🍽️ Diet & Hunting Behavior

Tarantulas are carnivorous predators.

Common prey

• Insects
• Centipedes
• Small lizards

Defensive strategies

• Kicking urticating hairs (New World species)
• Threat displays
• Biting (rare)

⚠️ For most species, the venom causes pain comparable to a bee sting in humans.

🐣 Growth, Molting & Lifespan

Tarantulas grow by molting, shedding their exoskeleton.

• Molting
  • Necessary for growth
  • A highly vulnerable period
• Growth rate
  • Slow
• Lifespan
  • Females: 15–30+ years
  • Males: around 5–10 years
