At 107 grams, the spider monkey brain is twice the size of a howler monkey's of equivalent body size; this is thought to be. a result of the spider monkeys' complex social system as well as their diet, which consists primarily of ripe fruit from a. wide variety (over 150 species) of plants.orming loose groups of 15-25 individuals, spider monkeys are highly agile; they are said to be second only to the gibbons in this respect. During the day, spider monkey groups break up into smaller subgroups of 2-8 individuals; this social structure ('fission-fusion') is found in only one other primate, the chimpanzee.
