A couple of days ago I had to dissect a crayfish.It was a mouth watering experience however during this procedure we has to find different part of the cray fish (which is a arthropod) such as the dorsal view which is is the back of the crayfish, the ventral view which is the front of the crayfish, the mouth parts and the side view. In this dissection we had to find the posterior or anterior for our arthropod. We had to label and proximal (which is to describe the location of a part.) During this project we had to cut open the crayfish on the ventral view. Inside of the cray fish I spotted many features such as the heart and all of it's organs. But in order for a cray fish adaptation it had to have different features of its body. In these pictures above you see the side view and the mouth parts. As can you see in the pictures I labeled the antenna because that is a big feature of a crayfish because with out they antenna's they love the sense which is also one of their organs to locate. The following picture above shows the crayfish on the side view it shows the cheliped and the cheliped is important as well because with out a cheliped how would the crayfish ever eat and catch its prey.
During this project I have learned how to use a scalpel which is a special dissecting knife to cut through flesh.(Yes!It does work.) I learned that when you use a scalpel you have to be care full before you cut through the organs of and animal. In the beginning of this project I was very disgusted with the smell and the way the arthropod looks but I have learned to go in to depths with this animal and just look at all the interesting parts and different locations of this arthropod. I was always puzzled with questions such as; Do arthropod have white blood cells that fight bacteria just like we do? Do all arthropods have four legs and is an ex-so skeleton? All these amazing questions cant wait to see what what is the answer to my question.
