This is my pet spider Matilda, and her molted exoskeletons, so you can see how much she grows with each molt. For scale, each plastic dish is 3.5 inches (8.89 cm) across. Without looking it up, how large do you think this spider (Lasiodora parahybana) can get?
OK, the first thing to do is go get a ruler. Lasiodora parahybana is one of the three largest spiders in the world. Matilda is still a baby. When she is full grown, her leg span can be as much as eleven inches (28 cm). It will be years before Matilda gets that big, but I am enjoying watching her grow.
