🧬 Different lifespans

Animals don’t all live the same number of years.

• Some live only a few days 🐜
• Some live many years 🐘
• Some can live hundreds of years 🐢

🧠 Main reasons why some animals live longer

1️⃣ Body size

• Bigger animals usually live longer
• Smaller animals use energy very fast

🧠 Example:

• Mouse 🐭 → few years
• Elephant 🐘 → 60–70 years

2️⃣ Metabolism (how fast the body works)

• Fast metabolism → shorter life
• Slow metabolism → longer life

🧠 Tortoises have slow bodies, so they live long!

3️⃣ Protection from danger

• Animals with:
  • Shells 🐢
  • Thick skin 🦏
  • Strong armor 🦀
    are safer and live longer

4️⃣ Environment

5️⃣ Genes (body instructions)

• Some animals are born with genes that help them:
  • Repair cells
  • Fight diseases
  • Age slowly

6️⃣ Lifestyle

• Calm animals 🧘 live longer
• Animals that eat well and move slowly often age better

---
