This document discusses fish and shellfish. It begins by defining fish and shellfish as seafood obtained from various bodies of water. While the edible flesh is similar to meat, fish and shellfish cook more quickly than meat due to less connective tissue. The main differences between fish and shellfish are that fish have fins and internal bones, while shellfish have hard outer shells and no internal bones. Fish are also classified based on where they come from, their physical shape, and fat content. The document provides examples of round fish like salmon and carp fish, as well as flat fish including flounder and sole.
