Streptaxid
Streptaxidae is a family (biology), family of carnivorous air-breathing land snails, terrestrial molluscs, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora. Six Streptaxidae subfamilies are accepted in the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), 2005 taxonomy of the Gastropoda by Bouchet & Rocroi. Streptaxidae are carnivorous except for one species ''Edentulina moreleti'', which is herbivorous. All streptaxids have well-developed radula, except ''Careoradula perelegans'', which is the only known terrestrial gastropod without radula. Altogether 66 species from the family Streptaxidae are listed in the 2010 ''IUCN Red List''. Distribution The historical area of origin of the Streptaxidae is probably Gondwanaland.Gerlach J. & Adolph Cornelis van Bruggen, Bruggen A. C. van (1999).

Radula
The radula (, ; plural radulae or radulas) is an anatomical structure used by molluscs for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus. The radula is unique to the molluscs, and is found in every class of mollusc except the bivalves, which instead use cilia, waving filaments that bring minute organisms to the mouth. Within the gastropods, the radula is used in feeding by both herbivorous and carnivorous snails and slugs. The arrangement of teeth ( denticles) on the radular ribbon varies considerably from one group to another. In most of the more ancient lineages of gastropods, the radula is used to graze, by scraping diatoms and other microscopic algae off rock surfaces and other substrates. Predatory marine snails such as the Naticidae use the radula plus an acidic secretion to bore through the shell of other molluscs. Other predatory marine sn ...

Gondwanaland
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Panga ...
