Baby tarantulas, or spiderlings, are a subject of fascination for many. These tiny creatures have a captivating lifecycle, and their development from eggs to adulthood is full of surprises.
Reproduction and Birth
Tarantulas reproduce sexually, with males seeking out females to mate. The process begins when the male spins a small sperm web and deposits sperm on it. Then, he uses his pedipalps to take up the sperm and goes in search of a female.
Once he finds a receptive female, the male approaches her carefully. If she’s receptive, mating occurs, and the male quickly leaves to avoid becoming a meal, as females have been known to eat the males after mating.
After mating, the female lays hundreds of eggs, which she wraps in a silk cocoon. The eggs incubate for several weeks, and then hundreds of spiderlings emerge.

Growth and Development
Baby tarantulas go through a series of molts as they grow, shedding their exoskeleton to allow for growth. These molts are vital phases in the spiderlings’ life:
- First Instar: The spiderlings are not yet fully formed and remain in the egg sac.
- Second Instar: The spiderlings become mobile and start looking for food, though still staying close to their siblings.
- Subsequent Instars: With each molt, the spiderlings grow larger, develop more hair, and their color starts to become more defined.
After several molts, the tarantulas reach maturity, which can take anywhere from a few months to several years, depending on the species.
Behavior
Baby tarantulas display fascinating behaviors. They are generally more secretive and reclusive compared to adults. As they grow, they start to exhibit more species-specific traits, such as burrowing or creating silk-lined retreats.
Diet
Spiderlings feed on small insects like pinhead crickets, fruit flies, and other tiny invertebrates. Their diet grows with them, as they gradually shift to larger prey.

In Captivity
Raising baby tarantulas can be a rewarding hobby but requires proper care and understanding:
- Housing: Small vials or containers are suitable for housing spiderlings. Ventilation is essential, and the enclosure should have enough space for the spiderling to move but not too much to make finding food difficult.
- Feeding: Feeding spiderlings once or twice a week with appropriate-sized prey is generally sufficient.
- Molting Care: Providing a humid environment can assist in the molting process, as it can be a vulnerable time for the spiderling.
- Handling: Baby tarantulas are delicate, and handling should be kept to a minimum.
Are baby tarantulas poisonous?
Yes, baby tarantulas are indeed venomous, but it’s important to understand the distinction between being venomous and being poisonous. Venomous refers to organisms that inject venom through a bite or sting, while poisonous refers to organisms that are toxic when consumed or touched.

Venom in Baby Tarantulas
Tarantulas, regardless of their life stage, produce venom that they use to subdue their prey. The venom contains a complex mixture of proteins, peptides, and other molecules that can immobilize the prey, making it easier for the tarantula to consume.
Venom Potency in Spiderlings
The venom in baby tarantulas is generally less potent to humans than that of adults. While venom is effective against small insects and other prey, it is usually not harmful to humans. The venom’s main purpose is to immobilize prey and begin the digestion process, not to act as a defense against larger predators.
Human Reaction to Bites
Though rare, bites from baby tarantulas can occur. The reaction in humans is generally mild, often compared to a bee sting in terms of pain. Some localized swelling, redness, and discomfort at the bite site might occur but are usually short-lived.
Species Variation
It’s essential to note that the venom’s potency can vary widely between different tarantula species. Some tarantulas are known to have more potent venom that might cause more significant discomfort in humans if bitten. However, even among those species, baby tarantulas will generally have less potent venom than their adult counterparts.
Defensive Mechanism
Baby tarantulas are more likely to run and hide rather than bite if they feel threatened. Biting is usually a last resort, as their primary defense mechanism is their agility and ability to escape predators.

Do tarantulas carry eggs?
Yes, female tarantulas carry eggs, but they don’t carry them on their bodies as some insects do. Instead, a female tarantula will lay her eggs in a specially constructed silk egg sac. After mating, she will produce this egg sac, laying anywhere from 50 to 2,000 eggs (depending on the species) inside it.
She will then guard the egg sac fiercely until the eggs hatch, ensuring that it stays in an optimal environment. In some species, the female tarantula might even carry the egg sac around with her chelicerae (fangs) or attach it to her spinnerets to keep it safe from potential predators. Once the eggs hatch, the tiny spiderlings will eventually leave the mother’s vicinity to start life on their own.
So, Baby tarantulas, with their intriguing lifecycle and unique growth process, are a fascinating subject of study for both scientists and hobbyists alike. Understanding their needs and behaviors can lead to a rewarding experience in raising them, whether for observation, study or simply the appreciation of these incredible arachnids. The complexity of their early life stages stands as a testament to the wonders of nature, inviting us to look closer and learn more about the world around us.
