propagandaTo survive warm survival, Clown fish It reduces its size. Scientists note that some of these orange lines Throw a heat wave In front of the coast of the New Guinea. The fish they lost were more likely to survive.
Las Heat waves It is frequent and increasingly underwater Because climate change. The water temperature can be increased Numan marine navigators It is a home for clown fish, forcing them to adapt to survival.

Watch the scholars and They measured 134 clown fish In Kimby Bay during an intense heat wave in 2023 it continues to whiten coral reefs around the world. Discover that 101 clown fish reduced their length on one or more occasions Due to heat stress.
“At first we were really surprised when we saw they were Reducing“The results were published on Wednesday in” Science Advances “.
Although scientists still do not know how clown fish shrink, the idea is that they can be Re -absorbing the issue of their bones. Low size can help clown fish Power During a stressful heat wave, since smaller fish need less food.

“This is another strategy that fish will use Facing a changing world“Simon Thorold, an expert in peripheral environment at the Woods Hall Foundation for Oceanic Sciences that did not participate in the new study. This tactic helps smuggled fish on Deal with heat waves The short term, but it is not yet clear how they will go if they had to do so Keep it in the coming yearsAfirma Torrold.
Researchers discovered this The contraction was temporary. According to Melissa Versege, the author of the study and researcher at Newcastle University, The Clown Fish They had the ability to recover And grow again when their surroundings became less tired, indicating that living organisms are preserved Flexible for warmth from the planet. “These natural systems are truly stress, but they have an incredible recovery capacity,” says Versteeg.
