Poecilotheria regalis is a species of arboreal tarantula and is found in parts of India.

In the wild individuals live in holes in tall trees where they make asymmetric funnel webs.

It is not unknown for the spiders of this genus to live communally when territory, i.e. the number of holes per tree, is limited.

In addition to the direct effects of the venom, the large fangs can produce puncture wounds which themselves can lead to secondary bacterial infection if not properly treated.

There has never been a single reported case of anaphylactic shock from tarantula venom, and it is very likely that they do not contain the proteins needed to enact the potentially deadly allergic reaction.
