Scientists say the discovery was a big surprise and could help explain the rapidly declining size of other fish in the world's oceans.A growing body of evidence suggests animals are shape shifting to cope with climate change, including birds, lizards and insects.

"Nemos can shrink, and they do it to survive these heat stress events," said Dr Theresa Rueger, senior lecturer in Tropical Marine Sciences at Newcastle University.The researchers studied pairs of clownfish living in reefs off Kimbe Bay in Papua New Guinea, a hot spot of marine biodiversityThe wild clownfish are almost identical to the ones depicted in the movie Finding Nemo, in which a timid clownfish living off the Great Barrier Reef goes in search of his son.

The scientific study took place in the summer of 2023, when temperatures shot up in the oceans, leading to large swathes of coral turning white.The scientists took multiple measurements of individual clownfish coping with the heat.

They found the tiny fish didn't just lose weight but got shorter by several millimetres. And it wasn't a one-off - 75% of fish shrunk at least once during the heatwave.

Dr Rueger explained: "It's not just them going on a diet and losing lots of weight, but they're actively changing their size and making themselves into a smaller individual that needs less food and is more efficient with oxygen."Since the start of that invasion in February 2022, Russia has made more than three times as much money by exporting hydrocarbons than Ukraine has received in aid allocated by its allies.

Data analysed by the BBC show that Ukraine's Western allies have paid Russia more for its hydrocarbons than they have given Ukraine in aid.Campaigners say governments in Europe and North America need to do more to stop Russian oil and gas from fuelling the war with Ukraine.

Proceeds made from selling oil and gas are key to keeping Russia's war machine going.Oil and gas account for almost a third of Russia's state revenue and more than 60% of its exports.
