Underwater Signals Multiple Choices

Catfish may live in dark or muddy water, but they still have several effective ways to communicate. This passage explains how different species use sounds, vibrations, body movements, and chemical signals to interact with one another. Readers learn that barbels can help catfish detect changes in the water, while certain movements may warn other fish, establish territory, or play a role during mating. The reading shows that communication does not always depend on sight and can be especially important in environments where visibility is limited.

This worksheet encourages students to make inferences by connecting behaviors and signals with their possible meanings. They practice identifying examples, explaining cause and effect, and recognizing how an animal’s environment can shape the way it communicates. Vocabulary related to vibrations, signals, territory, senses, and behavior grows naturally through the passage. It’s a strong reading for helping students think beyond spoken language and understand the many ways animals share information.
