Appearance of the Blue-Toed Tarantula
Size and Colors

Blue-Toed Tarantulas are medium-sized tarantulas, with females typically reaching a leg span of about 5-6 inches, while males are slightly smaller. Their overall coloration is a deep, velvety black or dark brown. What truly sets them apart, of course, are their namesake blue feet. The vibrant blue coloration on their tarsi (the tips of their legs) provides a stunning contrast to their dark bodies. This striking color combination makes them a visually appealing pet, attracting many reptile and invertebrate hobbyists. The intensity of the blue can vary from individual to individual, with factors such as genetics and diet potentially influencing the shade.
Unique Blue Feet
The most distinctive feature of the Blue-Toed Tarantula is undoubtedly its vibrant blue feet. This unique coloration serves no known specific function, but it is thought to be a form of aposematism, a warning signal to potential predators. The bright blue color is caused by pigment present in their exoskeleton. As they molt, the blue color will be refreshed. This helps to identify them and avoid any potential harm. The blue feet are a great visual for these tarantulas. They add beauty and make them a favorite choice for spider enthusiasts.
Habitat and Distribution
Where Do Blue-Toed Tarantulas Live?

Blue-Toed Tarantulas are native to the tropical rainforests of Guyana and Venezuela in South America. They are arboreal, meaning they live primarily in trees. They can be found in various habitats, including tree trunks, foliage, and crevices. Their natural habitat is characterized by high humidity and warm temperatures. These spiders have adapted to the conditions. Their habitat gives clues on how to keep them in captivity. You can replicate similar environments for the tarantula. Understanding their natural environment is crucial to providing them with a suitable environment in captivity.
Ideal Climate and Environment
In their natural environment, Blue-Toed Tarantulas thrive in a humid and warm environment. The high humidity is essential for their health and molting process. The temperature should typically range from 75 to 85 degrees Fahrenheit. They seek shelter in the foliage, tree bark, or crevices to regulate their body temperature and humidity. Replicating these conditions in captivity is crucial for their well-being. This includes providing a proper substrate, water, and temperature. The proper climate will help them survive and thrive. It is important to provide a habitat that mimics their natural environment to ensure they remain healthy and active.
Top 5 Facts About Blue-Toed Tarantulas
Fact 1 Arboreal Lifestyle

The Blue-Toed Tarantula’s arboreal lifestyle is a defining characteristic. Unlike many other tarantula species that are terrestrial (ground-dwelling), Blue-Toed Tarantulas spend most of their time in trees. This preference significantly influences their behavior and the setup required for their enclosure. They are agile climbers, using their claws and the hairs on their legs to grip the bark and leaves. They build webs in trees. This web acts as a trap to catch their prey. Understanding their arboreal nature helps in providing a suitable enclosure with vertical space and climbing opportunities, promoting their natural behavior and well-being.
Fact 2 Diet of Insects
Blue-Toed Tarantulas are carnivores that primarily feed on insects. Their diet in the wild consists of whatever insects they can catch. They have a high metabolism. They need to feed frequently. Crickets, roaches, mealworms, and other readily available insects are appropriate for feeding. You should vary the diet. This is to ensure that they get all the necessary nutrients. The size of the prey should be appropriate for the tarantula’s size; it should be no larger than the tarantula’s body. Proper feeding is critical for their growth and health, contributing to their longevity and overall well-being.
Fact 3 Lifespan and Growth
Blue-Toed Tarantulas have a relatively long lifespan. Females can live for 10-15 years or longer with proper care, while males typically have a shorter lifespan of 3-5 years. Their growth is influenced by several factors, including their diet and environment. Tarantulas grow through molting. As they get larger, they shed their exoskeleton. During molting, they are very vulnerable. It is crucial to provide a safe environment. Their growth rate varies. It depends on their age, how much they eat, and the conditions of their habitat. The lifespan and growth patterns are important aspects for any pet owner.
Fact 4 Venom and Handling

Blue-Toed Tarantulas, like all tarantulas, possess venom. Their venom is not considered medically significant to humans. The bite can cause some discomfort and local swelling. However, the severity of the reaction varies. Most people experience mild symptoms. They are generally docile species. They are unlikely to bite unless they feel threatened. Handling these tarantulas is not recommended. If handling is necessary, it should be done with extreme care. Avoid sudden movements. Ensure the tarantula feels secure. It is important to be cautious around this species to prevent bites.
Fact 5 Molting Process
Molting is a natural process where tarantulas shed their exoskeleton to grow. During this time, the Blue-Toed Tarantula will become very vulnerable. Before molting, they often stop eating. They may spend a lot of time in their burrow. The molting process can last from a few hours to a few days. Do not disturb the tarantula during molting. Provide high humidity and a safe environment. After molting, the tarantula’s new exoskeleton will be soft. The tarantula will have an increased appetite as it recovers. This process is critical for their growth and health. Proper care during molting ensures that the tarantula will thrive.
Caring for Your Blue-Toed Tarantula
Creating the Perfect Enclosure

The enclosure should be tall rather than wide. This is because they are arboreal. A suitable enclosure size for an adult Blue-Toed Tarantula is around 12x12x18 inches or larger. The enclosure should provide plenty of vertical space. It should have climbing opportunities, such as cork bark, branches, and artificial plants. The enclosure must have a secure lid to prevent escapes. The enclosure should be well-ventilated. This ensures the exchange of air while maintaining proper humidity. The right enclosure will help the tarantula to stay safe.
Substrate and Decorations
The substrate should retain moisture to help maintain the proper humidity levels. Good options include a mix of peat moss, coconut fiber, and vermiculite. Provide a layer of 3-4 inches of substrate. This encourages burrowing. The enclosure can be decorated with cork bark, branches, and artificial or live plants. These provide hiding places, climbing areas, and a more natural environment. Decorations also make the enclosure more visually appealing. Decorations should be secure. They also must not pose a risk of injury or entrapment to the tarantula.
Temperature and Humidity
Maintaining the correct temperature and humidity levels is crucial for your Blue-Toed Tarantula’s well-being. The ideal temperature range is between 75-85°F (24-29°C). This can be achieved using a heat lamp or a heat mat. Always ensure the heat source is regulated by a thermostat to prevent overheating. Humidity levels should be kept between 70-80%. This is best measured with a hygrometer. You can maintain humidity by misting the enclosure regularly, especially the substrate. A shallow water dish should always be available. This provides a constant source of moisture and helps to increase humidity levels.
Feeding and Watering

Feeding your Blue-Toed Tarantula is a straightforward process. They primarily eat insects. Feed them crickets, roaches, or mealworms. The prey items should be no larger than the tarantula’s body. Feed juveniles 2-3 times a week. Feed adults 1-2 times a week. Always remove any uneaten prey within 24 hours to prevent stress or injury to your tarantula. A shallow water dish should always be available. This should have clean water. The dish should be filled regularly. Water is essential for hydration and the molting process.
Handling and Safety
Handling Blue-Toed Tarantulas is not generally recommended, as it can stress them and increase the risk of a bite. If handling is necessary for any reason, do it cautiously. Approach the tarantula slowly. Avoid making sudden movements. Do not force the tarantula to do anything it doesn’t want to do. If a bite occurs, wash the area with soap and water. Monitor the bite for any signs of an allergic reaction. Always supervise children around tarantulas. Make sure to thoroughly wash your hands before and after handling the enclosure or anything inside. This helps maintain hygiene.
Conclusion
The Blue-Toed Tarantula is a fascinating and rewarding pet for those prepared to provide the right care. By understanding their unique needs and behavior, you can create a thriving environment that allows your tarantula to flourish. From its striking appearance to its arboreal lifestyle, the Blue-Toed Tarantula is a captivating creature. With the right setup, a balanced diet, and responsible handling practices, you can enjoy the beauty and wonder of these amazing arachnids for years to come.
