New Zealand arachnids
Te Papa researcher: Phil Sirvid
Aotearoa has a rich and largely unique arachnid fauna – there are over 1,100 known species of spider and about 95 per cent of them are found nowhere else on Earth. Opiliones (harvestmen) may not be as diverse as spiders (about 350 species and subspecies), but all but two are endemic, and they show a bewildering array of bizarre forms.
This research concentrates on these two arachnid orders and seeks to document new species, to better understand known species, and to explore the evolutionary history of these fascinating animals. This information also informs threatened species classification assessments for arachnids. Spiders are demonstrably a topic of great interest to visitors to the Te Papa website, so public outreach is an important focus.
