Can beginners keep this species?

It's generally considered an advanced-level species. Because it's fast-moving and defensive, prior tarantula-keeping experience is recommended.

Is its bite dangerous?

Bites from this species are said to cause more noticeable symptoms than many other tarantulas. If bitten, avoid self-treatment and consult a medical professional if needed.

How large does it grow as an adult?

Adult body length is about 4.5–5 cm for females and 3.2–3.5 cm for males, with females growing somewhat larger.

Sri Lankan Ornamental is listed in CITES Appendix II. International trade requires a permit from the exporting country, but as far as CITES is concerned, no registration is needed to buy or sell individuals already legally in Japan.

Does it need to be housed alone?

Sri Lankan Ornamental

The Sri Lankan Ornamental is an arboreal tarantula native to the forests of central Sri Lanka, and serves as the type species of the genus Poecilotheria. Its body shows an intricate camouflage of black, white, and grey, accented by a pale grey leaf-shaped band running the length of the abdomen. Quick-moving and strongly defensive when disturbed, it calls for careful, experienced handling. For keepers who want to observe a striking, wild-natured spider from a respectful distance, it's a rewarding but advanced choice.

About Sri Lankan Ornamental

An arboreal tarantula from central Sri Lanka, marked by black, white, and grey camouflage and a leaf-shaped band on the abdomen. Fast-moving and defensive—best suited to experienced keepers.

7 things to know before welcoming a Sri Lankan Ornamental

1An advanced-level species
This tarantula is fast-moving and strongly defensive when disturbed, making it best suited to keepers with prior tarantula experience rather than first-time owners.
2Arboreal enclosure setup
As an arboreal species, it needs vertical space rather than floor area. Set up cork bark or driftwood to climb, with crevices to retreat into.
3Highly defensive temperament
When startled or provoked, it reacts quickly and defensively. Routine care should be done with tools rather than bare hands to avoid triggering a defensive response.
4Bites and safety awareness
Compared with many other tarantulas, bites from this species are more likely to cause noticeable symptoms. If bitten, avoid self-treatment and seek medical advice if needed.
5Leave it undisturbed when molting
Before and after molting, the spider is especially vulnerable. Pause feeding and cleaning once you notice pre-molt signs, and keep its environment calm.
6Humidity and temperature control
Originating from tropical Sri Lanka, it needs consistently warm temperatures and elevated humidity in captivity. Balance ventilation with moisture retention to avoid extremes.
7House individually
Tarantulas carry a risk of cannibalism, so each spider should be housed alone. Prepare a separate enclosure, climbing material, and hide for each individual before it arrives.
