00:00Southeast Sri Lanka.
00:08It's the middle of the dry season.
00:13This is the only remaining waterhole for miles around.
00:23Mugger crocodiles.
00:26Chives five meters long.
00:30This male has been traveling for hours.
00:37The waterhole is the only place where he has a chance to catch a deer.
00:49A single adult would be enough to feed him for the entire dry season.
00:55But hunting prey that knows you're here requires something truly remarkable.
01:07He creates... a trap.
01:18He digs down into the mud.
01:25Deep enough to hide beneath the vegetation.
01:29Perfect camouflage.
01:47He has built his trap right on the water's edge.
01:50So it's the first place that thirsty deer will come to drink.
01:56The waterhole will come to drink.
01:57The waterhole will come to drink.
02:03Let's go.
02:33Let's go.
03:03Let's go.
