'Shrinking Nemo': Smaller clownfish sound alarm on ocean heat

Clownfish, similar to those in the movie Finding Nemo, are shrinking in response to marine heatwaves, a recent study reveals. Conducted in Kimbe Bay, Papua New Guinea, researchers found that clownfish slimmed down significantly when ocean temperatures spiked in 2023. This discovery sheds light on how various fish species are adapting to climate change, with 75% of the studied clownfish shrinking during the heatwave. The findings suggest a potential shift in fish size due to environmental stress, which may have significant implications for marine biodiversity.
