Peer pressure can make this clownfish change its stripes

Summary

Tomato clownfish lose stripes based on social cues, according to a new study. The presence of adult clownfish accelerates stripe loss in juveniles. This color change helps young fish integrate into the social hierarchy.

Key Takeaways

1. Tomato clownfish lose their stripes as they mature, with the timing of this loss influenced by their social environment.
2. The presence of adult clownfish accelerates the fading of stripes in juvenile tomato clownfish, indicating a social adaptation.
3. The color change in tomato clownfish is linked to changes in gene expression and may be triggered by hormones produced by the fish's thyroid.
