An inspiring story that shows how the presence of a marine species can affect the entire economy and the whole society of one of the smallest islands of the Azores, the Island of Santa Maria. It is the only place in Europe where a large number of whale sharks are sighted and in addition their migration is shrouded in mystery, no one knows where they come from, where they are going … and why they appear surrounded by thousands of tunas. It also accompanies the scientific expeditions that for 11 years have tried to unveil the secrets of these giants and to know if their recent presence is linked to global warming and rising water temperatures around the Azores.

00:00All right, Cristina. Thanks.
00:15For me, the Aesos is really one of those few remaining special places on our planet.
00:21We're in the middle of the Atlantic Ocean, and suddenly the ocean floor rises from thousands of meters
00:27to create a marine sanctuary in the middle of the Atlantic.
00:38This is a place where great ocean wanderers merged to on their migrations across the Atlantic.
00:50You never know what you're going to find in these waters.
00:53It's just such a wild and unpredictable place.
01:02This is one of the most amazing marine life stories in the Atlantic Ocean.
01:06And it was completely unknown to everyone, even to science.
01:12Everyone except fishermen. They all knew about them.
01:15They just didn't know what they were.
01:22Pintado means spotted.
01:25They couldn't really explain to me what they were, but they said that each time they would see this massive
01:31animal,
01:31may be more than 10 meters long, they would be able to fish an abundance of tuna.
02:04These whale sharks are also massive.
02:06It's sometimes 10, 12 meters long.
02:19This is one spectacular event that happens about once every 10 years.
02:27It's still a mystery for us, why they come this far north.
02:30We're talking about the biggest fish in the world.
02:34It was like that in 2008.
02:36It apparently is the same now in 2019.
02:40This year we were better prepared.
02:42We came with an arsenal of scientific tools.
02:45These cameras were developed to investigate the mysteries of the animals of the open ocean.
02:52Where are these massive whale sharks coming from?
02:55Where are they going when they leave?
02:57Why are they traveling with this enormous amount of tuna?
03:02Why are they traveling with this whale sharks?
03:04That way.
03:05Okay, pass.
03:06Canal off.
03:07Canal off.
03:08Oh, the way of the crè.
03:10The way of the crè.
03:10The way of the crè.
03:12Look at the cat.
03:14Look at the cat.
03:15Look at the cat.
03:16Okay, okay.
03:17Silvino.
03:18Okay.
03:19Santa Maria became known as the only place in Europe where we have whale sharks.
03:23I don't know of any other place in the world where we find these aggregations of large whale sharks,
03:29these massive schools of tuna, and there is no plankton for them to feed.
03:33So we believe that they might be feeding on the bait fish that the tunas trade.
03:41The south shore of Santa Maria really seems to be prime whale shark habitat.
03:47We hope to learn more about the reasons why the whale sharks associate with tuna
03:52and why is this connection so important to them.
04:03So now, Joaquin Oldeburg.
