From: Individuality embedded in the isolation calls of captive beluga whales (Delphinapterus leucas)
IPI contours of PS1 calls from five belugas (n = 16). Individual identities are represented at the upper left. Sixteen samples each from T, G, N, and M were randomly selected to match the number of depicted IPI contours of H from which the smallest samples were collected
