My Black Widow Spider's egg case hatched, releasing hundreds of tiny babies. While prey animals tend to have lots of offspring, most predators tend to have relatively few offspring. Why do spiders have so many babies?
Answer:
Many of the babies are eaten by predators, but even more of them are eaten by their brothers and sisters. There are not usually swarms of tiny insects around a newly hatched egg case, so the hungry baby spiders eat each other. Those that are the fastest and strongest survive, and the others provide a quick snack for them.
