A surfer dies after a shark attack in eastern Australia

A man died this Tuesday from injuries caused as a result of the bite on the thigh of a shark while surfing on Tuncurry Beach, more than 310 kilometers north of Sydney, the first recorded death from a shark attack in 2021 in Australia.The victim was attended by emergency services after being rescued from the water, although they failed to save his life, the New South Wales State Police reported in a statement.As a result of the incident, the Australian authorities closed the Tuncurry beach and a nearby beach, in the town of Forster, and started a operational to search for and identify the shark who attacked the surfer.The record of shark attacks in Australia recorded by the Taronga Zoo indicates...

Sharks use Earth’s magnetic field as GPS to swim long distances

Sharks use the Earth's magnetic field as a kind of natural GPS to swim great distances across the oceans, US scientists suggest in a study published in the specialty magazine Current Biology. Researchers at Florida State University conducted laboratory experiments with a small species of hammerhead shark (Sphyrna tiburo) and found that the behavior is similar to that observed in other marine animals, such as turtles. Sharks are able to cross seas and find their way back to feed and reproduce. We know that sharks can respond to magnetic fields. We didn't know that they detected them and used them as an aid to navigation. There are sharks that can travel 20 thousand kilometers and end up in the same place ", said one of the study's au...

This fascinating website allows you to track sharks around the world (spoiler: in Spain we have two)

OCEARCH is a global non-profit organization conducting unprecedented research on sharks in our ocean to accelerate the return of waters to balance and abundance. Sharks are the guardians of the ocean's balance and the path to abundant and healthy oceans passes through them. It is critical that we understand the full life history of these top predators so that responsible management policies can be enacted to protect them. That is why OCEARCH has been capturing these creatures for years, collecting tissue and blood samples, weighing and checking their health before implanting geolocation tags., in this video you can see the process of tagging a shark: Sub-adult female white shar...

Sharks use magnetic fields to orient themselves in the ocean

The Sharks, like turtles and other marine animals, use magnetic fields to orient themselves on their long ocean voyages, according to a study published in the journal Current Biology.It was something that the scientific community had long sensed but had not been able to prove until now, thanks to the study led by biologist Bryan Keller, a researcher at the Coastal and Marine Laboratory of Florida State University. !function(f,b,e,v,n,t,s) {if(f.fbq)return;n=f.fbq=function(){n.callMethod? n.callMethod.apply(n,arguments):n.queue.push(arguments)}; if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0'; n.queue=[];t=b.createElement(e);t.async=!0; t.src=v;s=b.getElementsByTagName(e)[0]; s.parentNode.insertBefore(t,s)}(window,document,'script', 'https://connect.facebook.net/en_US/fbevents.js')...

They show that sharks use magnetic fields to orient themselves: "It is the GPS of nature"

Sharks, like turtles and other marine animals, use magnetic fields to orient yourself on your long ocean voyages, in accordance with A study published this Thursday in the magazine Current Biology.It was something that the scientific community sensed for a long time, but that what it had not been demonstrated until now, when it has been done by a study led by biologist Bryan Keller, a researcher at the Coastal and Marine Laboratory at Florida State University.For the study, Keller used shovelhead sharks, a small-sized species native to the American continent. His team captured 20 specimens and He placed them in a coil to simulate magnetic field conditions.In the coil, the sharks they moved in one direction or another based on the location of the simulated magnetic field with respect to it...
