n a far corner of south-east Asia
lies the Coral Triangle,
a cluster of the richest coral reefs in the world.
Undersea cities crammed full of life.
As in any crowded metropolis,
there is fierce rivalry for space,
for food
and for a partner.
But the reef is also a place full of opportunity.
A cuttlefish.
It specialises in hunting crabs.
But a large crab is a dangerous quarry.
It has powerful claws.
The cuttlefish, however, has a remarkable talent.
Its skin contains millions of pigment cells
with which it can create ever-changing colours and patterns.
And that, apparently, hypnotises the crab.
A cuttlefish may be clever,
but a shark is bigger.
And it eats cuttlefish.
Time to disappear.
Back to the hunt.
A new target, but the same mesmerising technique.
For those that manage to establish themselves
in these bustling undersea cities,
there can be great rewards.
