What Are New World Tarantulas?
A Complete Guide to New World Tarantula Species
Introduction
If you’re new to the tarantula hobby, you’ve probably heard the terms “New World” and “Old World” used frequently to describe different types of tarantulas. But what does New World Tarantula actually mean?
In the tarantula hobby, New World tarantulas refer to species that are native to the Americas — specifically North, Central, and South America. These tarantulas are known for their defensive hair-flicking behavior, generally docile temperaments, and often make excellent pets for beginners and advanced keepers alike.
Key Characteristics of New World Tarantulas
✅ Geographic Origin:
- Native to the Western Hemisphere
- Countries include the USA, Mexico, Brazil, Costa Rica, Chile, Argentina, and more
✅ Defensive Mechanism:
- Possess urticating hairs — tiny, barbed bristles they can kick off their abdomen when threatened
- These hairs cause irritation to skin and eyes, making them an effective defense
- Unlike Old World species, they usually use hairs before biting
✅ Temperament:
- Many species are known for their docile and calm nature
- Great for display setups or beginner tarantula keepers
- Less aggressive compared to Old World tarantulas
✅ Venom Potency:
- Generally mild venom that is non-lethal to humans
- Bites are rare and usually only occur when the tarantula feels cornered
✅ Webbing:
- Most New World terrestrials do not produce excessive webbing
- Arboreal New World species like Avicularia or Caribena may web more
✅ Lifespan:
- Females can live 10–30+ years depending on species
- Males typically have shorter lives, especially after maturity

🏡 Terrestrial New World Tarantulas
- Examples: Grammostola, Brachypelma, Aphonopelma
- Wide, low enclosures
- Deep substrate (4–6 inches) for burrowing
- Hide, water dish, and moderate humidity
🌿 Arboreal New World Tarantulas
- Examples: Avicularia, Caribena, Psalmopoeus
- Tall, vertical enclosures with plenty of anchor points for webbing
- Higher humidity and good ventilation
- Climbing space and foliage for security
Behavior & Handling
While each species has its own personality, New World tarantulas are often:
- Slower to react defensively than Old World species
- More tolerant of mild disturbance
- Likely to flick hairs before biting (if at all)
- Better suited for educational setups, beginner enclosures, and low-risk interaction
⚠️ Note: Some species (like Nhandu or Lasiodora) may be skittish or more likely to kick hairs. Always research individual species before handling.
