Remember the Farquhar bird fly video from a couple of years back?
Well, now courtesy of the filmmakers of Blue Planet II there is video proof that GTs take birds from the air.
Sixteen years after the original The Blue Planet aired, the series returns this month with scientific discoveries and filming firsts that reveal the surprising intelligence and complex social lives of creatures beneath the waves.
Among the most astonishing discoveries was one made in the Seychelles, where filmmakers found that a predatory fish, the giant trevally, leaps into the air to grab sooty terns on the wing.
“A fish that launches itself, missile-like, to take birds from the air, sounded too extraordinary to be true,” said Miles Barton, producer for the Coasts episode. “Despite it being a fishermen’s tale, there was no photographic evidence to back it up. So I was skeptical, to say the least. We arrived and got very excited because, yes, there were splashes everywhere, the fish were leaping out of the water and they did seem to be grabbing birds. They’re amazing shots. A genuine bird-eating fish.”
The footage proved for the first time that the fish can spot moving birds in the air from underwater and calculate the light shift so they can catch their moving target.

Blue Planet II is due for broadcast starting October 29th.
Set your DVR, episode 6 Coasts, is the one featuring the bird eating Trevally.
Angling is the activity of attempting to capture fish. Fish are typically captured in the wild. Methods for capturing fish consist of hand gathering, spearing, netting, angling as well as trapping. Angling could consist of capturing aquatic animals besides fish, such as molluscs, cephalopods, shellfishes, as well as echinoderms. The term is not typically related to capturing farmed fish, or to aquatic mammals, such as whales where the term whaling is more appropriate.
According to the United Nations FAO statistics, the overall number of commercial fishermen as well as fish farmers is approximated to be 38 million. Fisheries as well as aquaculture offer straight as well as indirect work to over 500 million individuals in developing countries. In 2005, the around the world per capita intake of fish captured from wild fisheries was 14.4 kilograms, with an added 7.4 kilograms gathered from fish ranches. In addition to providing food, contemporary fishing is likewise an entertainment leisure activity.
Angling is an ancient method that dates back to at the very least the beginning of the Upper Paleolithic period concerning 40,000 years back. Isotopic analysis of the skeletal remains of Tianyuan male, a 40,000-year-old contemporary human from eastern Asia, has actually revealed that he frequently took in freshwater fish. Archaeology attributes such as covering middens, thrown out fish bones, as well as cave paintings show that sea foods was essential for survival as well as consumed in substantial amounts.
Throughout this period, the majority of people lived a hunter-gatherer way of living as well as were, of requirement, constantly on the action. However, where there are early instances of irreversible settlements (though not necessarily permanently inhabited) such as those at Lepenski Vir, they are generally associated with fishing as a major resource of food.
The British dogger was an early form of sailing trawler from the 17th century, but the current fishing trawler was developed in the 19th century, at the English fishing port of Brixham. By the first 19th century, the fishermen at Brixham needed seriously to expand their fishing area further than previously due to the ongoing depletion of stocks which was occurring in the overfished waters of South Devon. The Brixham trawler that evolved there is of a sleek build and had a tall gaff rig, which gave the vessel sufficient speed to produce long distance trips out to the fishing grounds in the ocean. These were also sufficiently robust to be able to tow huge trawls in deep sea. The great trawling fleet that accumulated at Brixham, received the village the title of'Mother of Deep-sea Fisheries.
This extremely design made huge scale trawling in the sea feasible for the very first time, resulting in a massive movement of fishermen from the harbour in the South of England, to villages further north, such as for instance Scarborough, Hull, Grimsby, Harwich and Yarmouth, which were points of usage of the huge fishing spot in the Atlantic Ocean.
The tiny village of Grimsby grew to become the greatest fishing port on the planet by the mid 19th century. An Act of Parliament was first obtained in 1796, which authorised the construction of new quays and dredging of the Haven to produce it deeper. It was only in the 1846, with the tremendous expansion in the fishing industry, that the Grimsby Dock Company was formed. The building blocks stone for the Royal Dock was laid by Albert the Prince consort in 1849. The dock covered 25 acres (10 ha) and was formally opened by Queen Victoria in 1854 as the very first modern fishing port.
The amazing Brixham trawler wide spread across the world, influencing fishing fleets anywhere. By the conclusion of the 19th century, there were over 3,000 fishing trawlers in commission in Britain, with merely 1,000 at Grimsby. These trawlers were sold to fishermen all over Europe, including from the Netherlands and Scandinavia. Twelve trawlers continued to create the nucleus of the German fishing fleet.
The initial steam powered fishing boats first appeared in the 1870s and used the trawl system of fishing along with lines and drift nets. We were holding large boats, usually 80–90 feet (24–27 m) in length with a beam of around 20 feet (6.1 m). They weighed 40-50 tons and travelled at 9–11 knots (17–20 km/h; 10–13 mph). The initial purpose built fishing vessels were designed and made by David Allan in Leith, Scotland in March 1875, when he converted a drifter to steam power. In 1877, he built the very first screw propelled steam trawler in the world.
Steam trawlers were introduced at Grimsby and Hull in the 1880s. In 1890 it was estimated that there were 20,000 men on the North Sea. The steam drifter was not found in the herring fishery until 1897. The past sailing fishing trawler was built in 1925 in Grimsby. Trawler designs adapted as the direction they were powered changed from sail to coal-fired steam by World War I to diesel and turbines by the conclusion of World War II.
In 1931, the very first powered drum was created by Laurie Jarelainen. The drum was a round device which was set sideways of the boat and would draw in the nets. Since World War II, radio navigation aids and fish finders have already been widely used. The initial trawlers fished over the medial side, as opposed to within the stern. The initial purpose built stern trawler was Fairtry built in 1953 at Aberdeen, Scotland. The ship was much bigger than any other trawlers then functioning and inaugurated the era of the'super trawler '. While the ship pulled its nets within the stern, it could lift out a much greater haul of up to 60 tons. The ship served as a cause for the expansion of'super trawlers'around the world in the following decades.
