Quelle influence a la lune sur les requins SHARK FESTIVAL
Transcript
00:00 If our hypothesis is true, it will be a first for all species of sharks.
00:04 Despite the 386,242 km separating us from our brilliant satellite,
00:16 the Moon shapes our environment.
00:19 Its orbit drives the flow and reflection of the tides
00:27 and influences the lives of millions of animals.
00:30 The phases of the Moon condition the coupling of the crabs.
00:36 The lunar light guides billions of plankton zoos during their migration across the ocean.
00:43 And its gravitational force acts on the behavior and reproduction of fish.
00:53 And yet, no link has ever been established between the forces of the Moon and the king of the oceans,
00:58 the shark.
01:00 We know that our satellite is very important for other marine animals,
01:07 but no link has ever been found between the different species of sharks and the phases of the Moon.
01:12 But Dr. Pelayo Salinas de León, from the Charles Darwin Foundation,
01:19 thinks that the secret life and migration of the unicorn hammerhead shark could be influenced by the Moon.
01:24 If our hypothesis is true, it will be a first for all species of sharks.
01:29 The unicorn hammerhead shark is one of the many migratory sharks in the world.
01:34 And if Pelayo is not mistaken about the trigger element of its migration,
01:38 this study could solve the mystery of the migration of other species.
01:44 To prove his theory, he is about to place beacons on gestation females
01:49 in order to follow them throughout their reproductive migration across the tropical Pacific Ocean.
01:53 An odyssey of some 4,000 kilometers.
01:57 If their movements correspond to the phases of the Moon,
02:03 our scientific understanding of sharks could be transformed forever.
02:11 The investigation begins 1,000 kilometers from the South American coast,
02:15 in an archipelago born in the fire.
02:18 The Galapagos Islands.
02:26 With a unique fauna in the world,
02:30 from blood-sucking birds to sea lions,
02:35 these islands have transformed our understanding of life on Earth.
02:41 This volcanic hot spot attracts an even more mysterious creature.
02:46 The unicorn hammerhead shark.
02:54 With its silhouette like no other,
02:58 these majestic sharks can reach 4 meters long and weigh up to 160 kilos.
03:08 We are here to prove that the full Moon of this month
03:11 triggers the incredible migration of pregnant females from the Galapagos
03:15 to nurseries located along the coasts of Central and South America.
03:20 And there is no better place to find these discrete animals than the Darwin and Wolff Islands.
03:32 The Darwin Island, or Darwin's Arch,
03:34 is the epicenter of the hammerhead shark universe.
03:37 It's the best dive location in the world.
03:40 As the Eiffel Tower is the symbol of the City of Love,
03:42 this arch is the symbol of the City of Sharks.
03:45 Made famous by Charles Darwin's voyage aboard the HMS Beagle,
03:50 the arch has been renamed in his honor.
03:53 This hot volcanic spot is absolutely unique.
03:59 As soon as you jump in the water, you are immediately surrounded by sharks.
04:02 It's one of the few places on our planet where you can still find yourself in the company of hundreds of sharks.
04:07 A week from the full Moon and in the presence of hundreds of pregnant females,
04:13 the team does not have a minute to lose.
