Researchers and scientists of the University of Princeton and Missouri in Saint Louis have observed movements, routes, sudden turns of ameba specimens and of a particular type of zooplancton "hunting" for food. From the observations it has been concluded that unicellular organisms too are able to adopt startegies based on memory to feed themselves: amebas and plancton did not move at random in their environment, but they used sophisticated research strategies, moving in order to optimise the search for food.
