摘要
Information on the feeding habits of a paedomorphic population of Ambystoma ordinarium is presented. Caddisfly larvae composed the greatest portion of the diet in numbers and frequency of occurrence, but grasshoppers were the most abundant item by volume. Smaller paedomorphs selected large numbers of small prey, whereas the largest size class fed on fewer but larger prey.
