The comb-footed is a family of spiders with more than 1,000 different types of spiders. They show many colors, but the most common are dark-brown, light-brown, gray and black. Sometimes, these spiders have patterns and markings on their backs in orange, yellow, white, red, green and other colors. As other families of spiders also have bodies with these colors, it is very difficult to tell if a spider is a "comb-footed" only by looking at its colors.
Comb-footed spiders are not the biggest spiders in the world. Most comb-footed spiders have bodies smaller than 0.5 inches, but they look bigger because of their eight long legs. Female spiders have big and round or triangular bellies and are bigger than males. Sometimes, females are twice or three times as big as males.
Comb foot spiders can bite if they feel in danger, so never try to catch one. Many types of combed footed spiders have a poisonous bite and can make a person feel very ill. The black widow is the most poisonous type of comb-footed spider. It is black and shows red spots or other markings on its back and belly.
The females can lay as many as 400 eggs at a time. They keep these eggs inside a sac, which they make with silk. When the baby spiders hatch, they need to look after themselves and generally do not live long close to their mother. After mating, some comb-footed male spiders, such as the black widow, die. Sometimes, the females kill the males and eat them. Females can live up to 3 years while males live about 6 months.
