Sometimes I feel like I'm living a real-life series of Seinfeld episodes. Those situations range from things that actually happened on Seinfeld to things that would have made excellent Seinfeld episodes... I call those the Seinfeld episodes that never were but probably should have been. One of those episodes actually happened shortly after I moved into my condo last year.
As long as I can remember, I have always been interested in insects, arachnids and other creepy crawly things that most people find repulsive. I own a rosy-haired tarantula, named Rosie, and during the year, she is usually in my classroom. The kids love watching her and she is a huge topic of conversation. During the summer, I bring her home and keep her in the basement in a tank. Shortly after moving in, my neighbor Chris and I got to talking. The topic of the tarantula came up, and he asked if he could come over and see her. Cool... Chris came over and so did his daughter, my daughters and another one of our neighbors. We all traipsed into the basement and over to the tarantula tank. I peeked in. No spider. I told him to hold on for a second. I lifted the lid and peered inside. She wasn't on the top of the cage. Oh, shit... I thought to myself, and a sinking feeling began to seep through my body. I lifted a log tunnel that was in the cage. No spider. I turned around and looked Chris in the eyes. "I... I... I don't know what to say to you. The spider's not here!"
All of a sudden, he turned on a dime. "Chris! Where are you going?" I shouted. He spun around and stopped... for only a second. "Why, I'm leaving!" he exclaimed. He made a quarter turned and almost knocked all of the children down as he made a beeline for the staircase. "But CHRRRISSSSSSSSS!" I exclaimed. "Aren't you going to help me find her?" By now he was halfway up the stairs and he had left a huddle of crying children in his wake. He bent down and spoke to me through the balusters. "Nope! I'm going home. I pushed past all of the children just like George in the fire episode and now I'm going home." he said. "What about the kids and the spider?" With that, there was no response and he was gone. I was left standing with a huddle of 4 children who quickly realized that Chris was gone... with that, they each turned on their heels and RAN up the stairs. Their shrieking could be heard all throughout the condo.
Here we go again, I thought to myself. This is not the first time that a tarantula of mine had escaped. It happened one other time about 14 years ago - my first tarantula, Chocolate Michelangelo had escaped in my kindergarten classroom, and my colleagues almost killed me on the spot! I got on the phone with my mother and told her what happened. She laughed. She clearly remembered the last time the spider escaped. As I was talking to her, I suddenly saw a tiny hint of a web that started at the tank and I followed it across the room with my eyes. Please, please, please... I whispered to myself. Please just be there... somewhere... let me find that spider! I knew if I didn't find her immediately, my daughters wouldn't sleep until I found her. I was still on the phone with my mom. I was giving her the play-by-play on finding the spider. The web ended and I ducked down. BINGO! There she was - on a concrete wall under a piece of wood framing. I got a container and gently guided her inside. No, I don't handle her, and I have good reason to.
You see, when I got my first tarantula 16 years ago, I actually got three. One was for the security guard, one was for the biology teacher upstairs and one was for me. I was so excited to own my first tarantula. The spiders came in Petri dishes. I have since found out that the animals that come from biological supply houses are not necessarily treated in the best way. Needless to say, the trip from North Carolina to Connecticut in a Petri dish packed in a box full of those little styrofoam pellets must have been a rough one. I chose the largest spider. I opened up the Petri dish, and reached my hand in to touch the spider... the damn thing reared up on TWO legs. I almost wet myself. I also didn't know at the time, that tarantulas have incredible jumping power. Thank goodness it didn't jump on me because I would have died on the spot. I quickly closed the Petri dish and reached for the smaller tarantula. The kids named him Chocolate (because he was chocolate brown) Michelangelo (after the Teenage Mutant Ninja Turtle - not the artist. LOL!) Anyhow, I digress. Chocolate Michelangelo molted several times, and I never saw it happen. My mom was always spider sitting when he did. He eventually died and I was spiderless for 8 years or so. Fast forward to Rosie...
Spiders don't have skeletons like we do. They have something called an exoskeleton. It's basically a skeleton on the outside of their body. The exoskeleton is partially made up of a material called chitin, which is a super strong substance. In order for the spider to grow, the exoskeleton has to be shed - and a new exoskeleton takes its place. It is kind of like when a snake sheds its skin... The spider spins an elaborate web, lies on that web upside down and then waits. The waiting is the crazy part. It can take the tarantula up to 12 hours to complete a molt. The first time Rosie molted, I was lucky enough to have witnessed the actual molting process. It was amazing! I had her in school at the time, and I wondered why she had refused food. When I came in the next day, she was upside down on the most beautiful web I had ever seen. Oh. I thought she was dead. It really looked like she had spun a death bed! I left the room and went to a staff breakfast. When I came back, I looked closely at the "death bed" web. All of a sudden I noticed that her legs twitched. What the... I stood still, held my breath and watched. She wasn't dead! She was molting! I was so excited... like a 5 year old! She molted, I got to watch the whole thing, and I took pictures.
Rosie molted again starting on the night before Halloween and finishing up sometime early on Halloween. I didn't get to watch it this time. Basically, the spider will lie in its cradle, most often on its back. It is vitally important that the tarantula not be disturbed during this period, for shedding is a stressful activity that consumes every ounce of its energy.
The tarantula will pump fluid pressure in its body to get the carapace to pop off first. The abdomen will split along its sides, and the spider will continue to slowly, pump fluid in its limbs to shed the old skin off its legs. This process takes a long time and leaves the spider in a defenseless and vulnerable position, even after the old skin has been shed. The body is actually soft until the exoskeleton dries and becomes a sort of armor for the spider.
I realize that this blog is probably WTMI - Way too much information, but I did have a few inquiring minds out there, and so I decided to answer them with this blog.
Ready To Molt
Here is Rosie laying on a gossamer web that she has spun - a molting web. Those shiny black things are her fangs.
Molting 1
Rosie's new body is on the bottom. She looks much darker because she is wet. Notice how her fangs are white. She is busy trying to free her legs from the old exoskeleton.
Seeing Double
Rosie is now free from the old exoskeleton. Her new body is jet black on the underside. She is still wet and very fragile. Her exoskeleton needs time to dry and harden. She is still upside down. Her molting web cradles and protects her.
Rosie - Post Molting
This is a picture of Rosie after she has molted. Notice how her carapace is a metalic rose color... and her hairs have dried to a nice brown.
Skin- Post Molting
This is a picture of the tarantula skin post-molting. There are 10 openings. Eight are for legs and the top two (at 12 O'clock are for the fangs). Those two little lines at 6 O'clock are the spinnerettes. That is where she spins her web from. Each foot has a little hook on it. The little hooks allow Rosie to climb up walls. She can even climb the lucite walls of her cage!
