Venomous Vanguard Fact Sheet
Venomous Vanguard
A Field Guide to the Biological Classification of Toxic Serpents
Taxonomy
- Kingdom Animalia
- Phylum Chordata
- Class Reptilia
- Order Squamata
- Suborder Serpentes
While all snakes belong to the suborder Serpentes, only about 20% of the 3,000+ species worldwide are venomous.
The Major Families
Viperidae (Vipers)
Known for long, hinged fangs that fold against the roof of the mouth. This family includes pit vipers, which possess heat-sensing organs (loreal pits).
Rattlesnakes Adders Copperheads
Elapidae (Elapids)
Features short, fixed fangs at the front of the mouth. Many species in this family are highly neurotoxic, affecting the nervous system.
Cobras Mambas Sea Snakes
Colubridae (Colubrids)
The largest snake family. While most are non-venomous, some (like the Boomslang) are rear-fanged and possess potent venom.
Venom Apparatus
Modified Saliva
Venom is a complex mixture of proteins and enzymes used for immobilization and digestion.
Delivery System
Glands (modified parotid glands) connected to hollow or grooved fangs inject the toxin.
Pupil Shape
Vipers often have slit-like pupils; Elapids often have round ones.
Warning Signs
Rattles, hoods, or bright colors often signal high toxicity.
Habitat Range
Highly diverse; found on every continent except Antarctica.
