Moles have been found to tolerate higher levels of carbon dioxide than other mammals, because their blood cells have a special form of hemoglobin that has a higher affinity to oxygen than other forms. In addition, moles use oxygen more effectively by reusing the exhaled air, and can survive in low-oxygen environments such as burrows. [8]
This method of lateral-stroke burrowing in shrew moles is an evolutionary adaptation due to the modification of the pectoral girdle and bones of the forelimbs. [6] The pelvic girdle is small and unmodified, but the pectoral girdle contains a special joint that causes the clavicle to join with the humerus instead of the scapula . [ 6 ]
The family Talpidae [1] (/ ˈ t æ l p ɪ d iː /) includes the true moles (as well as the shrew moles and desmans) who are small insectivorous mammals of the order Eulipotyphla. Talpids are all digging animals to various degrees: moles are completely subterranean animals; shrew moles and shrew-like moles somewhat less so; and desmans, while basically aquatic, excavate dry sleeping chambers ...
Moles are 4 to 7 inches long and have black-to-brownish-gray fur that has no grain, which allows them to move easily forward and backward in tunnels, adds Barbara Smith, consumer horticulture ...
A recent study indicates that remains of marsupial moles have been found in 5% of the cats and foxes faecal pellets examined. [19] Moles are also sensitive to changes in the availability of their food caused by changing fire regimes and the impact of herbivores. The southern marsupial mole is currently listed as endangered by the IUCN. [2]

Marsupial moles, the Notoryctidae / n oʊ t ə ˈ r ɪ k t ɪ d iː / family, are two species of highly specialized marsupial mammals that are found in the Australian interior. [2] They are small burrowing marsupials that anatomically converge on fossorial placental mammals, such as extant golden moles (Chrysochloridae) and extinct epoicotheres ().
They have tabulars in the occipital which is not found in other mammals. Their zygomatic arches form elongations of the maxillae. Their malleus is enlarged and helps in hearing under the ground. Golden moles do not have a fifth finger on their front paws. Instead, they have a huge claw on the third or second finger. Their fur has an iridescent ...
