 This week we learned about different types of fish and their classification. The different types of

major fish group class agntha, chondrichthyes, and osteichthyes. We learned about the

differences between all the types of fish groups. We also learned how they swim, eat, digest etc.

We dissected a bony fish or class type osteichthyes. When we first opened up the fish we had a

bunch of meat. The first thing we saw were the ribs on top. As we dug deeper we found the

intestines, stomach lining, and the testes. We knew the fish we had was male because the

testes were more white, while females have a more pink lighter color. Under the gonads we

found the intestines and other organs. We also found the liver which was a dark brown reddish

color. When we cut open the gill cover we found the heart. The fins at the bottom and on the side were the pectoral fins.
