The authors conclude that monkeys can represent the numerosities 1 to 9 at least on an ordinal scale. [109] Ants are able to use quantitative values and transmit this information. [110] [111] For instance, ants of several species are able to estimate quite precisely numbers of encounters with members of other colonies on their feeding territories.
