Blind mole-rat: A common name for subterranean rodents in several genera, including Spalax. Spalax is one genus within the broader group called blind mole-rats.
Hypoxia: A condition in which tissues receive too little oxygen. Sealed burrows can become oxygen-poor, and Spalax tolerates such conditions.
Cancer resistance: The ability of an organism or tissue to avoid or suppress cancer development. Some Spalax species show unusual resistance to tumor formation, prompting biomedical study.
Bathyergidae: A family of African rodents that includes several independently evolved subterranean species. African mole-rats resemble Spalax ecologically but belong to a separate rodent family.
Spalax galili: A blind mole-rat species found in the eastern Mediterranean region. This species is among those studied for unusual tolerance of environmental stress.
Rodent: A mammal in the order Rodentia, characterized by continuously growing incisor teeth. Spalax belongs to the mammalian order Rodentia.
Hypercapnia: An abnormally high concentration of carbon dioxide in the blood or environment. Carbon dioxide can accumulate in burrows occupied by Spalax.
Tumor suppression: Biological processes that prevent cells from becoming cancerous or limit tumor growth. Cellular responses in Spalax have been investigated for mechanisms that halt abnormal growth.
Nannospalax: A genus of blind mole-rats native to southeastern Europe and western Asia. Its close taxonomic relationship to Spalax has been treated differently across classifications.
Spalax judaei: A blind mole-rat species native to parts of the eastern Mediterranean region. It provides a species-level example of the genus’s regional diversity.
