Fennecs have large ears, in part, to help dissipate heat. No doubt, they benefit by hearing well also. Warm-blooded animals in hot climates often have larger extremities and appendages than their counterparts in cooler climates. This is a principle called "Allen's Rule," named for Joel Asaph Allen, who first formulated the principle in 1877. See http://en.wikipedia.org/wiki/Allen%27s_Rule for more information about Allen's Rule.
