Sharks do not have mammary glands, and do not feed their young, so are therefore disqualified from being named mammals. Sharks use gills to breath with, as fish do, rather than lungs that exchange respiratory gases. No, sharks are not mammals, but actually fall under the category, or class, of fish.
