No spiders have wings for flying but many spiders have a special way of moving through the air.
All spiders can make a very thin but very strong silky thread. They sometimes escape from danger by dropping down quickly as they make silk behind them.
Many spiders make large webs with their silk. The webs act like big nets that can catch flying insects that spiders like to eat.
The web silk is very sticky so insects that touch it become trapped.
When the spider feels the movements of the insect trying to get free, it rushes in to wrap the insect with more silk.
Spiders all have venom that they can inject with their fangs to quickly kill their prey.
All spiders are carnivores, which means they only eat animals. They never eat plants. All spiders are predators, which means they catch and kill the animals they eat. The animals that predators catch are all called prey.
Some people get afraid whenever they see a spider, but spiders will never attack a person.
Most spiders’ venom is only strong enough to kill an insect but there a few spiders that have powerful venom that can hurt people. Black Widow spider Brown Recluse spider
