Built to Hunt

This passage takes a closer look at the physical features that make barracudas such effective predators. Students learn about their long, torpedo-shaped bodies, powerful jaws, razor-sharp teeth, large eyes, and silvery coloring. The reading explains how these features help barracudas swim quickly, see well in changing light, hold slippery prey, and remain less noticeable in the water. It gives students a clear picture of how an animal’s body can be specially suited to the job it needs to do in its environment.

Reading a passage like this helps students practice connecting physical structures with their functions. They work on descriptive comprehension by sorting through details and deciding why each feature matters. Vocabulary related to anatomy, movement, hunting, and adaptation grows naturally through context. This is also a good passage for helping students move beyond simply stating what an animal looks like and begin explaining how its appearance supports survival.
