        Killer Robots Battle Invasive Species: Lesson Plan | PBS NewsHour

        Indo-Pacific lionfish, believed to have been imported as aquarium pets in the 80s and 90s, are attacking coral reefs. The result is an invasive species that has extended its range to Brazil and is eating its way through local fish populations, changing the reef ecology. In this lesson, students will develop an understanding of invasive species beyond a simple definition and explore the science behind the concept.
