I was extremely pleased to take this photo today. What is it?
This week my pet tarantula molted for the first time since I got it at Christmas. The first molt for a new pet spider is important, because it is a good indication that you have things set up properly. This is a close-up shot of the inside, showing where all of the legs enter the prosoma, the front part of the spider's body. For a wider view, take a look at Science Photo #837.
