Abstract
The "intelligence" of sixty kinds of animals was rated by university students (N=117) using a 100-point scale. Although the results generally corresponded with the so-called "phylogenetic scale" from "amoeba" to "chimpanzee," several interesting points were observed. First, "Japanese monkey" was rated higher than "orangutan" and "gorilla." Second, "dog" and "dolphin" were rated as high as the Primates. Third, mimic birds and social insects were rated higher than other birds and insects, respectively. Finally, a kind of fish ("shark") was rated higher than a mammal ("mole").
