How Many Legs Do Spiders Have?

If you’re wondering how many legs spiders have, you’re not alone! Many of us are stumped about this question, which has prompted me to create an infographic for everyone to see. Below are the most popular answers to the question “How many legs do spiders have?”

Eight legs

Why do spiders have eight legs? These spiders use their limbs for sensory functions, including jumping, and are able to generate up to eight times their own weight when hopping. Despite the lack of antennae, spiders use their limbs to pin prey and deliver venom from their fangs. Researchers once believed that having eight legs gave spiders a mobility advantage, but recent studies show that a higher number of legs hinders movement.

Six legs

You may have heard that spiders have eight legs, but they actually only have six! That’s because some species have only six legs, while others have as many as eight! Whether your spider has six legs or eight is up to you, but remember to be gentle! If you’re encountering one, be sure to count them! And never touch them! You never know when you might get bitten by a spider.

Seven legs

Most spiders have eight legs, compared to six for insects. They lack antennae, but their legs still generate eight times as much pressure when moving. Spiders have seven segments: the coxa, the trochanter, the tibia, the patella, and the metatarsus. Their front pair of legs is used for sensory functions, while the other pairs are used for movement and climbing. Most spiders have two pairs of claws, but the Australian crab spider does not have claws.

Four legs

Almost every species of spider in the world has four legs, or a total of eight. Spiders use hydraulic pressure to move their legs, and they do not need an extra leg. While many spiders do not have antennae, they use their legs to hunt insects and build webs. Spiders do not use all of their legs at the same time when hunting or building webs, but two pairs are sufficient for these functions.

Five legs

Spiders with two legs have no issues functioning. However, spiders with three or four legs have difficulty in hunting and building webs. Spiders with five legs have issues in these areas and need more legs to function properly. Scientists at the University of Nancy, France, studied the life cycle of the Zygiella x-notata spider to understand why spiders with five legs are more effective at building webs.

Tarantulas

There are eight parts to a spider’s body, and each segment has two segments called the coxa, trochanter, femur, patella, tibia, and metatarsus. These segments are referred to as legs because spiders use them to walk, but they can have more than one set of legs. In addition to their legs, spiders also have two small appendages in front of their heads called the Chelicerae. They are responsible for detecting vibrations and air currents and are capable of picking up sounds.

Less than eight legs

Did you know that spiders can have less than eight legs? Most spider species have eight legs, but some can have seven, even six. This is because spiders are born with eight legs. Spiders may have less legs if one of them breaks off. Depending on the species, less than eight legs on spiders can make the spider appear smaller or even dead. In general, spiders should be handled gently.

Ten legs

Did you know that spiders have 10 legs? These creepy crawlers have the largest jaws of any arachnid species. They are also known as sun spiders and camel spiders. They belong to the arthropod order, which also includes insects and crustaceans. Most of these creatures live in the sea. The order is called decapods and is made up of familiar groups like spiders, millipedes, and scorpions.

Twelve legs

The spider’s unique body structure is based on the placement of its eight simple eyes on its cephalothorax. They usually have four pairs of legs. Spiders have short, leg-like palps between their jaws and legs, which males use to transfer sperm to their female partners. The female spider then produces a nuptial web, containing a dark spot called the sclerotized epigynum.

More

Many spiders lack eight legs, and some species can do just fine without them. Six-legged spiders, for example, can catch prey with ease. These spiders are still considered arachnids, and are classified as insects. In the past, scientists thought spiders should have eight legs, but it turns out that they do just fine without them. These arachnids are a bit more vulnerable, but they aren’t in imminent danger of extinction.
