Nephila komaci

Nephila komaci is recognized as the largest known species of golden orb-weaver spider in the world. The females have bodies that can exceed 4 centimeters (1.5 inches) in length, with a total leg span reaching up to 12 centimeters (nearly 5 inches). The males, however, are vastly smaller, exhibiting extreme sexual dimorphism.

This rare spider is native to southern Africa, with confirmed populations found in South Africa and Madagascar. It prefers warm climates and weaves its massive webs in forests and savanna woodlands. It was only officially identified as a new species in 2009.

Like most golden orb-weavers, Nephila komaci is relatively harmless to humans despite its intimidating size. Its venom is a neurotoxin effective on its small insect prey but is not lethal to people. A bite would typically only result in localized redness, slight swelling, and mild pain.

The species was officially described in 2009 by researchers Matjaž Kuntner and Jonathan Coddington after analyzing specimens collected in South Africa. Interestingly, it was originally identified from museum collections before live specimens were ever observed in the wild. It is named in honor of Kuntner's best friend, Andrej Komac, who died shortly before the discovery.
