How do spiders give birth?

Female spiders lay their eggs inside an egg sac which looks like a cocoon. It depends on the species, but there could be hundreds of eggs. The egg sac, like a spider's web, is made of silken thread. Some females carry their sacs - in their jaws or on their spinnerets - until the eggs hatch.

They go everywhere with her, including hunting.

How do spiders get pregnant?

Both the male and female reproductive organs are at the rear of the abdomen, but spiders don't mate by coupling these organs.

Can a female spider lay eggs without a male?

Yes they do produce unfertilised eggs, although I've never kept tarantulas so cant speak for them, other spiders I've kept have. If she's never been in contact with a male then it's probably safe to assume they'll be unfertilised.

Why do female spiders eat males after mating?

Turns out the motivation for this creepy cannibalism is much simpler. It's all about size. If males are small, they're easier to catch and therefore more likely to be prey, say Shawn Wilder and Ann Rypstra from Miami University in Ohio. Big females eat their puny mates simply because a) they're hungry and b) they can.

Some male spiders do know!

Some males know that they can be consumed by their mates and have evolved a defense mechanism to protect themselves against cannibalism.

Each male can consequently only mate twice in their entire lives, but, if they survive the first encounter (a female will usually eat the male if mating continues to long) they can then chose to either mate with her again or to find a different female to mate with.

How many times do spiders mate?

Females of some species mate only once, whereas others mate several times with the same male or mate with several different males. The long-lived females of mygalomorph spiders must mate repeatedly because they shed their skins once or twice a year, including the lining of the spermathecae.

Does killing a spider attract more?

No, dead spiders won't attract other spiders. At least not directly, but it might indirectly as their carcass can turn into food for other insects and attract other spiders to eat said insects.

How many babies can a spider have?

Spiders will lay between 2 and 1,000 eggs, depending on the species. Almost all female spiders protect their eggs by making a silk 'bed' and then covering them with a silk 'blanket'. She then wraps them in more silk to make the egg sac. She hangs the sac somewhere safe and guards it until the babies hatch.

How long does a spider live?

The life spans of spiders vary considerably from species to species. While many common house spiders live a few years some can survive up to seven years. Tarantulas, on the other hand, can live into their 20s. The arachnid with the longest known lifespan prior to Number 16 was a 28-year-old tarantula found in Mexico.
