The Tale of Two Spiders- MM

There were two spiders present in the small plastic container, one much larger in size (at least quadruple) than the other. In most species of spiders, the females are generally bigger than the males. In this scenario, the difference in size did not seem to be due to sex, rather to age. The smaller spider's abdomen was of a similar color and proportionally of similar size to the big spider, though its legs were much lighter in color and thinner. Both spiders' legs were folded in three sections, and contained two kneecap-like junctions. However, the larger spider's kneecaps possessed distinct coloration- the first set were white and the second set were black. Along with the size difference, this indicated the smaller spider to be- in the earlier developmental stages of legs- a young female or male, whereas the larger spider was an adult female.
