Fig. 5. Relative frequency of sounds produced during aggressive social interactions
in the multiband butterflyfish, Chaetodon multicinctus. The tail
slap, grunt and dorsal-anal fin (DA) erect acoustic behaviors were produced
exclusively by territory residents and directed towards bottled conspecifics.
Grunt trains were recorded only from bottled fish (most frequently when in
pairs) when territory holders came into view and may be an alert or distress
signal to the mate. The fin flick acoustic pulse was produced by both resident
and bottled fish during confrontations. N values are given beneath
each behavior.
