Let’s get smaller
The team witnessed 67 pairs of wild clowns. The fourth world bleaching event. They measured the physical size of the fish once a month and measured the temperature around the individual anomones every four to six days. Then the team analyzed the data submitted.

Results: During these months, at least 101 of 134 clone fish shrunk in response to heat pressure, and by doing so, the possibility of survival was increased by 78 % which did not decrease compared to 33 fish. And among the pairs of the enrichment, there was a specific proportion of growth between the dominant and subordinate fish. The couples that had entered each other were more likely to avoid heat waves.
“We were very surprised to see these fish shrinking, to make sure, we repeated each fish repeatedly in a five -month period,” Versteg said. “Finally, we discovered that it is very common in this population. It is surprising to see how fast the clonfish can be adapted to a changing environment, and we saw how they organized their size in a flexible way, such as helping people and breeding as a combination of heat.”
Verusiat Et El. No possible mechanism for shrinking has yet been identified, but thyroid hormones can be proposed to mobilize neurvendocrine routes, as they manage hormone growth. Inclusive strategy can also be a means of changing metabolic needs. But there are commercial relationships: when shrinking in response to heat waves ensures maximum survival, birth rates may decrease similarly.
“Our results suggest that individual fish can shrink in response to heat pressure, which has more effect on social conflict, and this shrinking can improve their chances of survival,” Senior author Theresa Roger saidAlso of New Castle University. “If individual shrinking in different species of fish was widespread, it can provide an alternative alternative assumption as to why the size of many fish species is decreasing, and more studies are needed in the area.”
