Venomous Invader Multiple Choices

Lionfish are beautiful fish with bold stripes, flowing fins, and a dramatic appearance, but this passage shows students that there is much more to them than their looks. Readers learn that lionfish originally come from the warm waters of the Pacific and Indian Oceans and that they are skilled predators that hunt small fish, shrimp, and crabs. The passage also explains how their venomous spines protect them from larger predators and why lionfish have become a serious invasive species in places such as the Atlantic Ocean and Caribbean Sea. Students see how one animal can be both fascinating and harmful depending on where it lives.

This worksheet helps students practice identifying main ideas and supporting details while also introducing the concept of invasive species. They work with cause-and-effect relationships as they connect the spread of lionfish with changes in coral reef ecosystems. Vocabulary related to predators, venom, invasive species, habitats, and ecosystems develops naturally through the reading. It’s a strong opening passage because it gives students a broad understanding of lionfish while setting up many of the ideas explored in the rest of the collection.
