Osteichthyes!

We have 11 new friends in our class that will be helping us with our lab this week. They're comet goldfish, Carassius auratus. We will be investigating the effect of temperature on the rate of opercular opening. The operculum is the flap that covers the gills, and allows fish to fill up their mouths with water and
then push it out over their gills. Fun times! Osteichthyes is the scientific name for the bony fish,
to contrast with chondricthyes, which are things that swim but have skeletons made out

"Fishy I,Fishy II, Fishy III...and so on. Help us out! Also...note the sunken pirate ship in the
lower left corner...ARRR...
