All About Spiders

Spiders

This page is dedicated to my favorite of all creatures: spiders.

Sure, some people think that they're gross, or scary, or yucky, but not me.

I like them, always have, and always will (unless one bites me and I die).

If you'd like to learn more about spiders, then read more on this page. I've included lots of links to websites about spiders to expand your knowledge.

- - - - What is a spider? - - - -

Are spiders insects? Nope! They're part of a group called arachnids. Spiders are related to insects, kinda like distant cousins. Insects, crabs, lobsters, centipedes, millipedes, and arachnids are all part of the group called arthropods (a group of animals that have segmented bodies). Spiders have two body parts and insects have three body parts. For more on arthropods, see: "Arthropods: The Largest Animal Group." Check out these diagrams of spiders, insects, and other arthropods.

How many legs do spiders have? They have eight legs (unless one gets chopped off). Insects have six legs (unless one gets eaten by a spider). Each leg has lots of hairs to sense the movement of nearby prey. Each leg is divided into seven parts (coxa, trochanter, femur, patella, tibia, metatarus, tarsus). Oh, a jumping spider can jump 25 times its height. That's a long way for such a small creature. Check out three diagrams of a spider and its leg.

How do spiders capture their prey? They use two methods: some spiders build a sticky web or and other spiders rely on their quickness or speed. 1st method: Surprise! The crab spider can jump on their prey. The trapdoor spider hides in a hole, then lunges out to capture unsuspecting nearby prey, and drags it back into its lair. Scary! 2nd method: sticky silk. Many spiders use the silk that comes from their spinnerets to catch insects that fly or wander by. Some spiders cast nets on passing bugs. Some spiders spit at passing prey (watch these three high-speed videos). Take this tough quiz on webs or visit this site on silk to learn more about webs. If you want to watch a tarantula capture a floor mouse, then check out this video. Would you like to see a video of a jumping spider leaping from one flower to another, and landing on a bee? Sometimes, they just sit on a long leaf and wait for a victim, like a frog, to wander by. Watch this fishing spider capture his dinner.

How do spiders make a web? That's a good question. A helpful diagram is at this website. Look at this diagram of a spider's web and the labeled parts.

Where on Earth do spiders live? They live on every continent except Antarctica.

How do spiders reproduce? They lay thousands of eggs in an egg sac. Now, that's a lot of spider diapers. To see a video of the mating rituals of a black widow spider and the egg sac that the female produces, check out this National Geographic video.

Are spiders good parents? Well, what we want to know is do they protect their babies from predators? The black widow female does, so don't try to mess with her. Ever.

What do you call a baby spider? Baby spiders are called spiderlings. Of course, when 1,000 come out of an egg sac, the mother would have a difficult time naming each and remembering who is who since they'd all be twins (x 100) and look alike. Click here if you want to see lots of spiderlings. Did you know that spiderlings molt once (because they grow bigger) inside the egg sac before crawling out.

Are spiders dangerous to humans? Two spiders can be very dangerous to humans (especially small children): the black widow spider and the brown recluse spider. Stay away from both! All other types of spiders in America are relatively harmless to humans. Of course, if you're a fly, then you'd better stay away from all spiders just to be safe or you might end up having dinner with a spider (and being the dinner). Thankfully, no one has died from a bite from either spider in the past two decades. Check out this spider identification chart. Read these myths about spiders. Check out wikipedia's article on spider bites. What are the symptoms of a black widow bite and what should you do (go to hospital). Did you know that there have not been any confirmed deaths to humans from tarantula bites? It's true. They hurt like a bee sting, but aren't deadly to humans.

How do people get rid of spiders? People step on spiders to kill them. Or, they use poisons.

Where do spiders live? Spiders can live almost anywhere that they can find food. They live in places where bugs crawl or fly by (so that they can capture and eat them. They live in hidden spots where bugs travel (under logs, in corners, in branches, under houses. Do they live on the Word Wide Web (www)? Read this digital book to find out.

How long do spiders live? Do they live for a day, a week, a year, or lots of years? Black widows live for up to 3 years, while tarantulas may live for 10-12 years.

How do spiders affect plants, animals, and people? Spiders help humans by eating the bugs that annoy us. Without spiders, there would be too many annoying insects flying around our food, biting us, and getting in our way. Of course, they also eat non-pests that help gardens (bees, butterflies, preying mantises, and some beetles).

What predators hunt spiders? As tough as a spider is, there are many other creatures that prey on spiders. Wasps are a formidable opponent (video). Other spiders will kill a smaller spider and eat it. Reptiles, birds, and some mammals hunt them, too.

How do spiders protect themselves from an enemy? There are four ways to protect themselves. They can try to escape (RUN). They can hide (camouflage). They can try to frighten them with an aggressive stance. They can attack, using their venom.

Where are spider ears? Spiders do not have ears. They can tell where a sound comes from by the movement of air on the hair on its legs.

Do spiders see well? Yes and No. Spiders that build webs to catch prey have bad eyesight. They use the hairs on their legs to feel the vibrating web (signaling that a bug has gotten stuck). Jumping spiders have excellent vision, as they need to see their prey.

Do spiders like to eat flies? Well, that would mean that they'd have taste receptors like humans. Humans have taste receptors on their tongues: sweet, salty, sour, and bitter. Spiders use taste-sensitive receptors on their legs to see if a captured prey is edible.

How big are spiders? The Goliath spider can be as big as a dinner plate. That's BIG! Most spiders you'll see are smaller than one of your knuckles. The smallest spider in the world is the Patu digua from Borneo and it is as big as the head of a pin. That's tiny.

Do spiders live by themselves or with others? Do they live by themselves or with other spiders? Are they friendly to each other or do they chase each other away?

Are spiders active during the daylight or darkness? They are active at night. In the daytime, they tend to hide in holes, cracks, or other safe places away from predators.

What do you call someone who studies spiders? They are called an arachnologist. A scientist who studies bugs is called an ectomologist. Here are some more websites: If you'd like to learn what an arachnologist does, then read more about Paula E. Cushing. A person who studies poisons is a toxicologist. They might be needed to determine the type of spider that bit someone.

- - Types of spiders - -

Black widow: This is a seriously dangerous spider, with venom that might make you sick or die. Never touch one. Ever! Thankfully, the smaller male does not bite. They're easy to find, as they're jet black with a red hour-glass shape on their belly. They're called "widow" because the female is prone to eating the male after mating (so they usually run away after mating, quickly). She'll try to escape if you get too close, unless she's guarding her egg sac. She may live for up to 3 years.

Brown recluse: This spider is quite dangerous, but you won't see it much. They're abdomen is dark gray or brown. They tend to bite when disturbed, so stay away from places where they might hide. They're more common in Texas and nearby states, not California.

Tarantula: These large, hairy spiders are relatively non-dangerous to humans. In fact, lots of kids have them as pets. One even lived for One even lived for 30 years. Most are brown or black. Many have bald spots on the back end of their abdomen, as they will rub the hairs off the hind end to irritate the eyes of predators. They live alone and are generally nocturnal. Click here to see a short video about tarantulas.

Garden Spiders: Thee colorful spiders scare the willies out of most people, but they're only dangerous to you if you're a fly. The yellow & black argiope is quite beautiful. Cornell Univ has several photos of common garden spiders.

Jumping spiders: These acrobats of the spider world are amazing when seen on video or. Check out hundreds of photos or this image of a jumping spider leaping toward a bee.

Goliath bird-eating spider: These are the largest spiders in the world, as large as a dinner plate, but you won't see one in your back yard (unless you live in a South American jungle).

Wolf spider: These spiders are indeed kind mothers, carrying their spiderlings on their backs.

Fishing spider: These quick spiders can dart into the water after prey (insect, minnow).

Crab spider: The crab spider crawls like a crab, with crab-like legs. More facts. And more. And more.

Daddy Longlegs: Well, the truth is, we humans keep mixing up these many-legged creatures. There are two types of daddy longlegs. One is a spider and one is not. 1) One daddy long legs is a spider, with the very long legs. It often builds its nest under houses or in cellars. When sensing danger, it'll shake its web, making it difficult for the predator to see it. 2) The other type is not a spider, though it looks like one, with long, long legs. Watch this video to see one in action, eating aphids and escaping from a hungry beetle.

Funnel web grass spider: This is one of the most common spiders you'll see outside. They're harmless to humans. They build a large funnel-shaped web that is not sticky. When a bug lands on it, the spider rushes out, bites it, and drags it into its lair. Mmmmmm. Dinner. They have 4-8 eyes.

Advice to my students on authoring their own Animal page

1. Use primary sources whenever possible. These are sources with video or images of the animal you're studying. These are web sites that are built by large organizations (like the discovery channel). You'll come across student websites and adult websites, but these are secondary sources (and less reliable in their information).

2. Be aware that some websites lack scientific facts. Or, they include a few scientific facts while trying to promote a hidden agenda. Not everything that you see at a website is supported by science. Be skeptical and don't believe everything you read. Look at other websites to see if they also make the same claim. Information that is found on a lot of websites has more validity than information found only on one website.

3. Use Videos that demonstrate a behavior of your animal. Don't post funny or dangerous videos just because you find them online. The most popular and prolific use of videos is hosted by You Tube. Here, you'll find many videos of your animal. However, any video that encourages violence or humor at the expense of your animal should NOT be included on your page. If you include a video, explain what it tells about your animal and be sure that it is factual (not humorous).

4. You are expected to be the EXPERT on your animal. Every website that you link needs to be read in its entirety by you. You should know the facts it tells. Expect me to quiz you on any links you include.

5. Do not copy & paste information. Read what a website says about your animal. Then, put it into your own words. I can easily tell the difference between how you speak and how website authors speak.

6. If you find coloring pages or fun games about your animal, be sure that they're appropriate for other students to do. Make sure that there are not any immodest advertisements on the page or images in the game. If there is a lot of violence in the game, then it isn't appropriate to post on my website. I will delete any games that I find inappropriate. If you're uncertain about a game, then ask me before posting it to your page.

7. Use my page as a guide for what you should do.
