From Live Science:
They're peacock spiders, a group of tiny arachnids that are small in stature but giants in the charisma department, best known for their brilliant colors and energetic courtship "dances" — much like the showy, fan-tailed peacocks that inspired the spiders' name.More information at the Live Science link and in the video at the next post.
And scientists recently described seven new peacock spider species — so let the spider dance party commence! [In Photos: 7 New Species of Peacock Spider]
Researchers found the newly described species — all of which were in the genus Maratus — in Western Australia and South Australia, bringing the total number of known Maratus species to 48. The spiders in this genus measure on average about 0.16 to 0.20 inches (4 to 5 millimeters) in length, with females a bit larger than the males.
Females that belong to this genus tend to be dappled in different shades of brown. But it's the males' dramatic coloration that catches the eye and prompts biologists to assign them whimsical nicknames like "Sparklemuffin," which was bestowed upon a peacock spider species described in 2015. Colors and patterns are displayed on the males' abdomens, frequently on a "fan" — a flat structure that is lifted up toward the female during the male's courtship performance.
