This document discusses fish anatomy and morphology. It describes the different types of fins found on fish, including dorsal, pectoral, pelvic, anal, and caudal fins, and explains their functions in movement and stabilization. It also outlines various fish body shapes such as fusiform, sagitiform, and anguilliform, and how these shapes aid in swimming, hiding, and maneuverability. The document provides instructions for the Japanese art of fish printing called gyotaku and an activity where students can build their own fictional "frankenfish" by combining different fish parts.
