Introduction to Herpetology
What is Herpetology?
Herpetology is the branch of zoology that studies amphibians (frogs, toads, salamanders,
and caecilians) and reptiles (snakes, lizards, turtles, and crocodilians). Scientists who
specialize in this field are called herpetologists.
Why Study Herpetology?
• Biodiversity Conservation – Many reptiles and amphibians are endangered, and studying
them helps in conservation efforts.
• Ecosystem Importance – They play key roles in food chains, controlling insect populations
and serving as prey for other animals.
• Medical and Scientific Research – Their venom and skin secretions are used in medicines
and scientific studies.
Difference Between Reptiles and Amphibians
Feature Reptiles Amphibians
Skin Dry, covered with scales Moist, smooth, sometimes
slimy
Reproduction Lay eggs on land or give Lay eggs in water; young go
birth to live young through metamorphosis
Breathing Use lungs to breathe Some use lungs, others
breathe through skin
Examples Snakes, lizards, turtles, Frogs, toads, salamanders,
crocodiles caecilians
Major Groups of Reptiles and Amphibians
Reptiles
1. Snakes (Serpentes) – Legless reptiles that use their bodies to move and hunt prey.
2. Lizards (Lacertilia) – Have four legs, external ears, and can regenerate tails.
3. Turtles & Tortoises (Testudines) – Have hard shells for protection. Turtles live in water,
while tortoises live on land.
4. Crocodiles & Alligators (Crocodylia) – Large, aquatic predators with powerful jaws.
