Meisen The flat part at the end of her, just forward of her fluke is called a keel. I am not sure if that is te corect spelling of it, but it is pronounced the same. It seems like the larger animals in the ocean have them. A lot of the larger sharks do fo sure, along with tunas. The idea of the keel is to add strength to the body at its weakest point. Since the tail is moving the whole animal, if it didnt have the keel, there would be a greater of breaking itself at the weakest point when it has a short but powerful burst of speed. (Does all that make since, I am lookng at it and not sure that it does). Let me know if you need a further explination.
The unique thing about the tank she is in is, it is a tank within a tank basically. The water you see is 1 million gallons, there is another 250,000 you dont see. The best way to describe it is, if you take an egg and put it in a small box that is just large enough to hold the egg without breaking, and then filling all the spaces with water, that is what the tank is designed like. So with that said, there are no corners for her to get into, and any ot the rebarb(sp?) that is in the cement doesnt come into direct contact with the water she is in. The walls that you see when you are infron of the exhibit is actually the shell. The walls are made of over 1.6 million 1"X1" tiles. There is actually now talk of replacing these tiles as they are starting to think they are somewhat sharp. How they are sharp, I dont know. I dont know that the rebarb(sp?) theory was ever a fact, or just a theory. Any way you slice it, she doesnt seem to be effected by how the exhibit is set up at MBA.
invincible569 She doesnt relly have any swimming patterns, which is what we are going for, nor do any of the other sharks in there. The Galapagos was displaying some swimming patterns when they were in an exhibit that was too small for them. Then they were moved to the million gallon tank, and swimming patterns went away. All the sharks in the exhibit swim where ever they want, the other three tend to stay towards the bottom, the GWS is usually towards the top. The GWS usually swim in the top 20 feet of so, as that is where you will find most penipeds(sp) (sea lions, seal).
She does come out of the water as she is an agressive eater, but only about a foot or so of her. She looks just like the ones you see on tv, her eyes roll back, teeth come out. The ones that are coming all the way out of the water are eating seals more than likely. If the footage is cought naturally it is not a big deal as they natually feed like that, But if you are bating a GWS to do that for photography reasons, you can get a very large fine. I honestly dont know if she is the only kind of shark that does that. I know that there are some wahles that will come out of water, Orcas will beach themselves to get seals. As far as coming out of the water and up in the air, I am not sure, someone else may know that answer here...
Good news for that that are planning to come and visit MBA in the next year or so. Our head shark aquarist has said that she will be on display for 6 months to a year. They are thinking that she is growing about an inch a month, but that is unconfirmed. What, you want more good news, ok. We are going to actively look for another GWS this summer. Dont ask that question you just thought of, we will come to that bridge when we cross it. This move is in anticipation of continuing the research on GWS. Because we had so many people come through the doors this year, it has given us additional funding to do more research for this project.
