The lionfish has tall, thin fins and red stripes that look beautiful. But they are highly toxic and are considered to be an invasive alien species in the United States because they swallow local fish that sustain coral reefs and cause coral reefs to be destroyed. There is a recent argument that lionfish can only survive in seawater and fresh water with high salt content. A sixth-grade student conducted a scientific project to prove that this view is incorrect.
As early as 2012, Arlington, a student of Florida who was only 12 years old, identified her research project in scientific experiments in the school. She discovered that lionfish thrived in low-level salinity fresh water. Her simple experiment was to capture the lionfish in the local lagoon, place them in a separate aquarium and gradually reduce the salinity content and record it.
Arlington found that even at very low salinity levels, lionfish can still grow healthily. Her experiments attracted the attention of adults. Researchers from the University of Florida and North Carolina continue to perform research to confirm and expand Arlington's results. Studies show that Lionfish can survive in the estuary. Arlington’s project has a history of One of the most influential sixth-grade science projects
