TWIS #9

   My group and I had four new different specimens. We had choices either to dissect a frog or mouse- or a skate(related to a stingray) or perch(a fish). Theres four people in my group, and we had to pair up in two. My partner and I had dissect a skate and the opposite part of our group had chose to work on the perch. When we stabbed the skate's stomach. All we saw was oil and water OOZING out of it's belly. We had found the liver, stomach which we thought was a heart, and the lungs.

   From this experience with aquatic animals. I learned that the skate smells extremely bad when you get all the way inside of the animal. It has a smooth belly but a hard surface on the Dorsal view. It has lots of liver and it's stomach looks similar to a huge heart. We also learned that if you squeeze the skate's stomach, Green slimy particles comes out (Ewwww).
 
The differences that my I noticed from the skate and the perch, is that it can be a little difficult to cut through the perch. But for the skate, its nice and smooth. They both obviously have different ways to tell of what gender they are. The skate has lots of liver and it looks discusting. But the perch doesn't look revalting at all when you cut in. The thing we also noticed, is that when you cut into the skate. Oil and water comes out. When you cut into the perch, nothing oily or watery pores out.
