Fun spider lessons for explorers ages 4–10. Best enjoyed with a grown-up!
Jumping spiders are small spiders with big eyes. Instead of waiting in a web, they walk around, look carefully, and jump!
Did you know? There are more than 6,000 kinds of jumping spiders in the world.
Grown-up note: Jumping spiders belong to the family Salticidae, the largest spider family.
Yes! All spiders have eight legs. Jumping spiders use them to walk, climb, and jump.
Did you know? Near their mouth, spiders also have two small 'arms' called pedipalps. They aren't legs!
Grown-up note: Pedipalps are often mistaken for an extra pair of legs.
Jumping spiders have eight eyes. The two big ones in front see sharp details. The others help them notice movement all around.
Did you know? Their big front eyes work a bit like tiny binoculars.
Grown-up note: Not every spider has eight eyes, but jumping spiders do.
Nope! Insects have six legs and three body parts. Spiders have eight legs and two body parts. Spiders are arachnids.
Did you know? Scorpions and ticks are arachnids too!
Grown-up note: The two spider body parts are the cephalothorax and the abdomen.
They jump to catch food, to get from one place to another, and to escape danger.
Did you know? Before jumping, they usually attach a silk safety line.
Grown-up note: Jumps are powered partly by hydraulic pressure in the legs.
Jumping spiders spin a cozy little silk pocket, often called a hammock. They rest, sleep, and molt inside it.
Did you know? Some spiders hide in their hammock for days before a molt.
Grown-up note: It's best not to disturb a spider in its hammock, especially near a molt.
Spiders wear their skeleton on the outside! To grow, they wiggle out of their old skin and grow a new one.
Did you know? The old skin left behind is called a molt or exuvia.
Grown-up note: Molting is a vulnerable time. Avoid feeding or handling during it.
Before a jump, a jumping spider sticks a silk thread behind it. If it misses, it can climb back up!
Did you know? This silk line is often called a dragline.
Grown-up note: Draglines are one of several silk types spiders produce.
Jumping spiders spot their food with their super eyes, sneak closer slowly, then pounce!
Did you know? They can plan a route around objects to reach their target.
Grown-up note: Their vision is among the best of any spider.
Jumping spiders rest at night, often tucked into their hammocks. Scientists have even seen signs of something like sleep!
Did you know? Some studies have seen their legs twitch during nighttime rest.
Grown-up note: Research on spider 'sleep' is still ongoing.
Pet jumping spiders eat small live bugs, like fruit flies or small crickets, that are the right size for them.
Did you know? Prey should usually be about the size of the spider's body or smaller.
Grown-up note: Feeding is always done by an adult.
They sip tiny water droplets! A light mist on the side of the enclosure gives them a drink.
Did you know? A big puddle can be dangerous for a tiny spider.
Grown-up note: Mist lightly; avoid soaking the enclosure or the spider directly.
A good home has fresh air, a secure lid, things to climb, and enough room to explore.
Did you know? Jumping spiders often like to build near the top of their home.
Grown-up note: Ventilation and a secure, escape-proof lid are essential.
Jumping spiders love to climb and explore. Sticks, plants, and branches give them places to perch and play.
Did you know? In nature, many jumping spiders live on plants, fences, and walls.
Grown-up note: Clean, secure decor reduces fall risk.
Jumping spiders like to live alone. If they share a home, they might fight or even eat each other.
Did you know? Each of our spoods has its very own home!
Grown-up note: House each spider separately.
Some bugs, like crickets and mealworms, can bite or bother a spider, especially while it's molting. Grown-ups remove uneaten food.
Did you know? A molting spider can't defend itself well.
Grown-up note: Remove uneaten live prey promptly.
When we find a spider outside, we look with our eyes and let it keep doing its job in nature.
Did you know? Spiders help keep bug numbers in balance.
Grown-up note: Teach children to observe, not handle, wild animals.
Spiders are tiny and fragile. Grabbing or squeezing can hurt them.
Did you know? Even a short fall can hurt a spider.
Grown-up note: Any handling should be adult-led and minimal.
Pet spiders are taken care of by grown-ups. Kids can help watch and learn with an adult nearby.
Did you know? In our house, Mom handles all the spider care.
Grown-up note: Supervision protects both children and animals.
A spider from somewhere else might not belong in your backyard. Grown-ups check where it came from and the local rules first.
Did you know? Animals can cause problems in places they don't naturally live.
Grown-up note: Never release captive-bred or non-native animals; check local regulations.
Every creature has a home. We leave rocks, plants, and webs the way we found them.
Did you know? Many tiny creatures hide under leaves and rocks.
Grown-up note: Model 'leave no trace' habits.
Mother spiders wrap their eggs in a silk sac to keep them safe.
Did you know? One egg sac can hold many eggs.
Grown-up note: Some mothers guard their egg sacs.
Baby spiders are called spiderlings. They look like tiny versions of grown-up spiders!
Did you know? Spiderlings can be smaller than a grain of rice.
Grown-up note: Spiderlings disperse after hatching.
As spiderlings grow, they become juveniles. They keep molting to get bigger.
Did you know? Keepers often write 'i6' to mean a spider's 6th stage, or instar.
Grown-up note: Bella was sold as an i6 juvenile.
Each time a spider molts, it gets a little bigger. Then the new skin hardens.
Did you know? Colors and patterns can change after a molt!
Grown-up note: We saw Spider Spider Man's spot change color after a molt (our observation).
After their final molt, spiders are grown-ups. Grown-up spiders don't molt anymore.
Did you know? Many jumping spiders live about one to two years.
Grown-up note: Lifespan varies by species and conditions.
Egg → spiderling → juvenile → adult. That's the spider life cycle!
Did you know? Spiderlings don't have a 'larva' stage like butterflies.
Grown-up note: Spiders develop directly without metamorphosis.
Lessons share general science about jumping spiders. Anything about Xander's own spiders is a family observation, not a scientific finding. Species care varies, so please consult reputable sources.
