Crown-of-thorns starfish... coral killers.
长棘海星，珊瑚杀手
Climbing over their prey,

they secrete digestive juices that turn the inside of the coral to liquid.

Then they suck out the nutrients, leaving nothing behind but a ghostly skeleton.

Fortunately, coral has an unlikely ally... the Triton's trumpet.

Believe it or not, this is a predator on the prowl...

its killer pounce revealed only when time is speeded up.

An unlikely hero, perhaps.
