How Big Can A Tarantula Get: Tarantula Size

What Determines the Size of a Tarantula?

How big can a Tarantula get so the answer is Tarantulas are known for their large size, but not all species grow to the same dimensions. The size of a tarantula is determined by a combination of factors, including species, habitat, and diet. Some species naturally grow larger due to their genetic makeup, while others may remain smaller.

  • Species: Different tarantula species have different growth potentials. For example, the Goliath Birdeater is renowned as the largest tarantula species, capable of growing up to 12 inches in leg span.
  • Habitat: The environment in which a tarantula lives plays a crucial role in its growth. Tarantulas from tropical rainforests tend to grow larger due to the abundance of food and favorable conditions.
  • Diet: A tarantula’s diet, rich in protein, supports its growth. Larger tarantulas often feed on birds, rodents, and other small animals, allowing them to reach impressive sizes.

How Do Tarantulas Grow?

Tarantulas grow through a process called molting. Molting is when a tarantula sheds its exoskeleton to grow larger. This process happens multiple times throughout a tarantula’s life, especially during its younger years.

  • Molting Frequency: Younger tarantulas molt more frequently than adults. A young tarantula may molt several times a year, while an adult may molt only once or twice annually.
  • Size Increase: Each molt allows the tarantula to grow significantly in size. After molting, a tarantula’s new exoskeleton is soft, making it vulnerable for a short period. However, it hardens quickly, allowing the tarantula to resume normal activities.
