Fish

FISH!!! As you can see at the top of this page, this is all about fish you can find in most water sources in Pennsylvania, or other parts of the United States. 41% of all known fish species are freshwater fish, which can be found in lakes and streams throughout North America, preferably Pennsylvania. You may think "oh, what could we possibly need to know about these creatures". It is obvious that fish play some roll in the environment. Fish live off of insects and algae, you will hear about algae some time soon, but again, if we need other resources to control these (fish). But as invincible as they seem, they are fragile creatures. Scales are insanely important to fish, as they protect the body. If the scales are to come off, the non-filtered water would get into the body and kill it. "How can this occur?", you may ask. The main cause of this, is pollution. This can get into the gills and again, damage the scales. So now we know our roll in the environment with fish, so........... that's about it...... Amphibians is next, but if covered it already, then......................yeah...................
