Shock shark sighting in Antarctica’s near-freezing deep

[ad_1] MELBOURNE, Australia (AP) — An ungainly barrel of a shark cruising languidly over a barren seabed far too deep for the solar’s rays to light up was an surprising sight.

Many specialists had thought sharks didn’t exist within the frigid waters of Antarctica earlier than this sleeper shark lumbered warily and briefly into the highlight of a video digicam, researcher Alan Jamieson stated this week. The shark, filmed in January 2025, was a considerable specimen with an estimated size of between 3 and 4 meters (10 and 13 ft).

“We went down there not anticipating to see sharks as a result of there’s a basic rule of thumb that you simply don’t get sharks in Antarctica,” Jamieson stated.

“And it’s not even somewhat one both. It’s a hunk of a shark. This stuff are tanks,” he added.

The digicam operated by the Minderoo-UWA Deep-Sea Analysis Centre, which investigates life within the deepest components of the world’s oceans, was positioned off the South Shetland Islands close to the Antarctic Peninsula . That's effectively contained in the boundaries of the Antarctic Ocean, also called the Southern Ocean, which is outlined as beneath the 60-degree south latitude line.

The middle on Wednesday gave The Related Press permission to publish the photographs.

The shark was 490 meters (1,608 ft) deep the place the water temperature was a near-freezing 1.27 levels Celsius (34.29 levels Fahrenheit).

A skate seems in body immobile on the seabed and seemingly unperturbed by the passing shark. The skate, a shark relative that appears like a stingray, was no shock since scientists already knew their vary prolonged that far south.

Jamieson, who's the founding director of the College of Western Australia-based analysis middle, stated he may discover no report of one other shark discovered within the Antarctic Ocean.

Peter Kyne, a Charles Darwin College conservation biologist impartial of the analysis middle, agreed {that a} shark had by no means earlier than been recorded to date south.

Local weather change and warming oceans may doubtlessly be driving sharks to the Southern Hemisphere’s colder waters, however there was restricted information on vary modifications close to Antarctica due to the area’s remoteness, Kyne stated.

The slow-moving sleeper sharks may have lengthy been in Antarctica with out anybody noticing, he stated.

“That is nice. The shark was in the proper place, the digicam was in the proper place and so they acquired this nice footage,” Kyne stated. “It’s fairly important.”

The sleeper shark inhabitants within the Antarctic Ocean was possible sparse and tough for people to detect, Jamieson stated.

The photographed shark was sustaining a depth of round 500 meters (1,640 ft) alongside a seabed that sloped into a lot deeper water. The shark maintained that depth as a result of that was the warmest layer of a number of water layers stacked upon one another to the floor, Jamieson stated.

The Antarctic Ocean is closely layered, or stratified, to a depth of round 1,000 meters (3,280 ft) due to conflicting properties together with colder, denser water from beneath not readily mixing with contemporary water operating off melting ice from above.

Jamieson expects different Antarctic sharks dwell on the identical depth, feeding on the carcasses of whales, large squids and different marine creatures that die and sink to the underside.

There are few analysis cameras positioned at that particular depth in Antarctic waters. These which might be can solely function through the Southern Hemisphere summer time months, from December by means of February.

“The opposite 75% of the 12 months, nobody’s taking a look at all. And so that is why, I believe, we often come throughout these surprises,” Jamieson stated.
