Tarantulas are often misunderstood due to their intimidating appearance and fearsome reputation. However, these eight-legged creatures are incredibly fascinating. Here are ten surprising facts about tarantulas that might change the way you view these spiders.
1. Tarantulas Have a Diverse Diet
While many people think tarantulas only eat insects, their diet is actually quite varied. In the wild, they may consume small vertebrates like frogs, lizards, and even small birds. Larger tarantula species can prey on animals up to half their body size. In captivity, their diet usually consists of crickets, mealworms, and sometimes pinkie mice or other small rodents.
2. The Potency of Tarantula Venom Varies
Not all tarantula venom is equally potent. The venom’s strength can differ significantly among species. For example, the venom of the Brazilian wandering spider can cause severe pain and symptoms similar to a severe allergic reaction, while many tarantulas have venom that causes only mild irritation or redness in humans. Their venom primarily helps them subdue their prey rather than defend against predators.
3. Female Tarantulas Have Remarkable Lifespans
Tarantulas can have surprisingly long lifespans. Female tarantulas can live up to 20 years or more in captivity, whereas males generally live only 5 to 10 years. This difference is due to the males’ increased exposure to risks during their search for mates, which often shortens their life expectancy.
4. Tarantulas Have Specialized Sensory Hairs
Tarantulas possess trichobothria, specialized sensory hairs on their legs and bodies that help them detect their surroundings. These hairs are highly sensitive to vibrations and air currents, allowing tarantulas to sense prey and predators even in low-light conditions or when hidden in burrows.
5. Tarantulas Use Urticating Hairs for Defense
When threatened, tarantulas have a unique defense mechanism. They can rub specialized urticating hairs on their abdomen against their exoskeleton to release tiny, irritating hairs into the air. These hairs can cause itching and irritation in potential predators, serving as a deterrent. Tarantulas may also use their fangs to bite if necessary.
6. Tarantulas Molt to Grow
Tarantulas grow by molting, a process where they shed their old exoskeleton and emerge with a new, larger one. This process can take several hours, during which the tarantula is vulnerable and often hides until its new exoskeleton hardens. Younger tarantulas may molt more frequently than older ones.
7. Tarantulas Display a Variety of Colors and Patterns
Tarantulas come in a wide range of colors and patterns, from vibrant blues and greens to more muted browns and blacks. These colors can serve various purposes, such as camouflage or warning coloration. For example, the cobalt blue tarantula (Ceratogyrus marshalli) uses its bright colors to signal potential danger to predators.
8. Tarantulas Have Elaborate Mating Rituals
Tarantula mating involves intricate courtship rituals. Male tarantulas perform a courtship dance that includes leg movements and vibrations to attract females. This display is intended to demonstrate their suitability as mates. Males must be cautious, as females can sometimes be aggressive and may attack if they feel threatened.
9. Many Tarantulas Are Burrow Builders
Tarantulas often create complex burrows to live in. These burrows provide protection from predators and environmental conditions. Some species, like those from the genus Aphonopelma, dig deep and elaborate burrows that can extend several feet underground. The design of these burrows depends on the species and their habitat.
10. Tarantulas Play an Important Ecological Role
Tarantulas contribute significantly to their ecosystems. As predators, they help control insect populations, and they also serve as prey for larger animals. Their presence can indicate the health of their environment, and by maintaining insect population balance, they play a key role in their ecological niche.
