Tarantulas are fascinating creatures, known for their large size and sometimes feared appearance. Despite their intimidating looks, they have an interesting life span that sets them apart from other spiders.
In general, the life expectancy of tarantulas largely depends on their sex. Female tarantulas can live up to 20-25 years, while males typically have a shorter lifespan of 7-8 years (. Life in the wild also presents its challenges, as tarantulas face a variety of natural predators like larger lizards, snakes, and birds.
Tarantulas spend most of their time close to their burrows, coming out mainly at night, which adds a degree of safety to their lives. Though often feared, these creatures are truly fascinating addition to the world of arachnids and provide an intriguing subject for further exploration.
So, now you know the basics of how long tarantulas typically live. Their lifespan is vastly different depending on their sex, and their natural habitat provides its own challenges and protections. With this understanding, you can appreciate these fascinating creatures from a new perspective.
Tarantula Lifespan Basics
Factors Affecting Lifespan
Tarantulas have a wide range of lifespans. The average lifespan in the wild can be up to 30 years 1. This varies by species and gender. Female tarantulas typically live longer than males. For example, a female can live 7 to 30 years, while males usually only live a few years 2.
Species
Different species of tarantulas have different lifespans. Some examples include:
- Mexican Redknee Tarantula: Females live up to 25 years; males live up to 5 years
- Chilean Rose Hair Tarantula: Females live up to 15 years; males live up to 5 years
Environmental Factors
Tarantulas need a suitable environment to thrive and reach their full lifespan potential. Factors to consider include:
- Temperature
- Humidity
- Availability of food and water
- Safe hiding spots
A well-maintained habitat can significantly impact a tarantula’s lifespan.
Here’s a comparison table for the lifespans of different types of tarantulas:
| Tarantula Species | Female Lifespan | Male Lifespan |
|---|---|---|
| Mexican Redknee | Up to 25 years | Up to 5 years |
| Chilean Rose Hair | Up to 15 years | Up to 5 years |
In conclusion, tarantula lifespans vary greatly depending on species, gender, and environmental factors. Providing the right habitat and care can help ensure a long and healthy life for these fascinating creatures.
Lifespan in Captivity vs. The Wild
Captive Care Requirements
Tarantulas can live a long time in captivity, often much longer than in the wild. Their lifespan varies depending on species, but some tarantulas can live 10 to 30 years1. Providing an appropriate environment is essential. This includes:
- A clean, secure enclosure
- Proper substrate and hiding spots
- Adequate temperature and humidity
- Access to fresh water and appropriate food
In captivity, tarantulas are less exposed to predators and harsh environmental conditions. This contributes to their extended lifespan.
Natural Habitats and Dangers
In the wild, tarantulas face multiple threats. These include changing a habitat, predators, and scarcity of food. For example, the Goliath bird-eating tarantula inhabits the rainforest regions of northern South America2. In their natural environment, they encounter various dangers such as:
- Habitat destruction due to deforestation
- Predators like birds, reptiles, and other arachnids
- Competition for resources and territory
These factors limit their lifespan in the wild, which is often shorter than in captivity.
| Factor | Captivity | The Wild |
|---|---|---|
| Lifespan | Longer | Shorter |
| Predators | Rare | Common |
| Food Availability | Consistent | Variable |
In conclusion, tarantulas in captivity generally enjoy an extended lifespan compared to their wild counterparts. Providing the proper care and environment can ensure that these fascinating creatures thrive as pets.
Different Tarantula Species and Their Lifespans
Short-Lived Species
Males of most tarantula species have shorter lifespans than females. For instance, a male tarantula from the United States typically lives about 7-8 years.
Characteristics of short-lived species:
- Mostly males
- Live 7-8 years on average
- Smaller in size
Long-Lived Species
On the other hand, female tarantulas can live much longer. Some species of female tarantulas can live for 20-25 years. The Goliath bird-eating tarantula, for example, has a leg span of up to 11 inches and is the largest tarantula species.
Characteristics of long-lived species:
- Mostly females
- Live 20-25 years on average
- Larger in size
| Features | Short-Lived Species | Long-Lived Species |
|---|---|---|
| Average Lifespan | 7-8 years | 20-25 years |
| Typical Size | Smaller | Larger |
| Gender | Mostly males | Mostly females |
In summary, tarantula lifespans vary depending on the species and gender. Males tend to have shorter lifetimes, while females live significantly longer.
Tarantula Lifespan Stages
Molting and Growing
Tarantulas experience a unique growth process called molting. During molting, tarantulas shed their exoskeleton to grow larger:
- Molting helps tarantulas replace damaged body parts and renew sensory hairs.
- Tarantulas become vulnerable during molting, hiding until their new exoskeleton hardens.
Molting frequency dwindles as tarantulas age:
- Young tarantulas molt more frequently (every few weeks).
- Adult tarantulas molt, on average, once a year.
Maturity and Reproduction
Maturity and reproduction play a vital role in tarantula lifespan. Males tend to live for 7-8 years, while females can live up to 20-25 years.
Here is a comparison table illustrating differences between male and female tarantula lifespan:
| Gender | Avg. Lifespan |
|---|---|
| Male | 7-8 years |
| Female | 20-25 years |
Mating is crucial during a tarantula’s maturity stage:
- Male tarantulas search for females, sensing them through pheromones.
- Males risk their lives during mating due to the possibility of being eaten by females.
Let’s list some key points about tarantula reproduction:
- Most species reproduce through indirect fertilization, using a sperm web and pedipalps.
- Female tarantulas lay hundreds of eggs in an egg sac shortly after fertilization.
Threats to Tarantula Lifespans
Natural Predators
Tarantulas face several natural predators that can shorten their lifetimes. Some of these predators include:
- Larger lizards
- Snakes
- Birds
One of the most ferocious predators of tarantulas is the tarantula hawk, a type of parasitic Pepsis wasp. These wasps are known for their painful sting and their ability to hunt and paralyze tarantulas.
Diseases and Parasites
Tarantulas may also suffer from diseases, infections, and parasites that can impact their lifespan. The parasitic Pepsis wasp, in particular, poses a significant threat to tarantulas as it lays its eggs in the paralyzed spider’s body. When the eggs hatch, the wasp larvae feed on the immobilized tarantula.
| Threat | Effect on Tarantula Lifespan |
|---|---|
| Natural Predators | Early death due to predation |
| Diseases and Parasites | Reduced lifespan and health issues |
Interesting Tarantula Facts
Venom and Pain
Tarantulas are known for their venom, but it’s worth noting that these creatures pose no serious danger to humans. While their venom can cause a bite to be painful, it is generally not life-threatening for human beings. Here are some quick facts about tarantula venom:
- Usually harmless to humans
- Can cause pain and discomfort
- May lead to swelling and redness
Color and Size
Tarantulas come in various colors and sizes, depending on the species. The Goliath bird-eating tarantula holds the title as the biggest tarantula in the world:
- Body up to 4.75 inches (12 centimeters)
- Leg span of up to 11 inches (28 centimeters)
On the smaller side, the Chilean rose tarantula measures:
- Females: average leg span of 5 inches (12-13 centimeters)
- Males: average leg span of 3.5 inches (9 centimeters)
Here’s a comparison table of the two species mentioned above:
| Species | Body Length | Leg Span |
|---|---|---|
| Goliath Bird-eating | Up to 4.75 inches | Up to 11 inches |
| Chilean Rose (Female) | N/A | 5 inches |
| Chilean Rose (Male) | N/A | 3.5 inches |
In terms of color, some tarantulas like the pink-toed tarantula have unique and vibrant colors. For instance:
- Marked by pink-colored toes
- Generally small in size
Other species, like the Chilean rose tarantula, might have a more subdued color palette but can still be visually striking.

Burn it!!
Why burn it? Why harm it at all? Why not move it further away from your house into some brush where it can hunt. It’s not like it is poisonous or planning to attack your family.
That comment confused me too. This is my post, and I am more excited than anything to have found this outside my front door 🙂
This is most assuredly a male tarantula; the pedipalps (those little leg-like things to either side of the mouth) are large, which is a good indicator. Additionally, close inspection of the front legs shows a bit of a “spur” on the back of the leg, immediately before one of the joints; this is used to keep females’ limbs out of the way during mating.
