They process sonar information in a visual way, and communicate it long distance. When have you last yelled at someone to place the 3D image of a swarm of krill in their minds?

You don't really need 3d point cloud precision for this. Here, I can do it right now. KRILL ON MY LEFT BRO!
Given the bandwidth of 20 hz whale sounds, its preposterous to imagine them containing a more sophisticated depiction of things than that.
Okay but that completely misses the point of what they were communicating.
If you're skeptical about the communication that's one thing, but the thing you're offering is a substitute is not remotely equivalent.
My understanding is that whales can interpret echoes of their own signals and read them as a map of physical features around them, and can exchange these signals with each other.
Linguistic abstraction is a different type of thing altogether, and I don't know what point would served by going up to whales and telling them that they "don't need" the form of communication they actually use.
The comment I was replying to said
>When have you last yelled at someone to place the 3D image of a swarm of krill in their minds?
To which I say this is preposterous because the amount of data that could possibly fit inside of whale calls is orders of magnitude smaller than the data it would take to make a 3d image of a swarm of krill. Whatever it is they are saying, it must be a significantly compressed reduction, perhaps similar to the "map" that is communicated when you ask a stranger on the corner how to get somewhere. Why should one whale take the time transmit a literal 3d terrain map for another whale when mere driving instructions would suffice?
Yes, it's 3D point cloud precision.
(Source: I study echolocation in bats, and many of the classic texts cover echolocation in cetaceans as well.)
Therefore the comment I was replying to was obviously and absurdly generous in its interpretation of whale brain capabilities. Even believing they do point cloud echolocation is a bit generous considering what whales actually need to accomplish. A low resolution 3d blob cloud (in contrast to point cloud) would be all the comprehension of the world they might ever need.
Unlike bats, whales don't have to track down and catch the krill after reaching them.
Really? How do we know? What does in a visual way even mean when it’s not eyes?

Took me a bit to find this, google, brave search and bing are worthless. Had to use a work-around to find the exact title, and search for that.
