Spiders are arachnids, not insects, and they have eight legs.

Spiders make silk from special organs called spinnerets.

Spider silk is one of the strongest natural fibers for its thickness.

Not all spiders spin webs to catch food. Some, like jumping spiders, hunt their prey.

Most spiders are harmless to people, and they help by eating many insects.

Bats are the only mammals that can truly fly.

Many bats use echolocation, which means they find their way by listening to echoes of their own calls.

The pointed black hat became the classic witch look through book illustrations and movies, including The Wizard of Oz (1939).

Pumpkins are about 90% water, and botanically they are a fruit.

Jack-o’-lanterns come from an Irish tradition of carving turnips. Pumpkins became the choice in America because they were easier to carve.
