Clarifying the Size–Frequency Relationship in Clownfish Acoustic Signals

EPEric Parmentier

Key Points

This research aims to clarify how body size influences acoustic variation in clownfish and its relation to social structure.
Analyzed acoustic signals from various size classes of clownfish.
Examined size-based social hierarchies within groups.
Assessed the impact of analytical choices on size-frequency relationships.
Identified a clear size-frequency relationship in clownfish acoustic signals.
Demonstrated that prior analyses masked natural size variation.
Highlighted the importance of accounting for morphology in understanding acoustic differences.

Abstract

ABSTRACT Body size is the principal determinant of acoustic variation in anemonefish, reflecting both the mechanics of sound production and the size‐based structure of their social hierarchies. In Amphiprion percula, the absence of a reported size‐frequency relationship has led to the interpretation that small acoustic differences are rank‐specific. We show that this outcome stems from analytical choices that obscure natural size variation, including pooling individuals across groups and removing size–rank covariance. Because behavioural categories correspond to distinct size classes, morphology must be explicitly accounted for.
