Blog #13 (Dissection)

Blog 13 What was most interesting about this week's dissections? 

The Crawfish i thought was interesting because it has such a hard exoskeleton and so many appendages. The exoskeleton was very similar to an exoskeleton that I would encounter on an insect. Also that the crawfish had exact symmetry with its organs,etc. you could cut the crawfish right down the middle and it can be the same on both sides. The gills on the crawfish are similar to the book lungs of an insect, this is further example that a insect an a crawfish are arthropods.
