Giant Crab Spider


The giant crab spiders, also known as huntsman spiders, are giant spiders that can compete with tarantulas in size. Although this spider is a flat-bodied spider, it can still scurry to narrow cracks and crevices because of their laterigrade legs (legs that extend forward that is similar to a crab’s leg). Mature males are 1/2 to 1 1/5 inch while the mature females are 3/5 up to 2 inch in body length. Their legspan is 50 to 64 millimeters in length, adding to that giant look. These spiders are also found with brown or gray spots all over, and a striking black and white mark on their undersides.


Giant crab spiders do not build webs, but they are natural hunters and predators. They can be found under rocks or on tree barks if they are in their natural habitat. When they are found indoors, these spiders can be in garages, and in sheds where they will not be seen or disturbed.


As the giant crab spiders search for prey, they will climb up into high places so they can observe wide areas without being seen. Although they like to climb, they are also a non-visual hunting spider, where they use their other senses to know when their prey is coming. And, even if they are big, they can still run fast, which allows them to catch their prey easily. Once they find something to eat, they will ambush their prey and inject it with their venom.


This spider like to eat other small insects, crickets, small skinks and geckos that they can subdue easily.

Life Cycle

A female giant crab spider can live for 2 to 3 years, compared to the male giant crab spider that has a short lifespan because they are commonly consumed by the female after mating. After she releases her eggs, she will place them in a sac and will carry it below her body. She will not feed during the incubation period, and will protect her sac and the spiderlings after they come out. These spiderlings will stay under her protection for a while, until the time that they disperse.
