Silent Signals Short Answer

Barracudas do not communicate with songs or calls, but they still send clear messages to one another. This passage explains how barracudas rely on body position, sudden movements, open mouths, and visual signals to warn other fish or defend territory. Readers also learn how their excellent eyesight allows them to observe the behavior of prey and other barracudas closely. Even though these fish are often solitary, communication still plays an important role when they hunt, interact, or protect a feeding area.

This worksheet helps students practice interpreting behavior and making inferences from details in the text. They learn that communication can take many forms and that actions can carry meaning even without sound. Vocabulary related to body language, territory, dominance, visual signals, and behavior strengthens both science knowledge and reading comprehension. It is also a useful passage for encouraging students to explain what an action means instead of simply identifying that the action happened.
