Jumping Spider Dances: Gamete Size and Resource Allocation
Because sperm are tiny and eggs are relatively large, it takes much more to make an egg than a sperm.
With the same amount of resources a female jumping spider needs to produce two eggs, a male jumping spider can produce two thousand sperm.
If the goal is to have as many offspring as possible, the female can accomplish this goal by mating once per breeding season. The male, however, can have more and more offspring with each mating.
