NOC, a nine-year-old whale made human-like-sounds.

Vocal bursts averaged about three per second, with pauses reminiscent of human speech. Analysis of the recordings showed that the frequencies within them were spread out into “harmonics” in a way very unlike whales’ normal vocalizations and more like those of humans.

The mimicry is no easy task for whales. NOC had to modify his vocal mechanics to make human-like- sounds. We did not know whales could do that.
We know so much about animals! And we do not know so much about animals!
