Yup! They really do dance!
Adults
Size: All the species of this genus are small-sized, being 4mm to 5mm (0.15 inches to 0.20 inches) long.
Color: The females, as well as the juvenile spiders of both the sexes, have a brown body, though with distinct mottled patterns of brownish and whitish scales. The males, on the other hand, come in colors of blue, red and yellow on the upper part of their abdomen. However, not all species of this genus appear bright to the human eye, for instance, the Maratus vespertilio, which have an ambiguous coloration, with the iridescence present on its lateral flaps.
Other characteristics: The males are characterized by a fan or plate on the upper part of their abdomen that is marked with bright-colored scales or hairs forming a pattern where the foreground and background stand in contrast with one another. The males, as well as females, have their abdomen joined with the cephalothorax by a pedicel which is long and flexible.
Eggs
The female spider lays about half dozen eggs within a silken sac after the completion of the mating process and guards them intently till the time they hatch.
Spiderlings
The spiderlings are mostly of a brown shade with a distinctive pattern and disperse to be on their own after a two-week span.
The Web
Like all other jumping spiders, the species of this genus do not construct webs but keep producing silk as they move about in their surroundings. In fact, they are bold enough while stalking their preys and are known to pounce upon creatures that are thrice or four times bigger than them.
Do Species of Peacock Spiders Bite and Are They Dangerous to Humans
They are venomous but not dangerous to mankind as they may bite only accidentally, and their jaws are too small to even penetrate through the human skin.

Did You Know
- The splendid courtship dance performed by the male members of this genus to attract a female to mate is indeed an interesting one. The bright, vibrant surface of their upper abdomen, often having fringes and extensions are brilliantly displayed during this time.
- There are two different mechanisms for producing color, with one being the use of pigments for producing the cream, red and white shades. The other one involves the usage of nanostructures to produce blue.
- Entomologist, Jürgen C. Otto, has filmed the video of the remarkable dance of this species.
- Ferdinand Karsch a curator of Berlin’s Museum für Naturkunde described this genus for the first time.
- Peacock spiders have a special way of protecting themselves from predators and capturing their prey. Although they cannot fly, they have the ability to jump at a height of about forty times greater than their body length and catch preys.
