The Caenophidia are a derived clade of alethinophidian snakes, which contains over 80% of all the extant species of snakes. [1] The largest family is Colubridae, but it also includes at least seven other families, [1] at least four of which were once classified as "Colubridae" before molecular phylogenetics helped us understand their relationships.
The shape and arrangement of scales is used to identify snake species. The shape and number of scales on the head, back and belly are characteristic to family, genus and species. Scales have a nomenclature analogous to the position on the body. In "advanced" (Caenophidian) snakes, the broad belly scales and rows of dorsal scales correspond to ...
Dracaena trifasciata is a species of flowering plant in the family Asparagaceae, native to tropical West Africa from Nigeria east to the Congo. It is most commonly known as the snake plant, Saint George's sword, mother-in-law's tongue, and viper's bowstring hemp, among other names. [2] Until 2017, it was known under the synonym Sansevieria ...

Scales in the central or throat region, which are in contact with the first ventral scales of a snake's body and are flanked by the chin shields, are called gular scales. The mental groove is a longitudinal groove on the underside of the head between the large, paired chin shields and continuing between the smaller gular scales.
A snake plant in colder temperatures requires less water than in warmer temperatures, says Hancock. This is because in cooler temperatures, the plant leaves keep the stomata closed.
'Gymnophiona' derives from the Greek words γυμνος / gymnos (Ancient Greek for 'naked') and οφις / ophis (Ancient Greek for 'snake'), as the caecilians were originally thought to be related to snakes and to lack scales. [6] The study of caecilian evolution is complicated by their poor fossil record and specialized anatomy.
Additionally, in plant species that lack dimorphic sex chromosomes, dosage compensation can occur when aberrant meiotic events or mutations result in either aneuploidy or polyploidy. Genes on the affected chromosome may be upregulated or down-regulated to compensate for the change in the normal number of chromosomes present.
