Snake fangs work like hypodermic needles. When a snake bites its prey, or you, muscles inside the snake’s head contract to squeeze the venom glands. This pushes the liquid venom through the fangs and into the flesh. Some snakes, like large rattlesnakes, have a large amount of venom in their fangs.
Venomous fangs first developed as grooves at the base of snakes' teeth. These grooves most likely evolved to keep teeth firmly attached to the jaw, as snake teeth typically have very...
We examined the 3D shape of fangs from 81 snake species belonging to four families, with the exception of the rare atractaspidids. By measuring differences in the strength and sharpness of the fangs, we were able to show how fang shape is closely tied to prey preference.
An 'evo-devo' study of venomous snakes has arrived at a new model for the evolution of snake fangs, a subject of some controversy. Many of the advanced snakes alive today use syringe-like fangs...
Biologists have sunk their teeth into the question of snake fang development, revealing how these poison prickers have evolved from regular teeth and allowed snakes to become such champion...
These needle-like teeth are used by snakes to pierce their prey and inject deadly venom. With more than 3000 species of snake inhabiting our world, we wondered: are all their fangs the same?
We examined the three-dimensional shape of fangs from 81 snake species belonging to four families, with the exception of the rare atractaspidids.
The new study by Vonk is the first in decades to compare how front and back fangs develop within snake embryos. As snake embryos develop within eggs, their cells multiply and differentiate.
Venomous snakes inject a cocktail of toxins using venom fangs — specialised teeth with grooves or canals running through them to guide the venom into a bite wound. Uniquely among animals,...
Venomous snakes—the pinnacle of snake evolution—are characterized by their possession of venom-conducting fangs ranging from grooved phenotypes characterizing multiple lineages of rear-fanged taxa to tubular phenotypes present in elapids, viperids and atractaspidines.
