00:00Across the African savannah, this cave buffalo is enduring an assault from hundreds of blood-sucking ticks.
00:09Ticks are clustered around its ears, the base of its horns, its neck, shoulders and deep folds of skin,
00:17while swarms of flies constantly buzz around its eyes and nostrils, making every moment miserable.
00:26It has tried everything.
00:30Shaking its head.
00:33Flicking its ears.
00:38Rubbing against tree trunks.
00:43Rolling across the dusty ground.
00:48But the ticks refuse to let go.
01:05Finally, the buffalo walks into a river.
01:12As the water rises to its belly, the first small fish begin to appear.
01:19Within just a few minutes, a dense school of fish surrounds every part of its body beneath the surface.
01:31From its belly and groin to its thighs, knees and even its hooves, almost no exposed skin is left untouched.
01:52Hundreds of fish press their mouths against the buffalo's body, carefully searching every fold of thick skin for parasites.
02:05As soon as one fish moves away, another immediately takes its place.
02:15Together, they move like a living carpet covering the buffalo's lower body.
02:22Where ticks are most concentrated, several fish crowd into the same spot, pecking and pulling at parasites that cling tightly
02:30to the skin.
02:40Meanwhile, above the surface, red-billed ox-peckers begin to arrive.
02:54They land on the buffalo's horns, shoulders and back, before quickly moving toward the areas with the heaviest tick infestations.
03:06Their slender bills probe deep into the ear folds, around the horn bases and through the wrinkles of the neck
03:13and shoulders.
03:16With every precise peck, another tick is removed.
03:22The birds work rapidly.
03:26The moment one tick is swallowed, they step to the next spot, searching for more hidden parasites.
03:42Beneath the water, the fish never stop working.
03:48They constantly change positions, covering everything from the buffalo's belly down to its legs.
03:57Inspecting every patch of skin, every wrinkle, and every layer of soft mud still clinging to its body.
04:31The birds are constantly changing.
04:33As you can see the birds, the birds are cleaning the floe.
04:34They lift the birds, which are cleaning their pits, things are cleaning.
04:34cannot reach.
04:42Two completely different species are cleaning the buffalo at the same time.
05:25After only a short while, the number of ticks has dropped dramatically.
05:31The buffalo no longer shakes its head over and over. Its ears stop twitching so violently.
05:41It stands quietly in the river, its eyes half closed, breathing slowly,
05:47barely reacting to the flies still circling overhead.
05:53For the fish, this is a nutritious meal.
05:56For the red-billed oxpeckers, it is another familiar source of food.
06:06And for the buffalo, it is a mutually beneficial relationship
06:11that greatly reduces the burden of parasites.
06:19In nature, survival is not always built on conflict.
06:26Sometimes it depends on simple partnerships that benefit every species involved.
06:37Here in the rivers of the African savannah, each creature plays its own part in keeping the
06:43ecosystem in balance.
07:08Earth of the sea.
07:11So,
07:23Let's go.
