The molting of the skin occurs regularly in snakes. [1] Molting is common, and results in the entire outer layer of epidermis being lost. [10] In the case of snakes, it is called shedding or ecdysis. A new layer of epidermis is grown beneath the old. When it is finished, the snake secretes a fluid between the new skin and the old.
Pulmonate land gastropods are simultaneous hermaphrodites and their reproductive system is complex. It is all completely internal, except for genital protrusion (eversion) during mating. The outer opening of the reproductive system is called the "genital pore"; it is positioned on the right-hand side, very close to the head of the animal.
The hemipenis is the intromittent organ of Squamata, [4] which is the second largest order of vertebrates with over 9,000 species distributed around the world. They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate.

A common watersnake shedding its skin. Molting (or "ecdysis") serves a number of purposes - it allows old, worn skin to be replaced and can be synced to mating cycles, as with other animals. Molting occurs periodically throughout the life of a snake. Before each molt, the snake regulates its diet and seeks defensible shelter.
Just prior to shedding, the skin becomes dull and dry looking and the snake's eyes turn cloudy or blue-coloured. The old layer of skin splits near the mouth and the snake wriggles out, aided by rubbing against rough surfaces. In many cases the cast skin peels backward over the body from head to tail, in one piece like an old sock. A new, larger ...
All species in the family Typhlopidae are fossorial and feed on social fossorial invertebrates such as termites and ants. The tracheal lung is present and chambered in all species. One species, the Brahminy's blind snake, is the only unisexual snake, with the entire population being female and reproducing via parthenogenesis. [4]
Before each molt, a new button will have developed inside the last one and before the skin is shed off its body, the tip of the new button shrinks, then loosening the shell of the previous one. This process continues so the succession of molts produces an appendage consisting of a number of interlocking segments that make an audible noise when ...
