FLYING GLIDING SPIDERS ON SHOW IN THIS VIDEO

Gliding spiders can almost fly in this video

Published on Aug 19, 2015

Researchers claim that they have discovered the first spider that can maneuver itself while gliding through the air just like a base jumper. By way of proof they released a video of the arachnid seemingly steering its way down after being dropped from a tree.
Before coming to their conclusion, scientists dropped 59 spiders from as high as 20 to 25 meters (65 to 80 feet) above ground. They chose so-called “flatties” – “camouflaged” flat-shaped spiders from Panama and Peru for the experiment. The scientific name for the species is Selenops banksi (S. banksi).
Almost all of the dropped spiders from a sample size of 55 never made it to the ground, but glided back to the trunk of the tree from which they were dropped, the researchers said in their study published on Wednesday in the Journal of the Royal Society Interface.

The spider in the video released by researchers visibly controls its line of fall.The researchers say the spiders in the air are more agile than cats as they can turn themselves in milliseconds, pointing their heads downwards to glide. The spiders’ legs were moving on their way down, so scientists believe that they may be being used to steer.

The landing does not hurt the creatures because of their low mass.

“We really did not expect to see gliding behavior in spiders,” Stephen Yanoviak, a head of the study and a tropical arthropod ecologist at the University of Louisville in Kentucky, told National Geographic.The scientists believe that for spiders, gliding is a way of avoiding the ground, which is likely to be full of potential predators.

“My guess is that many animals living in the trees are good at aerial gliding, from snakes and lizards to ants and now spiders,” said Robert Dudley, a professor of the University of California, Berkeley said, as cited by the university website.

“If a predator comes along, it frees the animal to jump if it has a time-tested way of gliding to the nearest tree rather than landing in the understory or in a stream,” he added.Professor Yanoviak believes the results of the study will provoke further research.

“This study, like the first report of gliding ants, raises many questions that are wide open for further study,” he said. “For instance, how acute is the vision of these spiders? How do they target a tree? What is the effect of their hairs or spines on aerodynamic performance?” he added.

Professor Yanoviak discovered a decade ago that some species of ants are capable of gliding. Since then he has looked for other wingless arthropods that can jump from one tree to another one.

Giant tiger shark reportedly caught off NSW North Coast Australia

GIANT TIGER SHARK CAUGHT IN AUSTRALIA

Northern NSW surfers support shark cull

Conservationists investigate reports of the capture of a 6-metre tiger shark on the NSW North Coast while local surfers vote for a partial shark cull at a community meeting on Monday.

A fisherman claims a four-metre tiger shark caught off the NSW coast last month ate a six-foot hammerhead shark moments before it was reeled onto his boat.

Pictures of the massive shark emerged on Facebook on Tuesday, with varying stories about how and where it was caught.

Byron Bay-based conservation group Positive Change for Marine Life shared two images of the dead shark on its Facebook page on Tuesday, asking if anyone had more information.

Spokesman Karl Goodsell told Fairfax Media that several sources had told him the shark was caught off Nine Mile Beach, on the Tweed Coast, in the past few days.

However, a spokesman for the Department of Primary Industries said it could not confirm when or where the shark was caught.

“DPI is not investigating this incident, as no illegal activity has occurred,” a spokesman said.

The fisherman, who contacted local paper the Northern Star and gave his name only as Matthew, said he caught the shark about three weeks ago, 22 kilometres off Tweed Heads.

He said he was trying to catch a six-foot hammerhead shark initially when the tiger shark swallowed it whole.

“I was fighting the hammerhead and he came up and swallowed it,” he told the paper. “You can’t turn around and go no, don’t touch, to something like that.”

He had lived in the area since he was 4, he said, and seen much larger sharks than this one – which he sold to the fish markets, keeping the jaws as a souvenir.

“I’ve dived with sharks bigger than that, it’s only a little one,” he said.

“I’ve seen tiger sharks 24-feet-long off Tweed.”

Commercial shark fishing is not illegal in large parts of the ocean off NSW and Queensland.

The frightening photos show the shark lying on what appears to be the deck of a commercial fishing vessel, with several cuts and blood seeping out of its massive jaw.

The DPI spokesman said the shark appeared to have been captured by a long-line and it looked to be about four metres long.

“This size is not unusual for a tiger shark,” he said.

The photo was initially posted by a Facebook user, Geoff Jones, who said he did not know its origins.

Another Facebook user, Nicholas X Morley, claimed he was given the image by “a mate that works in the fishing industry” who said it was caught three or four days ago, off Seven Mile Beach.

He said the fisherman handed its body to the CSIRO but a CSIRO spokesman said it had not been contacted about the shark.

Mr Goodsell said he had been able to positively identify the particular commercial fishing boat in the photos and confirm that it is a registered and licensed commercial shark fishing boat operating off northern NSW.

He said it was a legal catch, which highlighted the problem with commercial shark fishing in Australia.

“Fishermen between northern NSW and Cape York take around 78,000 to 100,000 sharks a year, some within the Great Barrier Reef and some of the species taken include … critically endangered scalloped hammerhead and the protected great white.”

“We don’t see any point in pursuing the fisherman; it’s not their fault for doing their jobs. The problem comes from the government who allow these fisheries to exist for protected and endangered species.”

Several sharks have been menacing surfers and swimmers off the NSW North Coast in recent months, causing the closure of several beaches.

Surfer Tadashi Nakahara was mauled to death in February and 11 others have been attacked, including bodyboarder Matt Lee and surfer Craig Ison, who both remain in hospital with serious injuries.

At a community meeting on Monday night, almost 200 surfers voted for a partial cull of sharks following an unprecedented number of attacks and sightings.
