There have been two interesting studies that further support the hypothesis of somewhat complex communication system. One was done in Florida with wild dolphins who hunt cooperatively. One dolphin drives the fish,while others act as a barri

Actually no, orcas echolocate a lot and also exchange quite a few calls while hunting fish (based on acoustic tag data).

We do, actually, for dolphins at least. Researchers did an experiment where dolphins had to coordinate their actions (push 2 buttons together) without seeing each other. So they coordinated their actions acoustically by communicating when t

Motivation could be an issue. What if they do not want to communicate with us? What if we are too slow for them? Dolphins produce burst pulses that have interclick interval of just few milliseconds. We cannot even hear these individual clic

No, it is not that simple. Humpback whales have been observed to interfere and mess up with orcas protecting gray whale calves from being killed. It was observed several times and researchers think that humpbacks just really cannot stand or

The obstacle is that we still do not fully understand nor are able to replicate their sonar, even the Navy that has been studying dolphins for decades still cannot duplicate biosonar (read more here: https://www.nationalgeograph

It is not easy, we have not yet cracked the code, plus will they even have the motivation or any interest to communicate with us? What we do know is that they produce a variety of signals, some very complex and their communication is super

We are trying to do something similar (citizen science + AI) but for the acoustic data,our first model can identify manatee calls and mastication (chewing) sounds. https://manatee-chat-demo.appspot.com/

Humpback whales have mirror neurons (the ones implicated in "theory of mind") so they might show "compassion". There is so much we still do not know about marine mammals...

Humpback whales appear to show empathy towards other species. We have 115 documented cases of them doing so (and it is a lot given how hard it is to observe them). http://oceanwildthings.com/2018/06/what-humpback-w

Oh, yes, Dr. Lilly and his NASA funded study. All acid, sex and other things aside, some of the stuff he did was indeed interesting, if only to get to know dolphins in a way impossible in the wild. There was one NPR interview with Margaret

Speaking of dolphins (and whales for that matter), there is a reason why it has been so hard to not just "communicate" with them but to even understand the function and the meaning of a number of calls they make.It appears that it

Yet, after nearly 5 decades of research we are still unable to crack their code. We do know however that some sequences they make do not seem to be random.Our problem is to penetrate the communication system that is not visually based,and i

Even with a tag attached to a whale it is still impossible to be completely sure who made a sound. This is a big issue that has been haunting marine mammal communication research for decades. Hard to establish the function of the call when

Here is a question, how do they determine who is whistling to them if they do not see them? Is whistler's identity encoded in a whistle somehow? And if yes, then how? In cetacean whistles it is believed that dolphin's identity is

Denise Herzing used synthetic whistles trying to label things in our human way, pretty much the extension of Herman's line of thought. But we do not know if dolphins indeed label things in their natural communication system. Signature

The role of larynx in cetacean sound production is still debated, but we do know that they posses at least 2 sound generating mechanisms that could work independently and simultaneously. It appears that right side phonic lip is involved in
