Dominant juvenile clownfish (Amphiprion percula) emerging from size-matched pairs grew twice as much as subordinates, with distinct feeding, agonistic, and gene-expression profiles.
- Why it matters: Dominance hierarchies are dynamic, but it remains unclear how individuals coordinate phenotype changes with social context during role adoption.
- What they did: In 30 replicates, size- and age-matched rival pairs were housed together and solitary controls separately; growth, weekly feeding and agonistic behaviors, and end-point whole-body transcriptomes were measured.
- The result: Dominant fish showed coordinated upregulation of conserved vertebrate growth and ossification-related genes and downregulation of satiety-associated genes, while subordinate and solitary fish had comparable growth.
