[QUOTE="Poec54, post: 38503, member: 3524"] The number of eggs in a sac, the size of them when they hatch, and the sex ratios have been fine-tuned over thousands of years to fit individual habitats. In some species males have to travel for miles and a higher percentage of them are needed to offset the risks and loss of males to predators and hazards. In others, a group of females may live close to each other, even within a few feet, so one male can easily impregnate a number of females. In those species, a 50/50 ratio means a lot of males go to waste. Humans don't have a 50/50 sex ratio at birth, so there's no reason to expect spiders to. Most tarantulas probably have sacs of 50-150 eggs, but again, there's different survival strategies. Is a small number of large slings best, or a large number of tiny slings? [/QUOTE]
