1: Sparklemuffin
This Australian peacock spider was discovered inside the woodland forests of Wondul National Park, near Brisbane, in 2015. Scientifically named maratus jactatus, sparklemuffin earned its colloquial name from University of California researcher Madeline Girard, who discovered the species. These colorful spiders measure just five millimeters in length and display a signature mating dance, where male spiders raise a leg to signal females.
