Download PDF Why Do Fish Have So Many Different Shapes?
Fish body shapes are closely tied to how they move and live. Streamlined fish such as tuna have efficient open-water shapes, while laterally compressed fish such as angelfish have tall, narrow profiles. Pufferfish have rounded bodies and can inflate when threatened.
Those differences are easy to spot in this collection: compare the long fins of the betta, the tall angelfish, the round pufferfish, the whisker-like barbels of the catfish, and the streamlined trout, salmon, and tuna.
