Fishes

Hey Blogger fans! This week we are studying fishes. Weird fact too, if you have many fish of the same species the plural tense is fish, if they are many fish of the same species, then use fishes! On the first day we did a dissection. There were lingcod, rockfish, and greenlings. I chose a China Rockfish, which was great until we had to remove the otoliths! Otoliths are these small bony plates inside the fishes ears. You have to saw half way through the fishes skull and then bend it over like a hinge to remove them!!! Once they are out you can break them in half, heat them over a flame, and them put them under a microscope. By counting the rings on the burnt otolith you can tell how old the fish actually is (just like a tree, but a little more grusome!).
