Newly discovered spider has happy face on its back
Researchers have discovered a new species of spider in the Himalayas that resembles the famous Hawaiian happy-face spider. Named Theridion himalayana, this spider showcases a variety of smiley patterns on its abdomen. The discovery highlights the biodiversity of the Himalayan region and raises questions about the evolutionary relationship between the two species.
- ▪The Himalayan happy-face spider was discovered during a biodiversity survey in Uttarakhand, India.
- ▪This new species shows about 8.5 percent genetic variation from the Hawaiian happy-face spider.
- ▪Both spider species have a preference for ginger plants, despite ginger not being native to Hawaii.
