Researchers have discovered that the lionfish, a predator with venomous spines, has invaded Caribbean coral reefs and is eating native species. Ember gobies school together in massed of about 100 fish - starkly different behavior from most gobies that hide alone in holes or cracks in the reef, making the new species an easy target for lionfish attacks.

They've gone on about 150 dives to Caribbean reefs using a 6.5-ton submarine with two robotic arms that stun fish for capturing by spraying them with water or an anesthetic, collecting them using a vacuum hose.
