A giant spider that looks like a crab was found in the sea off of New Caledonia. The spider, coined “the world’s most terrifying animal,” is called Halitherses Grimaldi. Spiders are not insects, but they have eight legs and two body parts: the head and abdomen. Spiders can be classified into three groups: true spiders (e.g., black widow), wolf spiders, and funnel-web tarantulas.

#1. Goldenrod Crab Spider

The Goldenrod Crab Spider is also known as the “Goldenrod Spider” or the “Saddleback.” This spider has four pairs of eyes that are arranged into two rows. The upper row consists of an anterior median team and posterior-lateral pair; these eyes have a slight depression in front. The lower row contains two posterior median pairs and one anterior-lateral pair.

Spiders with this arrangement are called haplotype spiders, which means they lack a scape on their backside (the scape is a projection from the cephalothorax to hold part of the abdomen). These spiders can be found throughout North America, except for the northernmost regions. They live in open fields where goldenrod grows along fences or other structures such as barns. The spider preys on other insects, such as flies and mosquitoes.

#2. American Green Crab Spider

American Green Crab Spider is a type of spider with the scientific name of Misumena vatia. It is found in North America, Eastern Canada, and the Eastern United States. They are notable for their resemblance to crabs, hence the name crab spider.

They are usually green or brown but can change colors depending on where they live. They have six eyes which gives them an excellent vision to see prey from afar.

Green crab spiders are ambush hunters that prefer to attack prey from behind because it has less chance of escape if it doesn’t feel threatened at first sight by their attacker.

#3. White-banded Crab Spider

The white-banded crab spider is also known as the flower spider because it often hides in flowers, waiting for prey to come by. This spider usually lives near water and likes to spin silk webs over ponds or streams. It has a brown body with black markings that look like stripes across its back.

The female can grow up to 4 centimeters (1 ½ inch) long, while the male-only reaches about 3 millimeters (a little more than 1/8 inch). The web of this species is solid because it contains glue secretions from glands on its abdomen.

When an insect gets stuck in the web, the white-banded crab spider immediately rushes out and wraps it tightly in silk before biting it to paralyze it with venom. It then drags the prey back to its hiding place.

#4. Northern Crab Spider

Northern Crab Spider. The Northern crab spider is also known as the flower spider due to its flower attraction, but it can be found in gardens, fields, and forests. It has a distinctive violin-shaped marking on its back with two long “horns” extending down each side of the body.

These creatures are brownish-green with yellow markings on their underside (underside). They live in warm climates in North America, Europe, and Asia. Some species have an iridescent sheen that shimmers in sunlight or moonlight when they move about at night hunting prey.

#5. Black-banded Crab Spider

The Black-banded Crab Spider (Ixodes scapularis), also known as the deer tick, is a hard-to-spot arachnid found in woodlands with high grasses.

The Black-banded Crab Spider prefers areas with easy access to its prey, usually small mammals like chipmunks and squirrels. This spider’s habitat ranges from the Atlantic coast, spanning up into Canada.

#6. Tuberculated Crab Spider

The Tuberculated Crab Spider is a spider that looks like a crab. It has two large, white spines on its back which give it claws and legs. Locally they are called “Crab Spiders” because of this illusion. They live in warm climates such as Australia and South Africa

and prey upon insects and other arthropods, using their powerful front legs to catch them before biting with their chelicerae (jaws). The female Tuberculated Crab Spider can lay up to 100 eggs at once into an oval-shaped sac and then carry these around on her abdomen until they hatch; she protects them fiercely from potential predators such as birds or wasps who might try to eat them.

#7. Tan Crab Spider

One of the most common misconceptions about spiders is that they are all dangerous. In reality, only a tiny percentage of spider species threaten humans.

For example, the crab spider belongs to a family called Thomisidae, and it has distinctive markings on its back, making it easy to identify as one of the harmless ones. The crab spider’s diet consists mainly of flies, other insects, and tiny land snails, so this creature poses no danger to people at all. In fact, these spiders can be quite beneficial because they prey on some pests like mosquitoes and ticks!

They also help gardeners by eating aphids for plants to grow better without damaging pests.

#8. Elegant Crab Spider

A spider that looks like a crab? You guessed it, this is the Elegant Crab Spider. The spider’s body has markings resembling those of the red rock crab, and its leg joints are shaped to give it an almost perfect resemblance to a tiny hermit crab.

The Elegant Crab Spider is so good at camouflaging itself with its environment that people have mistaken them for baby crabs or other animals before discovering they were spiders.

To complete their disguise, these spiders also change colors depending on where they live – in dry areas, they turn greyish brown, while in humid forests, they are dark reddish-brown or black with white spots. This spider can be found throughout North America from Canada southwards into Mexico and often runs across roads during wet weather.

#9. Swift Crab Spider

It’s funny how crab spiders look like crabs. They’re not really related, but it’s a common misconception that they are. Crab spiders are arachnids, and their name is derived from the two front pairs of legs which resemble claws or pincers.

The spider has an oval-shaped body with a hard carapace on the top of its abdomen and eight eyes arranged in two rows – six small ones above and two large ones below. It is usually brown, orange, or yellowish with white spots on its sides, back, and legs to confuse potential predators and prey insects looking for a place to land. In fact, many people call them “false scorpions.” There are more than 1,500 species worldwide!

#10. Multicolored Bark Crab Spider

The Multicolored Bark Crab Spider is a colorful, crablike spider with long spindly legs and an elongated abdomen. They are tree-dwelling spiders with a worldwide distribution. It lives in the leaf litter on the forest floor, under rocks or logs, and inside plant stems. These spiders can grow up to 20 mm in length (about 4/5 of an inch). The coloration of this species varies geographically; they may be green or blackish brown with yellow bands, red spots or stripes on their body, orange legs, and chevrons on their back.

The most distinguishing characteristic is its large size relative to other related species within the genus “Diaea.” This spider’s bite produces no known harmful effects to humans.

#11. Diaea Livens

Diaea livens a type of crab spider that closely resembles a crab.

The abdomen has markings, or tubercles, which form a pattern to imitate the appearance of a crab’s shell. The front pair of legs are longer than the other six pairs and have been modified into large claws with scissor-like action for capturing prey. It belongs to the family Thomisidae.

Diaea livens been found in many countries, including Australia, China, India, Korea, New Zealand, and parts of Africa and Europe such as Portugal and Italy. Other common names include “crab spider,” “spider crab,” “flower spider,” and “beautiful flower spider.”

#12. Deadly Ground Crab Spider

The Deadly Ground Crab Spider is one of the most venomous spiders in Australia.

The spider is usually found living on the ground, hence its name. The area around this spider’s burrow can be challenging to walk through without putting your feet into it. It also has a habit of running away when disturbed and will often flee to an adjacent burrow rather than confront its attacker head-on. This fleeing behavior makes bites more likely if someone stumbles onto the spider while searching for it.

#13. Giant Crab Spider

Don’t be fooled by its name. The Giant Crab Spider is not a crab, but it has an uncanny resemblance. This spider usually lives on the ground and hunts for prey near it. When they feel threatened, they will rear up their front two pairs of legs like pincers to scare off predators before scurrying away into safety under logs or rocks. They are nocturnal spiders, so you won’t find them out in the daytime unless they mate or look for food, including small mammals, birds, and other insects.

#14. Pantropical Huntsman Spider

The Pantropical Huntsman Spider is a giant spider. It can grow up to 12 inches in body length, with legs that are 6 inches long. They are also known as the Giant Crab Spider because of their size and appearance. The best way to tell them apart from other spiders is by looking for an orange hourglass-shaped marking on their underbelly, which resembles a crab claw.

#15. Oblong Running Spider

The Oblong Running Spider is a spider that looks like a crab. They are not native to the United States, but they now live in California and parts of Oregon. The spiders were accidentally introduced into these regions by humans who imported goods from other countries. This type of spider is also called the Yellow Sac Spider because females carry their egg sacs with them wherever they go.

Females can produce up to four egg sacs during one season, and each sac contains up to 200 eggs that hatch within two weeks after being laid. These spiders are usually brown or yellow-colored with long legs that dash over surfaces, including fences, tree limbs, rocks, logs, and even water!

#16. Metallic Crab Spider

A distinctive and colorful spider, the metallic crab spider, is found in South America. It’s also known as the golden orb-weaver or golden silk orb-weaver.

The metallic crab spider is about 1/2 inch long and has a light brown body with bright orange legs and violet lines on its abdomen. The female lays her eggs inside an egg sac that she weaves from silk, usually near where she lives or finds food. When they hatch, the baby spiders stay within their mother’s web for a time until they mature enough to leave on their own and find food elsewhere. They don’t need water because they get all the moisture they need from eating: other insects!

#17. Eurasian Running Crab Spider

The Eurasian Running Crab Spider is a venomous spider native to Europe and Asia. It has been introduced in North America, where it can be found in the Northeastern United States. The species was accidentally introduced into British Columbia, Canada, around 1900. It is thought that they may have arrived with shipments of European apples because the spiders are often seen near apple trees or homes with apple trees nearby.

The spider’s common name comes from its ability to run across wet surfaces such as rain-soaked ground or puddles without sinking into them. This type of surface running behavior is called “crab-walking.”

#18. Selenops Submaculosus

Selenops Submaculosus is a spider from the Caribbean, Central America, and South America. It mainly lives in tropical forests near rivers or other sources of water. The Selenopidae family are sometimes called “spider crabs” because they have long front legs resembling a crab. They catch their prey by hunting them on the ground at night-time and then wrapping them up to be eaten later. Selenops Submaculosus also has a unique way of catching its prey: it uses silk as bait for unsuspecting insects, which get seen when landing on it, making this creature an expert hunter!

#19. Spinybacked Orbweaver

The Spinybacked Orbweaver is a spider that looks like a crab. They are often found in woodlands and forests near water sources, hunting for snails to eat. These spiders are harmless to humans but can be very dangerous to small animals such as frogs or lizards!

What Does a Crab Spider Look Like?

So what do crab spiders look like? You may be surprised to know that they don’t actually resemble crabs at all. They are named for their long front legs, which usually have spikes on the ends. These limbs allow them to run across wet surfaces without sinking in.

Most crab spiders are brown or yellow-colored with long legs and round abdomen. Females carry egg sacs around with them wherever they go, so it is easy to identify females by looking for an orange hourglass marking on their underbelly resembling a crab claw. Males are smaller than females and don’t have this marking but can still be identified because of the distinctive black spot near their head region known as the “terminal apophysis.”

Where Does the Crab Spider Live, and What Does it Eat?

The crab spider is an arachnid, not an actual spider. It lives outdoors in moist environments like marshes and gardens, where it hunts for insects. The crab spider has the unusual ability to use its front legs as “legs” or “arms” while hunting instead of just using them to walk around on.

When the crab spider spots prey, it lunges at it with its forelegs outstretched to catch it. Then the crab spiders bite into the prey’s body with powerful fangs that inject poison from glands near their mouthparts called chelicerae which then kills the insect by dissolving its tissues.

Are Crab Spiders Venomous?

Many people believe that crab spiders are venomous, but this is not true. Crab spiders are actually harmless to humans. The myth of their venomosity likely arose because they resemble other species like the brown recluse and black widow that can inflict painful bites with their potent venoms.

How are Crab Spider Bites Treated?

Crab spider bites are very dangerous. The poison is neurotoxic and can affect the brain, heart, or lungs. A few tidbits can be fatal without treatment. Fortunately, there are effective treatments available to stop the spread of this dangerous toxin.

How to Identify a Crab Spider

A crab spider is a type of arachnid that looks like it could be related to the crabs. The name “crab spider” comes from its long, spindly legs and its ability to scuttle sideways in an almost crablike fashion. They are often found on plants or flowers where they feed on living insects or scavenge dead ones. When these spiders feel threatened, they typically will either flee or raise up on their hind legs with their front paws raised as if asking for a handout. This defensive stance makes them look much more significant than they actually are and helps deter predators by making them seem formidable; after all, who wants to mess with something that can give you such an ugly bite?

Identifying a Crab Spider

Crab spiders are a type of arachnid, and they get their name from the way they walk. They move sideways like crabs or crayfish. This makes them very difficult to catch! They also have two sets of eyes on the top of their head that help them see in front and behind themselves simultaneously. The first set is called “simple eyes” because it only has one lens – while the second set is called “compound eyes” because each eye has a cluster of lenses called an ommatidium.

When you spot a crab spider, look closely for these features:

  • Six short legs with two claws at the end.
  • Four long spinnerets near its rear end where it spins silk.
  • Four simple eyes on top of the head.

Recognizing Crab Spider Habitats

The crab spider is a common household pest. It’s the largest of all spiders, measuring up to two inches across its body. They are grayish-brown in color and have six long hairy legs with reddish-orange crablike claws at the end. You can find these creepy crawlers running around your basement or bathroom, but you should never attempt to grab one by hand because they will bite you if provoked!

The best way to catch them is using a jar or glass that has been coated with cooking oil on the inside. The oily surface prevents them from climbing out after they’ve fallen in, so use this method whenever you see one of these creatures entering your home…

Handling Crab Spiders in your Area

If you live in an area where crab spiders are expected, then chances are that you’ve seen one before. The name “crab spider” is a misnomer; these creatures aren’t related to crabs. They’re the largest of the three types of orb weavers and can range from four millimeters (1/6 inch) to well over 10 centimeters (4 inches) in length! These scary-looking arachnids usually grow slowly and don’t bite humans unless handled or provoked.

Here’s how to handle them: 

  • If the spider is in a web, gently shake the web to make the spider fall off. If it’s on a surface, use a piece of paper or card to carefully scoop it up and release it outside.
  • Never try to kill or squish the spider; this will only cause them to release their venom, which can be dangerous if you’re allergic.
  • If you’re having trouble removing the spider, it’s best to call a professional. Pest control experts will have the experience and equipment necessary to safely remove any spiders from your home or workplace.
  • So there you have it – how to handle crab spiders in your area! As long as you exercise caution and don’t provoke them, these eight-legged critters should cause no harm. Enjoy observing these exciting creatures from a safe distance!
