The largest spider by leg span in the world.


Huntsman spiders belong to the Sparassidae family and get their common name because they are efficient and lethal hunters. There are 96 genera and 1383 species as of 2021. They are usually large, hairy spiders that hold their legs crabwise, which gives them the alternate name of giant crab spider. Most are gray or brown but may have bands and markings over their legs and bodies. They have eight eyes and fairly good eyesight. Like other spiders, they are venomous as opposed to poisonous, and some are capable of inflicting painful bites on human beings. But like other spiders, their venom evolved to subdue their regular prey. Some people welcome huntsman spiders in their homes because they eat pests such as cockroaches.

4 Incredible Huntsman Spider Facts!

  • Huntsman spiders are surprisingly gentle during courtship. Males in many species drum their abdomens or their legs on the ground to crate vibrations that are interesting to the females, who lure them with pheromones.
  • Female huntsman spiders are fiercely protective of both their eggs and their young. They keep their eggs in a sac or purse made of silk and will either stand guard over it or carry it in her jaws. When the eggs hatch, she’ll guard the spiderlings until they molt several times. This can take weeks, and during that time the mother spider doesn’t eat.
  • While some huntsman spiders are solitary, others live happily in large colonies.
  • Though huntsman spiders don’t spin webs, they’ll spin a sort of cocoon out of silk when it’s time for them to molt or lay eggs.

Huntsman Spider Species, Types, and Scientific Name

The classification of the huntsman spider puts them in the Sparassidae family, which is broken down into classifications of genera and species. There are e nearly one hundred genera and over 1300 species of giant crab spiders. By the way, the Sparassidae family isn’t closely related to proper crab spiders, who are members of the Thomisidae family. Among the genera are the:

  • Carparachne: This genera contains the fascinating cartwheeling spider, Cebrennus rechenbergi. This spider actually cartwheels to get away from threats, and it’s the only spider known that does this. It’s found in Morocco and is also called the Moroccan flic-flac spider. A robot was actually built to mimic this spider’s movements.
  • Diminutella: As its name suggests, this is one of the tiniest of these giant spiders. The body length of the female Diminutella cortina is only 0.14 to 0.17 of an inch. It is found in Cuba and is the only species in its genus.
  • Heteropoda: The classification Heteropoda is a large genus that contains the brown huntsman, Heteropoda cervina. The genus gets its name because the legs of this giant arachnid are of unequal length, but this lets the spider scuttle sideways and change its direction quickly. The brown huntsman is known for living in houses in Queensland, Australia, but it is a timid spider that only bites when it’s threatened.
  • Leucorchestris: This classification contains the dancing white lady, Leucorchestris arenicola of the Namibian desert. The spider communicates with conspecifics by drumming with its front legs. The way it drums must e precise, for another spider can mistake its vibrations for prey and kill the spider that’s trying to communicate with it. The dancing white lady can also use its eight eyes individually to give itself panoramic vision.
  • Micrommata: The spiders in this genus differ from other huntsman spiders in that many of them are bright green. This includes Micrommata virescens, a huntsman that lives in the woods of northern Europe.

Appearance: How To Identify Huntsman Spider

It is easy to say that to identify a huntsman spider all that a person needs to see is a giant spider that it holds its legs like a crab. Yet, some species of huntsman spiders aren’t much bigger than regular crab spiders, and the brown recluse is also rather large and has a cancrine stance.

Crab spiders are also called flower spiders because they perch on flowers and ambush insects that light on the flowers. They can slowly change colors to blend in with the flower, but huntsman spiders can’t do this. Most are shades of brown or gray, though some species in the Micrommata genus are leaf green. Huntsman spiders also tend to be furry, and they can easily hide in small spaces despite their size. This is because their bodies tend to be flat, and they have those uniquely foldable legs. They are ambush predators and can also move surprisingly fast for their size.

Habitat: Where to Find Huntsman Spider

Huntsman spiders are found around the world save the coldest areas on earth. They hide in places that don’t see a lot of human traffic, such as garages, barns, and garden sheds. Some hide behind blinds and curtains and startle people who have come to adjust their window dressings. Huntsman spiders also shelter in cars and also startle people who try to adjust their rearview mirror. In the wild, they’re found under bark and under rocks. This gives them the name “wood spider.”

Diet: What Do Huntsman Spiders Eat?

Huntsman spiders usually eat small arthropods. They range from butterflies, cockroaches, and even scorpions. Some species eat other spiders and are indeed cannibalistic. Some huntsman spiders are big enough to take bats, mice and small lizards.

Prevention: How to Get Rid of Huntsman Spiders

There are many people around the world who welcome huntsman spiders into their homes because they eat pests. These are not only roaches and water bugs, but if the spider is big enough, it can even keep down a population of mice. Most huntsman spiders are docile and run away when they’re threatened. Yet it’s understandable if the homeowner really does not want giant poisonous spiders in their home. In that case, it is possible to call in a pest control expert and have them trapped and humanely removed.
