From: Vocalizations of wild West Indian manatee vary across subspecies and geographic location
Violin plots and boxplots illustrating the values of three different acoustic parameters (center frequency, maximum frequency, and duration), compared across the three geographically distinct manatee populations. The boxplot represents the upper and lower quartile values. The black line represents the median and the red dot represents the mean. Plots for Antillean manatees are in blue and Florida manatees in red.
