9pm NOVA - Ocean Invaders - Science
Marine biologist Danni Washington studies how lionfish have invaded the Atlantic and wreaked havoc, and what can be done about it.
NOVA “Ocean Invaders” explores the fascinating rise of invasive species in a globalized world where human activity has become an increasingly powerful evolutionary force. It dives deep into understanding one massively destructive species that has taken our oceans by storm — the lionfish. Native to the South Pacific and Indian Oceans and long prized in home aquariums, lionfish have invaded the Atlantic, and are now one of the ocean’s most successful invasive species, wreaking havoc in waters across the globe.
