Ocean Invaders

Lionfish–long prized in home aquariums–have invaded the Atlantic, and are now one of the ocean’s most successful invasive species, wreaking havoc in waters across the globe. Join ocean explorer Danni Washington on a journey to find out how they took over, why they’re doing so much damage, and what can be done about it.

Without any natural predators, invasive lionfish populations grow unchecked and wreak havoc on marine ecosystems. Watch free divers hunt these poisonous fish.

Non-native species, like cats and honeybees, can either become naturalized, as a part of the ecosystem, or invasive and disrupt the ecosystem.
