Scientists Criticise Social Influencers For Stressing Sharks

Scientists have criticised social influencers for upsetting sharks by filming themselves swimming with them.

As BBC News reports, at least three influencers have been bitten by sharks in less than a year. "I'm seeing these videos every single week now, and it's way more than it ever used to be," it quotes shark scientist Kristian Parton as commenting.

Parton, who also hosts the 'Shark Bytes' YouTube channel, has warned that “we’re going to see people ending up in really serious incidents with sharks."

In July, a fishing influencer almost lost his leg after being attacked by a reef shark while out spearfishing.  In December, a Chinese content creator was bitten in the Maldives. 

Both incidents were caught on camera, as was a bite sustained by Tayane Dalazen, a 37-year old Brazilian lawyer and social media personality, who was on a shark-diving trip off the coast of Brazil last April.

Dalazen was held underwater for several seconds when a nurse shark, more than seven feet (two metres) long, clamped its jaws around her thigh and then released her. Dalazen posted footage of the shark bite online, and it has since been viewed tens of millions of times.

She says she "wasn't there for social media" and didn't touch or provoke the shark, but admits she was too close.

In February last year, a tourist in the Caribbean had both hands bitten off while trying to get a photograph of a bull shark from the shallows, according to local authorities, while a snorkeller in Israel carrying a “selfie stick” in April of last year was killed by sharks.

Scientific studies have shown that approaching or touching a shark induces high levels of hormones called glucocorticoids, which can weaken their immune system and cause increased mortality and aborted offspring, the BBC reports.

Marine Wildlife Around Ireland One of the greatest memories of any day spent boating around the Irish coast is an encounter with marine wildlife.  It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. As boaters fortunate enough to have experienced it will testify even spotting a distant dorsal fin can be the highlight of any day afloat.  Was that a porpoise? Was it a whale? No matter how brief the glimpse it's a privilege to share the seas with Irish marine wildlife.

Thanks to the location of our beautiful little island, perched in the North Atlantic Ocean there appears to be no shortage of marine life to observe.

From whales to dolphins, seals, sharks and other ocean animals this page documents the most interesting accounts of marine wildlife around our shores. We're keen to receive your observations, your photos, links and youtube clips.

Boaters have a unique perspective and all those who go afloat, from inshore kayaking to offshore yacht racing that what they encounter can be of real value to specialist organisations such as the Irish Whale and Dolphin Group (IWDG) who compile a list of sightings and strandings. The IWDG knowledge base has increased over the past 21 years thanks in part at least to the observations of sailors, anglers, kayakers and boaters.

Thanks to the IWDG work we now know we share the seas with dozens of species who also call Ireland home. Here's the current list: Atlantic white-sided dolphin, beluga whale, blue whale, bottlenose dolphin, common dolphin, Cuvier's beaked whale, false killer whale, fin whale, Gervais' beaked whale, harbour porpoise, humpback whale, killer whale, minke whale, northern bottlenose whale, northern right whale, pilot whale, pygmy sperm whale, Risso's dolphin, sei whale, Sowerby's beaked whale, sperm whale, striped dolphin, True's beaked whale and white-beaked dolphin.

But as impressive as the species list is the IWDG believe there are still gaps in our knowledge. Next time you are out on the ocean waves keep a sharp look out!
