Gooty Sapphire Tarantula Size Top 5 Facts
The Gooty Sapphire Tarantula (Poecilotheria metallica) is a stunning and highly sought-after species in the tarantula hobby. Known for their vibrant blue and gold coloration, these arboreal spiders captivate enthusiasts worldwide. Understanding their size is crucial for proper care and appreciation. This article provides essential facts regarding the size of the Gooty Sapphire Tarantula, offering a comprehensive overview for both new and experienced keepers. These spiders are not only beautiful but also have specific requirements when it comes to their habitat and care, making the knowledge of their size essential for their wellbeing and your enjoyment of them as pets. Let’s dive into some key facts about the size of these incredible creatures.
Average Size of Gooty Sapphire Tarantulas
Generally, the Gooty Sapphire Tarantula is a medium-sized tarantula. When fully grown, adult females typically reach a leg span of about 7 to 8 inches (18 to 20 cm). This measurement is taken from the tip of one leg, across the body, to the tip of the opposite leg. Males are generally smaller than females, but this is not always a hard and fast rule; they can still grow to respectable sizes as well. Their size, though relatively modest compared to some of the larger tarantula species, still makes them a substantial presence in any terrarium. The overall size is influenced by various factors, which we will explore further in this article. This average size is a key consideration when setting up their enclosure to provide ample space and ensure the tarantula’s comfort and health.
Male vs Female Size Differences

A notable difference in size exists between male and female Gooty Sapphire Tarantulas. Females, as previously mentioned, tend to be larger and more robust. This is a common trait among tarantula species, where females invest more energy into growth and are generally longer-lived. Males, on the other hand, are typically smaller and mature faster, their primary goal being reproduction. Due to their smaller size, they also have a shorter lifespan compared to females. Males also possess other distinctive physical characteristics, such as the presence of tibial hooks on their front legs, used during mating to secure the female’s fangs. Understanding these differences is crucial for differentiating between sexes and anticipating their individual care needs. Knowing the sex of your Gooty Sapphire Tarantula helps predict its life cycle, potential longevity, and behavior patterns.
Factors Influencing Gooty Sapphire Tarantula Size
Several factors influence the ultimate size of a Gooty Sapphire Tarantula. These include genetics, diet, environmental conditions, and the care provided by the keeper. Genetics play a significant role, as certain individual tarantulas will simply be predisposed to grow larger than others. Diet is also critical; a consistent supply of appropriately sized prey items is essential for healthy growth. Similarly, maintaining optimal environmental conditions, such as proper temperature and humidity, can significantly impact the tarantula’s development. Proper enclosure size also plays a role, providing enough space for the spider to grow and molt successfully. Regular care and monitoring of these factors will assist in ensuring the tarantula’s development is on track and healthy.
Diet and Nutrition Effects
The diet of a Gooty Sapphire Tarantula greatly impacts its size and overall health. Providing a varied diet consisting of appropriately sized insects is essential. Crickets, roaches, and mealworms are common choices. The size and frequency of feedings depend on the spider’s age and growth stage. Spiderlings need more frequent meals compared to adults. Overfeeding should be avoided, as it can lead to obesity and health problems. Ensure that prey items are gut-loaded to provide the tarantula with essential nutrients. The nutritional value of the food directly affects the growth, molting, and overall wellbeing of the tarantula. A well-balanced diet supports proper development and helps achieve their maximum size potential, promoting a long and healthy life.
Genetics and Breeding

Genetic factors contribute to the ultimate size of a Gooty Sapphire Tarantula. Breeding practices can also influence these traits. Tarantulas from larger parent stock may be predisposed to grow larger themselves. Responsible breeding practices prioritize health and size, as well as the genetic diversity of the offspring. Breeders select for desired traits, which may include size and coloration. Selective breeding helps improve the overall quality of the species in the hobby, and contributes to a better experience for the keeper. The genetic makeup of the tarantula influences not only the size but also its longevity, temperament, and resistance to illness. Choosing a reputable breeder is crucial if you are looking for a healthy specimen with desirable traits.
Lifespan and Growth Rate Impact
The lifespan and growth rate of a Gooty Sapphire Tarantula have a direct impact on its size. Females, with their longer lifespans (up to 10-12 years or more), generally have more time to grow and develop, leading to larger sizes. Males, with shorter lifespans (2-3 years after maturity), have less time to reach their full potential size. The growth rate is not uniform. They grow in spurts, molting to shed their exoskeletons and increase in size. These molting cycles are crucial for growth. The rate of molting decreases as they mature. Understanding these cycles helps gauge the tarantula’s health and stage of development. Rapid growth can sometimes be a sign of overfeeding or other issues, while a slow growth rate might indicate a problem with diet, environment, or genetics.
Habitat and Environmental Conditions
Habitat and environmental conditions significantly impact the size and health of a Gooty Sapphire Tarantula. Maintaining the correct temperature (around 75-85°F or 24-29°C) and humidity levels (60-70%) is essential. Insufficient humidity can hinder molting and growth. Providing a suitable substrate, such as coco fiber, that allows for burrowing and climbing, also helps. Enclosure ventilation is also important for preventing mold and maintaining good air quality. Regular monitoring of temperature and humidity, as well as maintaining a clean enclosure, contributes significantly to the tarantula’s overall wellbeing and allows them to reach their full size potential. Creating an environment that mimics their natural habitat will lead to a happier, healthier, and larger tarantula.
Importance of Proper Enclosure Size

The size of the enclosure directly affects the Gooty Sapphire Tarantula’s ability to grow and thrive. A habitat that is too small can restrict movement, causing stress and potential health problems. While these spiders are arboreal, they require enough vertical space to climb and feel secure. The enclosure should be at least three times the tarantula’s leg span in width and length, and at least twice the leg span in height. As the tarantula grows, the enclosure should be upgraded accordingly. Providing adequate space for molting is also essential, ensuring the spider can shed its exoskeleton without difficulty. A well-sized enclosure gives the tarantula room to roam, hunt, and express natural behaviors. Choosing the appropriate size ensures that the tarantula has the space needed to reach its full size potential while also remaining healthy and content.
Gooty Sapphire Tarantula Size Comparison to Other Species
Comparing the size of the Gooty Sapphire Tarantula to other tarantula species offers a perspective on its place within the tarantula world. While impressive, they are not among the largest tarantula species. They are smaller than giants such as the Goliath Birdeater (Theraphosa blondi), which can reach leg spans of over 12 inches (30 cm). However, they are still considerably larger than many other commonly kept species, like the Curly Hair tarantula. Their size makes them more manageable for keepers, providing a balance of beauty and ease of care. Understanding the size of the Gooty Sapphire Tarantula relative to other species allows for proper planning for housing and handling. It is important to remember that each species has unique care requirements due to their size and natural behaviors.
