Observations about the limited survival of dolphins in captivity can be related to the fact, that, in captivity, they build very fast the exact model of the space available. After a while (see "stress") the space is known very well and this could be a cause of stress. A strong brain needs always new information. The solution could be a larger environment, in which, additionally, the configuration should be changed every now and then. Contrary to general belief, animals, including dolphins, should feel better in interaction with man in a controlled environment, in the above conditions, than in liberty.
The shark
The shark has the same environmental problems as the dolphin. It behaviour is so primitive that, based on the theory, it should have only PSM, with extremely few models, given by the interaction with the external reality. Water seems to be a relatively hostile environment for the development of the intelligence.
The whale
The whale can navigate at thousands of kilometers of open see and return to its start point. It is also known that they seem to communicate by sounds similar to a song.
It is believed about whales that they can use the magnetic field of the bottom of the ocean to build a map (image model). If so, they could find their position on this primitive map. However, if this map becomes incorrect, due to changes of the magnetic field, they could navigate in a wrong direction, including landing on ocean shores. Moreover, if taken back to the open see, they will repeat the path that lead them to trouble, because their navigation system indicates the same direction as before. Simply, the whales get lost, and have no means to find again their position in the ocean.
We can take a risk and say that, if the information of navigation associated with the magnetic field were recorded in a story-type model (equivalent to a map), then the whale would know how to return to the starting point by "rewinding the tape". Thus, it has to compare the story-type model with IR generated by the direct interaction with external reality.
If this is the method, a transfer of this itinerary model from a whale could be possible to another, which did not make this trip yet, through that "song". Seems fascinating, but also it is possible to check by experiment.
ETA 25: Very complicated operations on image models (walk, jumps, climbing trees) of humans
We will apply the theory to see the exact way of walking, jumping and tree climbing at humans. In accordance to MDT, an action on the external reality (e.g. walking) implies the existence of a long-range action model (ZAM). This model generates the approximate plan of the action. ZAM will build and activate a number of local models (ZAM and AZM) to reach its goals.
