A prehistoric dragon patrols a lonely beach.
Predatory sharks stalk their prey on pristine reefs.
Alongside these iconic predators is another world every bit is fierce.
The undersea world of Indonesia's reef warriors.
Indonesia is the centre of the world's coral reef diversity.
More species exist here than in any comparable system on Earth.
Reef residents have developed special tactics to avoid predation.
Sea horse and pipe fish rely on camouflage, precisely matching their environment.
This sea crate's lethal bite deters most predators, a fact the banded snake eel uses to its advantage.
Fast-moving predators pursue food wherever they like, but on the sea floor creatures have devised different strategies to hunt and escape being hunted.
With fins like feet and a built-in fishing lure, the voracious frogfish uses camouflage for both defence and offence.
The diverse scorpion fish family also includes many ambush predators.
They gently sway as they move along the sandy bottom, disguising themselves as harmless debris.
When the opportunity arises, however, they are quick to strike.
The colourful rhinopias prefers to remain stationary, springing into action only when a victim comes within range.
Cardinal fish rely on the sharp spines of a sea urchin or stinging tentacles of an enemy for protection.
This patient scorpion fish combines stealth with lightning reflexes to defeat the cardinal strategy.
Lion fish opt for a more active approach to satisfy their insatiable appetites.
Stalking the reefs with impunity, their venomous dorsal spines discourage attackers while confusing their prey.
Ribbon eels use their quick reflexes and flexible bodies to snatch unsuspecting prey that wanders too close.
Flamboyant cuttlefish are among the most lethal reef warriors.
Highly intelligent, they have the ability to change the colour, pattern and even texture of their skin at a moment's notice as they actively hunt along the sea floor.
Larger broad club cuttlefish are more mobile and every bit as fierce.
Looking like an alien spacecraft, this cuttlefish uses its dazzling display to freeze its victim while it strikes, thus ending our look at Indonesia's reef warriors.
