You’re clambering through the bush on one of Indonesia’s Lesser Sunda Islands,
00:12
when you suddenly spy a Komodo dragon in the clearing ahead.
00:17
So, what should you do?
00:19
Are you doomed?
00:21
Forked tongue flickering; sharp, saw-like teeth glimmering;
00:25
and strong, scaly body stretching up to three meters,
00:30
Komodo dragons are formidable— and the world’s largest lizards.
00:36
They can weigh over 80 kilograms,
00:39
but that number fluctuates dramatically since they're capable
00:44
of gulping down 80% of their body weight in a single meal.
00:50
Komodo dragons are one of dozens of species of monitor lizard.
00:56
They evolved in Australia and now inhabit just a few Indonesian islands,
01:01
where adult komodos generally have no natural predators—
01:05
besides each other.
01:07
They begin their lives as limber, tree-dwelling hatchlings.
01:12
Within their first year,
01:13
they rarely venture to the ground in order to avoid predators,
01:17
like adult Komodo dragons.
01:19
Because cannibalism certainly isn’t out of the question.
01:23
Juveniles actively hunt insects and other lizards.
01:28
And once they grow larger, they graduate to the ground,
01:31
and their diet eventually shifts dramatically
01:35
to include animals several times their size.
01:39
They devour deer, pigs, and even water buffalo,
01:44
bones and all.
01:46
Komodos can lie in wait for hours alongside game trails.
01:50
But at the opportune moment, they’ll lunge,
01:53
and can reach 17-kilometer-per-hour bursts of speed.
01:58
Their extremely sharp teeth have serrated edges
02:02
and tips coated in iron that puncture and tear through flesh,
02:07
making their bites quite literally metal.
02:11
But exactly what komodos owe their hunting successes to—
02:15
especially when it comes to taking down larger animals like water buffalo—
02:21
has been debated for decades.
02:24
Back in the 80s, one researcher proposed that even if their prey initially escapes,
02:30
Komodo dragon saliva might store harmful bacteria,
02:34
which could proliferate in the bite wound and help kill the animal.
02:40
But researchers have since found that not all Komodo dragon saliva
02:45
packs such lethal bacteria.
02:47
And some bite wounds might get infected all on their own.
02:51
Interestingly, Komodo dragons also have venom glands,
02:56
which secrete anticoagulant and shock-causing compounds,
03:00
possibly exacerbating the destructive powers of their bites.
03:05
But it’s unclear whether venom is playing much of an active role.
03:10
And Komodos’ thrashing bites alone seem harmful enough
03:15
to cause fatal injury much of the time.
03:18
But they’re not just hunters; Komodo dragons are also scavengers.
03:23
With their characteristic undulating walk
03:26
and their snake-like flicking forked tongue,
03:29
they’re able to gauge the direction of different scents
03:32
and identify rotting flesh from afar.
03:36
When one Komodo takes down a water buffalo,
03:39
dozens may congregate to feed.
03:42
However, despite regularly diving into decaying corpses,
03:47
Komodo dragons rarely succumb to infections themselves—
03:52
even though males lead devastating wounds on each other during breeding season.
03:57
Researchers think this is because their blood is packed with peptides,
04:02
which are like small proteins,
04:04
many of which can fight microbes and stimulate the Komodo’s immune system.
04:10
Some of these antimicrobial peptides have proven so promising
04:15
they’re even being investigated for human antibiotic uses.
04:19
But how can you protect yourself in the land of dragons?
04:24
Komodo Island oral tradition holds that a woman long ago gave birth to twins,
04:30
one human and one dragon.
04:33
Inextricably connected from then on,
04:35
the relationship between humans and Komodo dragons
04:38
was to be governed by respect and coexistence
04:42
instead of fear and violence.
04:44
And indeed, Komodo dragons generally avoid humans—
04:48
unless something like rotting flesh is also on the menu.
04:52
If you encounter a Komodo, try to stay calm
04:56
and avoid sudden movements that could pique their curiosity.
04:59
You’re better off orienting yourself behind them or to their side.
05:04
If one gets close, you could grab a stick and push it against their shoulder
05:09
or hit their sensitive foreheads.
05:12
And in the rare event one chases you, try outrunning them, climbing a tree,
05:17
or jumping into the ocean—
05:19
because they can run fast over short distances,
05:22
but they’re no marathon runners.
05:24
And large Komodos can’t climb trees anymore and tend to avoid water.
05:30
It’s also worth noting that if you did end up in this situation,
05:34
it’s probably because you illegally ventured into a protected area
05:39
without an experienced guide.
05:41
So, better to just avoid doing that to begin with.
