Head and Sensory Organs

• Head: Usually distinct from the neck, housing important sensory organs.
• Eyes: Most have good eyesight, but some species rely more heavily on other senses.
• Jacobson’s Organ: A chemosensory organ located in the roof of the mouth, used for detecting scents.
• Heat-sensing pits: Found in some species like vipers, these pits detect infrared radiation from warm-blooded prey.

Internal Anatomy

• Digestive system: Adapted to swallow prey whole, with a highly expandable stomach.
• Muscular system: Enables powerful constriction or rapid strikes.
• Venom glands: Present in venomous species, producing toxins used for prey immobilization.

Types of Snakes

Snakes are broadly classified into two categories based on their venom and behavior: venomous and non-venomous.

Venomous Snakes

Venomous snakes possess specialized glands and fangs to inject toxins into their prey or predators. Some notable venomous snake families include:

• Viperidae (vipers and pit vipers): Characterized by triangular heads and heat-sensing pits.
• Elapidae (cobras, kraits, mambas, sea snakes): Known for their fixed front fangs and potent neurotoxic venom.

Non-Venomous Snakes

These snakes kill prey through constriction or other means. Examples include:

• Colubridae family: The largest snake family, containing many common species like garter snakes and rat snakes.
