‘Shrinking Nemos’: smaller clownfish sound alarm on ocean heat

Submission Statement:

Clownfish like the ones we saw in Finding Nemo are actually shrinking to deal with hotter oceans, which scientists found during a 2023 heatwave.

* Clownfish in Papua New Guinea shrank during 2023 marine heatwaves.
* 75% of them became shorter, not just lighter.
* Scientists say this could be a survival method to use less energy.
* Study shows animals are physically changing to cope with climate stress.
* Similar body changes seen in birds, lizards, and marine iguanas.

This could really affect how marine ecosystems work in the future.
