I’m Melting
As the oceans grow increasingly acidic, they’re claiming yet another casualty: sharks.
New research shows that the acidic water, a byproduct of human-induced climate change, is damaging and destroying the tiny scales on sharks’ skin, according to Newsweek. As a result, the sharks can’t swim or hunt as well — and that could potentially wreak havoc on the already-fragile ecosystems in which they live.
Fast Changes
A team of German and South African scientists found that after just nine weeks of exposure to acidic water, over nine percent of the sharks’ denticles — those are the tiny scales — were damaged, according to research published on Thursday in the journal Scientific Reports.
While the experiment isn’t exceptionally robust — there were only three sharks in the cohort that got the acidic water treatment — the findings are a troubling sign for the future of marine life.
Silver Lining
Thankfully, the study turned up some good news as well. The researchers found that the sharks were able to moderate their bodies’ chemistry to adjust to the increasingly acidic water. Other than the damaged and destroyed scales, they seem to be unharmed.
Luntz Auerswald, an environmental researcher from South Africa’s Stellenbosch University, told Newsweek that the team “expected that they would be able to regulate their acid-base balance in the short term as a response to a lowered pH. We were unsure, but not surprised, that they can keep this regulation up for extended periods.”
“The corrosion of the denticles, however, came as a surprise,” he added. “We did not expect this.”
