their larger relatives, so hoof trimming, clipping, showing and milking become much easier.
