Here are some general guidelines for baking salmon. 1  A good rule of thumb is that at 350 degrees the salmon will bake about ten minutes per one inch thickness of your fillet. 2  A two-inch thick fillet will bake for 20 minutes. 3  A 1-1/2 filet will take 15 minutes and so on.
In the United States, there are over 230 amphibians, over 280 reptiles and approximately 800 species of fish. Each of these categories has species represented on the US Endangered Species List. Together, more than 170 amphibian, reptile and fish species are threatened or endangered.
The answer to this question is-nobody knows! Scientists who study animal life are called zoologosts. They have recorded 20,000 species of fish, 6,000 species of reptiles, 9,000 birds, 1,000 amphibians, and 15,000 species of mammals. And, although there are a million named species of insects, scientists estimate that there could be another million waiting to be discovered and named!
