Researchers have uncovered an under the sea phenomenon where coral-destroying crown-of-thorns starfish larvae have been feasting on blue-green algae bacteria known as ‘sea sawdust’.
The team of marine scientists from The University of Queensland and Southern Cross University found crown-of-thorns starfish (COTS) larvae grow and thrive when raised on an exclusive diet of Trichodesmium – a bacteria that often floats on the ocean’s surface in large slicks.
