Some people love them, and some hate them. Regardless of whether you’re an arachnophile (a person who loves spiders) or an arachnophobe (someone who doesn’t), you’ll find these 10 facts about spiders fascinating.

Their Bodies Have Two Parts

All spiders, from tarantulas to jumping spiders, share this common trait. The simple eyes, fangs, palps, and legs are all found on the anterior body region, called the cephalothorax. The spinnerets reside on the posterior region, called the abdomen. The unsegmented abdomen attaches to the cephalothorax by means of a narrow pedicel, giving the spider the appearance of having a waist.

Most Are Venomous

Spiders use venom to subdue their prey. The venom glands reside near the chelicerae, or fangs, and are connected to the fangs by ducts. When a spider bites its prey, muscles around the venom glands contract, pushing venom through the fangs and into the animal. Most spider venom paralyzes the prey. The spider family Uloboridae is the only known exception to this rule. Its members do not possess venom glands.

Some Even Hunt Birds

Spiders hunt and capture prey. The majority feed on other insects and other invertebrates, but some of the largest spiders may prey on vertebrates such as birds. The true spiders of the order Araneae comprise the largest group of carnivorous animals on Earth.

They Can’t Digest Solid Foods

Before a spider can eat its prey, it must turn the meal into a liquid form. The spider exudes digestive enzymes from its sucking stomach onto the victim’s body. Once the enzymes break down the tissues of the prey, the spider sucks up the liquefied remains, along with digestive enzymes. The meal then passes to the spider’s midgut, where nutrient absorption occurs.

They Produce Silk

Not only can all spiders make silk, but they can do so throughout their lifecycles. Spiders use silk for many purposes: to capture prey, protect their offspring, reproduce, and assist themselves as they move, as well as for shelter. However, not all spiders use silk in the same way.

Not All Spin Webs

Most people associate spiders with webs, but some spiders don’t construct webs at all. Wolf spiders, for example, stalk and overtake their prey, without the aid of a web. Jumping spiders, which have remarkably good eyesight and move quickly, have no need for webs, either. They simply pounce on their prey.

Male Spiders Use Special Appendages to Mate

Spiders reproduce sexually, but males use an unusual method to transfer their sperm to a mate. The male first prepares a silk bed or web, onto which he deposits sperm. He then draws the sperm into his pedipalps, a pair of appendages near his mouth, and stores the semen in a sperm duct. Once he finds a mate, he inserts his pedipalp into the female spider’s genital opening and releases his sperm.

Females Eat Males

Females are typically larger than their male counterparts. A hungry female may consume any invertebrate that comes along, including her suitors. Male spiders sometimes use courtship rituals to identify themselves as mates and not meals.

Jumping spiders, for example, perform elaborate dances from a safe distance and wait for the female’s approval before approaching. Male orb weavers (and other web-building species) position themselves on the outer edge of the female’s web, and gently pluck a thread to transmit a vibration. They wait for a sign that the female is receptive before venturing closer.

They Use Silk to Protect Their Eggs

Female spiders deposit their eggs on a bed of silk, which they prepare just after mating. Once a female produces eggs, she covers them with more silk. Egg sacs vary greatly, depending on the type of spider. Cobweb spiders make thick, watertight egg sacs, while cellar spiders use a minimum of silk to encase their eggs. Some spiders produce silk that mimics the texture and color of the substrate on which the eggs are laid, effectively camouflaging the offspring.

They Don’t Move by Muscle Alone

Spiders rely on a combination of muscle and hemolymph (blood) pressure to move their legs. Some joints in spider legs lack extensor muscles entirely. By contracting muscles in the cephalothorax, a spider can increase the hemolymph pressure in the legs, and effectively extend their legs at these joints. Jumping spiders jump using a sudden increase in hemolymph pressure that snaps the legs out and launches them into the air.

Spider

16 × 8

Neutral (light > 11)
Hostile (light
Normal: 2
Hard: 3

Height: 0.9 Blocks
Width: 1.4 Blocks

Light level of 7 or less, 3×3×2 space on solid blocks (spawns only on top of the central block). Top half of space may be occupied by transparent blocks (glass, etc.).

Spiders are common neutral mobs that have the unique ability to climb walls.

Contents

Spawning [ edit ]

1-4 spiders spawn in a 3×3×2 space on opaque blocks in the Overworld.

They need only 1 solid block beneath at a light level of 7 or lower. The top blocks can be transparent, but not solid.

A spider spawns in leaves provided that there are 3×3×2 spaces around as forested biomes have a greater amount of spiders; they do not spawn in groups.‌ [ BE only ]

Spawners [ edit ]

Spider spawners are found in 25% of dungeons, as well as secret rooms surrounded by cobwebs in woodland mansions.

Status effects [ edit ]

This feature is exclusive to Java Edition.

On hard difficulty, spiders occasionally spawn with status effects. For each pack spawn, there is a (10×clamped regional difficulty)% chance of the game applying a status effect. This does not apply to cave spiders. If it decides to do so, then it selects the effect. The spider can spawn with following effects:

The effect is then applied to all entities within the pack with an endless length. If the Invisibility status effect is applied to a spider, its eyes remain visible.

A spider with the Speed effect.

A spider with the Strength effect.

A spider with the Regeneration effect.

A spider with the Invisibility effect.

Drops [ edit ]

Upon death, a spider drops:

  • 0–2 String . The maximum is increased by 1 per level of Looting, for 0-5 string with Looting III.
  • 5 when killed by a player or tamed wolf.
  • A 1 ⁄3 chance of dropping a spider eye when killed by a player or tamed wolf. The maximum amount of spider eyes is increased by 1 per level of Looting. The chance of a spider not dropping any spider eyes can be found using the formula 2 / (Looting Level + 3) . For example, Looting III gives a 1 ⁄3 chance of not dropping any spider eyes. All other amounts have an equal chance of occurring.

Behavior [ edit ]

Spiders are hostile to players and iron golems as long as the light level immediately around them is 11 or less; otherwise, they do not attack unless attacked. Hostile spiders see up to 16 blocks, continuing to chase even when exposed to well-lit locations. If a spider sustains damage from a source other than a direct attack, such as falling, its hostility is reset.

Spiders can climb up over solid blocks but not overhangs or on ceilings. If a spider cannot find an ideal path to the player, when they go behind or on top of a wall, it approaches as close as it can to the player’s position from the outside or below as it can see through blocks, at that time proceed by climbing the wall vertically until it gets to the top, even if it loses its aggression toward them. When a spider loses its aggression, it continues moving forward blindly for 2 seconds; this behavior causes the spider to climb up any walls in its path.

Spiders cannot climb magma blocks.‌ [ BE only ] [1] Note that Cave Spiders, on the other hand, can climb them on all editions.

If a spider tries to go through the world border, it starts climbing the world border instead.‌ [ JE only ]

If shot with arrows whereas outside of the detection range, spiders turn and run in the direction from which the arrow was fired. If the player moves away, the spider continues following the same path unless the player enters the detection range, in which case the spider changes direction and attacks.

Even though spiders do not inflict the Poison status effect, they are immune to it. They are also immune to the slowing applied to most mobs when walking through cobwebs.

An aggressive spider pounces at close range. Whether it is swimming in 1-block-deep water, it pounces upon touching the submerged floor. They can attack when their Y-axis position is changed.

Spiders flip onto their backs when they die, unlike all other mobs, which land on their sides.

They were the first arthropod to be added to the game. The Bane of Arthropods enchantment inflict Slowness IV and more damage to spiders.

Variants [ edit ]

Spider jockeys [ edit ]

There is a 1% chance for a spider to spawn with a skeleton riding it, forming a spider jockey. In the Nether, a spider spawned there with a spawn egg, commands or spawners, has a 0.8% to spawn a wither skeleton on its back and form a wither jockey instead. In some of snowy biomes, a spider has a 0.8% to spawn a stray on its back and form a stray jockey instead. A spider jockey can also be spawned by the command /summon spider

Critic Reviews for Spiders

It’s right in the middle ground as a mediocre missed opportunity with moderately respectable special effects.

It was directed by Tibor Takacs. Oh, you don’t know him? Well then you didn’t watch his earlier stab at cinema, Mansquito, which is the greatest TV movie of all time.

Only slightly better than a SyFy Channel monster movie, but you watch those too, I bet.

Doesn’t have the budget, the talent, or the ingenuity to really explore the potential of the premise.

Spiders 3D is something that surely should have went directly to the Sy-fy channel, premiering some Saturday night at 9:00 after a marathon of insect features like Mansquito, Ice Spiders, Camel Spiders, Spiders. you get my drift.

Evoked for me pleasant childhood memories of watching such «giant monsters on the loose» B-movies as «Them!,» «Tarantula» and «The Giant Spider Invasion.» Excellent special effects.

What has happened to America’s cheesy film industry? Where is the pride of our grade-Z filmmakers? Does no one care anymore about making decent bad movies?

The 7 Most Common Types of House Spiders

Illustration: The Spruce / Jiaqi Zhou

North America is home to about 3,400 species of spiders. Spiders are arachnids, and they’re related to scorpions, mites, and ticks. Unfortunately, spiders can and do make their way into our homes. Thankfully, the most common types of house spiders are harmless to humans, but there are exceptions.

American House Spider (Parasteatoda tepidariorum)

The American House Spider is a comb-footed spider, a common type known for its webs. They’re part of a group known as cobweb spiders, usually building the webs in places like basements, closets, and crawl spaces.

  • Color: Brown, tan, or greyish with darker brown patterns
  • Size: small to medium (about the size of a nickel including the legs
  • Features: rounded abdomen

Typically harmless, these spiders create messy webs that look unsightly.

Long-Bodied Cellar Spider (Pholcus phalangioides)

Sometimes referred to as daddy longlegs, the long-bodied cellar spider is not the same thing as a daddy longlegs. The Burke Museum states that while the daddy longlegs are also arachnids, they’re harvestmen, “ground-dwelling outdoor creatures,” with only one body section and two eyes. Spiders have two body sections and usually eight eyes.

The long-bodied cellar spider builds webs, often in basements, cellars, crawl spaces, garages, and other dark spaces.

  • Color: light brownish-tan, beige, or grey
  • Size: small, round body
  • Features: long, skinny legs

The cellar spider is not venomous.

Brown Recluse (Loxosceles reclusa)

The brown recluse is part of the brown spider family. According to the Department of Entomology at Penn State, the brown recluse is established in 15 states and can be found across the country in climates that range from the high humidity of Florida to the arid desert regions of Arizona and the cooler temperatures of the Midwest. You can find them indoors in basements, attics, crawl spaces, between walls, in furniture, and even in clothing. They’re often carried into the home via boxes and bags.

  • Color: brown or greyish
  • Size: oval body, about 1/3” long
  • Features: 3 pairs of eyes plus dark, violin-shaped marking on body

The brown recluse’s venom has a cytotoxin that can affect the tissue at the bite site. Medical treatment is needed, as dangerous reactions from the venom can occur. These may include but are not limited to chills, fever, rash, pain, and nausea. Children are more sensitive to spider bites than healthy adults and may suffer life-threatening reactions, reports the University of Rochester Medical Center.

Sac Spiders (Families Clubionidae, Miturgidae, and Corinnidae)

Sac spiders don’t make webs. It’s typical to discover these spiders near the ceiling or high along the wall. The sac spider is active year-round, usually at night.

  • Color: light-colored, yellow, beige
  • Size: oval body, about 1/2” long
  • Features: 2 rows of 8 small eyes

Harmless to most individuals, sac spider bites can produce swelling and slight soreness at the site. Anyone with spider bite allergies or sensitivities may experience a reaction that could need treatment.

Jumping Spiders (Family Salticidae)

Jumping spiders tend to hunt for prey during the day. You may spot them on the inside of a window, screen door, along a wall, or any surface exposed to daylight. They move in quick jumps.

  • Color: brown, black, tan, grey, beige
  • Size: compact, almost an inch long
  • Features: dense hairs, front legs that are longer than the others

The jumping spider’s bite is similar to a bee sting, but usually harmless. Children or anyone allergic to spider bites may experience a reaction, which can differ from person to person.

Wolf Spiders (Family Lycosidae)

Wolf spiders are larger than many of the other common household spiders. They may enter your home through foundation cracks, windows, or come in through an attached garage. Considered a hunting spider, they eat insects and even can make good pets.

  • Color: brown, black, tan, greyish-beige
  • Size: large, bodies longer than an inch
  • Features: elongated body with hairy-looking legs

Harmless to humans, brown-colored wolf spiders sometimes are mistaken for the brown recluse. However, anyone allergic to spider bites may suffer a reaction that could require medical treatment.

Hobo Spider / Funnelweaver (Tegenaria agrestis)

The hobo spider is considered an aggressive spider that builds funnel-like webs. They’re also known as funnelweavers and commonly mistaken for brown recluse and wolf spiders because of their brownish color. You may find them in dark areas of the basement or hiding under the fireplace wood pile.

  • Color: brown, tan
  • Size: oblong body about 1/2” long
  • Features: solid color with no markings

Funnelweavers or hobo spiders are not dangerous, but some people may experience irritation at the site of a bite. As with other spider bites, children can experience a stronger reaction than an adult.

Even though most common house spiders don’t pose a threat to humans, you may not want them sharing your home. If you have an invasion problem, there are plenty of ways to get rid of spiders. If you’d rather not fight them on the front lines, you can find help from a local spider extermination service.
