What is a Tarantula
Tarantulas are large, hairy spiders belonging to the Theraphosidae family. They are known for their size, with some species having leg spans exceeding 10 inches. Unlike many spiders, tarantulas are relatively long-lived, with females capable of living for over 20 years in some cases. They are found in various habitats, from rainforests to deserts, across the globe. Their diverse appearances range in color from brown and black to vibrant blues and oranges, adding to their intrigue. They are primarily nocturnal hunters, using venom to subdue their prey, which includes insects, small reptiles, and even rodents. Their existence is a testament to the intricate and diverse ecosystem they inhabit.
Habitat and Range

Tarantulas are found in a wide range of habitats, primarily in tropical and subtropical regions around the world. Their geographical distribution spans across the Americas, Africa, Asia, and Australia. They have adapted to diverse environments, including rainforests, grasslands, deserts, and even burrows in the ground. The specific habitat of a tarantula species depends on its type. Some tarantulas are arboreal, meaning they live in trees, while others are terrestrial, residing on the ground. Their ability to thrive in various environments speaks to their resilience. The Marwell Zoo exhibit seeks to replicate these natural habitats as closely as possible, ensuring that the tarantulas are comfortable and that visitors can observe their natural behaviors.
Marwell Zoo Tarantula Facts Number 1: Size and Appearance
One of the most striking features of tarantulas is their size and diverse appearances. These spiders range in size, with some species having leg spans that can reach over 10 inches, making them some of the largest spiders in the world. Their bodies are covered in dense hairs, which vary in color and texture depending on the species. These hairs can range from subtle browns and blacks to vibrant hues of blues, oranges, and reds. The different coloration and hair patterns serve various purposes, including camouflage, attracting mates, and possibly regulating body temperature. At Marwell Zoo, visitors have the opportunity to observe these variations, learning about the different species and their unique physical characteristics. The size and appearance are some of the first things to grab anyone’s attention.
Marwell Zoo Tarantula Facts Number 2: Diet and Feeding Habits
Tarantulas are carnivorous predators, primarily feeding on insects and other invertebrates. However, depending on the species and size, they may also prey on small vertebrates such as lizards, rodents, and birds. They are nocturnal hunters, often ambushing their prey or actively stalking them. Their fangs are used to inject venom, which paralyzes the prey and begins the digestive process. Once the prey is subdued, the tarantula will inject digestive enzymes, liquefying the internal organs before consuming the meal. The feeding habits of tarantulas at Marwell Zoo are carefully managed to ensure they receive a balanced diet appropriate for their species. This aspect of their behavior is a core part of understanding their survival.
Marwell Zoo Tarantula Facts Number 3: Venom and Defense Mechanisms

While tarantulas are venomous, their venom is generally not considered life-threatening to humans. The venom is primarily used to subdue prey, causing paralysis. For humans, a tarantula bite may cause pain, redness, and swelling, but serious reactions are rare. In addition to venom, tarantulas have other defense mechanisms, such as flicking urticating hairs (tiny barbed hairs) from their abdomen. These hairs can irritate the skin and eyes of potential predators. At Marwell Zoo, staff handle tarantulas with care and follow strict safety protocols to minimize the risk of bites or irritation. Visitors are educated about the importance of respecting the animals and not handling them.
Marwell Zoo Tarantula Facts Number 4: Lifespan and Reproduction
Tarantulas are known for their relatively long lifespans, especially the females. Some species can live for over 20 years in captivity, while males typically have shorter lifespans. Reproduction in tarantulas involves a mating process, where the male uses specialized pedipalps (small appendages near the mouth) to transfer sperm to the female. The female then lays eggs in a silken sac, which she guards until the spiderlings hatch. The spiderlings undergo several molts as they grow, shedding their exoskeleton to accommodate their increasing size. The lifecycle of tarantulas at Marwell Zoo is carefully monitored, providing insight into their development and reproductive behavior. This information is critical for preserving their population.
Marwell Zoo Tarantula Facts Number 5: Conservation Status
While many tarantula species are not currently listed as endangered, some are threatened by habitat loss, deforestation, and the pet trade. Conservation efforts are crucial to protect these fascinating creatures and their habitats. Marwell Zoo plays a role in these efforts through education, research, and potentially participating in breeding programs. By educating visitors about the importance of tarantula conservation, Marwell Zoo helps raise awareness about the challenges these animals face. The zoo’s commitment to conservation underscores its mission to protect biodiversity and inspire a passion for wildlife. Support of organizations like Marwell Zoo can help with species’ preservation.
