Distribution of Snake Fangs in the Taxonomic Tree

This is our first revision (v.1.0) of a complete snake fang taxonomy. This fang taxonomy is dynamically generated from snakeDB and always reflects the latest state of the underlying data. The aim of this page is to provide complete fang data for all snake species known to science. For this purpose we evaluated various scientific publications dealing with snake dentition.

We are not aware that there is any publication that provides fang data on species level for all snakes. Due to this, we had to use in many cases fang data mapped to higher genera like snake families. This approach does work well in some cases but it can be imprecise in others.


Here two examples about the advantages and disadvantages of asssigning fang data on family level from the book Venomous Reptiles and Their Toxins by BRYAN FRY.

A) In Plate 7 of the book FRY labeled the family Viperidae as front-fanged. Describing vipers as front-fanged is justifiable, because vipers are a extremely very well studied and comparably homogenous family of snakes. So far, there is no viper known to science that is not front-fanged. In this case, the fang mapping seems to be absolutely correct.

B) In Plate 7 of the book FRY labeled the family Colubridae as rear-fanged. Describing colubrids as rear-fanged seems an oversimplification, because colubrids are a very heterogenous family of snakes. ANDREW M. DURSO pointed out that colubrid genera like Dasypeltis, Lampropeltis, Pantherophis, Pituophis, Sonora, Regina, Atractus or Simophis may not be correctly described as rear-fanged. In this case, it seems advisable to review data for different genera or even on species level again.


In short: Even at the current state, the snakeDB fang taxonomy is the most complete data collection of its kind. But it does need future improvement as the generic data used for the first draft needs revision and verification on individual level. Please let us know if you want to contribute your knowledge and help improving the fang taxonomy. Your help will be highly appreciated!

Snake Fang Taxonomy

Color Code Legend

This taxonomic tree uses color codes on species level to display fang variation in snakes.

  • non-fanged snakes are displayed in blue font, e.g. Malayopython reticulatus
  • front-fanged snakes are displayed in red font, e.g. Naja naja
  • rear-fanged snakes are displayed in green, e.g. Rhabdophis subminiatus
  • front- & rear-fanged snakes are displayed in fuchsia, e.g. Psammodynastes pictus
  • palatine- & rear-fanged snakes are displayed in purple, e.g. Pythonodipsas carinata
  • other combinations or missing fang data is displayed in plain black
