Meet the ivory ornamental tarantula! This unique spider loves to climb trees in Sri Lanka. With a quick pounce, they catch their food. Join us to discover cool facts about this amazing tree-loving spider!
Color: Male: They are pale brown, both on the dorsal and ventral sides. All four leg pairs appear metallic brown. Female: They have a more striking appearance, resembling a starburst. The carapace is dark brown with pale edges and a set of cream-colored mouthparts. The legs are similar, made up of segments alternating in cream and black parts.
Other Characteristic Features: The females tend to be much larger than the males.
Eggs
The eggs of this tarantula are bright orange.
Spiderlings
The spiderlings are brown and covered with setae. After maturing, they will start resembling the adults.
The Web
They create an asymmetrical tunnel web, visible only at night.
Are Ivory Ornamental Tarantulas Venomous?
Yes, Ivory Ornamental tarantulas have venom. It is quite potent, causing severe localized damage if injected via a bite.
Can Ivory Ornamental Tarantulas Bite?
Ivory Ornamental tarantulas are incredibly agile and capable of delivering a nasty bite. They might bite if they feel cornered, but they’re mostly focused on their tree-climbing and hunting.
Ecological Importance and Behavior of Ivory Ornamental Tarantula
As a crucial component of their ecosystem, the ivory ornamental tarantula helps maintain insect populations. Their nocturnal tree-climbing hunts showcase their role as both predator and prey within the forest’s food web.
Natural Predators: Despite their venom, these tarantulas are not without threats. Birds of prey and larger reptiles often prey on them, maintaining the delicate balance of the ecological hierarchy.
Prey-Predator Dynamics: Their diet comprises various insects, making them essential in regulating insect abundance and preventing overpopulation, which could otherwise lead to crop damage and spread of disease.
Relationship with Humans: Humans rarely encounter ivory ornamental tarantulas, and their venom, though potent, is not lethal to humans. In fact, their presence signifies a healthy, undisturbed habitat, critical for biodiversity conservation.

Did You Know
It is often classified separately – Poecilotheria uniformis (highland ivory ornamental tarantula) and Poecilotheria bara (lowland ivory ornamental tarantula). The two can be distinguished from the markings on their abdomens, with the lowland variant having an incomplete pattern instead of the more completed pattern on the highland variant.
These tarantulas have a mutualistic relationship with certain frogs like Nagao’s pug-snout frog. The spider protects the frog from predators, while the frog keeps ants away from the spider’s eggs.
In summary, the ivory ornamental tarantula is a key player in its ecosystem, reflecting the rich biodiversity of Sri Lanka’s forests.
You can differentiate male and female Ivory Ornamental Tarantulas by their size and color. Females are larger, with a dark brown carapace and distinct cream and black leg segments. Males are smaller and more uniformly pale brown, with legs that appear metallic, lacking the female’s starburst pattern.
Yes, the Ivory Ornamental Tarantula is venomous, and its venom is considered medically significant. A bite can be quite potent, causing severe localized pain and other symptoms. Due to their strong venom, they are recommended only for experienced keepers who understand the potential risks involved with handling.
Adult Ivory Ornamental Tarantulas show a clear size difference between sexes. A mature female typically reaches a leg span of 8 to 9 centimeters (around 3.5 inches). In contrast, the mature male is smaller, generally measuring between 6 and 7 centimeters (around 2.7 inches) in leg span.
A Poecilotheria subfusca constructs an asymmetrical tunnel web, which is typical for an arboreal species. This web is usually hidden within tree bark or crevices and is not as elaborate as those of other species. The structure serves primarily as a retreat and is most visible at night.
In their natural habitat, Ivory Ornamental Tarantulas are nocturnal hunters whose diet consists mainly of various insects. As a key predator in their ecosystem, they help regulate insect populations. Their quick pounce and arboreal nature allow them to effectively hunt prey within the trees of Sri Lanka.
Ivory Ornamental Tarantulas are not considered overtly aggressive but are highly defensive and fast. They will typically try to flee from a perceived threat rather than attack. However, if they feel cornered or provoked, they are capable of delivering a quick and painful bite as a last resort.
Ivory Ornamental Tarantula spiderlings are a uniform brown color and are covered with fine hairs known as setae. They hatch from bright orange eggs but do not display the complex patterns of the adults. Their distinct adult coloration and markings develop gradually as they grow and molt over time.
