We are all rather fond of Harriet here at the Nature Museum. She is a very large, female Striped Knee Tarantula who has been with the institution longer than pretty much everyone. She has been here so long that I have never actually been able to find any record of where she came from or when. In spite of her somewhat intimidating appearance she is a very gentle creature and also quite a celebrity. She has featured on a blues album cover.
She has done numerous TV appearances for various local stations and she also appeared on the cover of a medical paper about treating arachnophobia.
But in between all this jet setting she is just a regular arachnid. She spends most of her time in the Istock family Look-in-Lab raising squeals from countless children.
Once in a while we will notice that she starts to slowly spin a thick web mat and then we know exactly what she is up to. She is getting ready to shed.
The first time she did this after I started working here I was alone in the lab one evening, I have to confess I had never seen a tarantula shed before so imagine my horror when I walked past her tank and she was laying upside down with all her legs in the air! Absolutely no prizes for guessing what I thought. I was so upset and spent most of that night imagining having to tell everyone that dear, sweet Harriet was no more. When I came in the next morning there appeared to be TWO tarantulas in Harriets’ cage, and they were both the right way up. By now I had begun to put two and two together, or in this case, one and one and realized what had happened, Harriet had shed. I have been here for several years now and after the trauma of that first time I made a little sign which reads ‘She’s not dead, she’s shedding!’ I have witnessed numerous Harriet sheds and each time I marvel at the process. Here is Harriet the morning after her most recent shed.
She is the one on the right of the picture! And here is her freshly shed skin, called an exuvium.
If you look closely you can see each individual hole where she carefully pulled her legs out of the old skin.
Now even if you are not keen on spiders, you have to admit, that is pretty cool!
