This chapter discusses the lek mating system of marine iguanas. Marine iguanas along the coastlines of the Galápagos Islands exhibit a lek mating system in which males cluster during the mating season and defend small, symbolic territories that lack material resources. This chapter identifies possible criteria females might use to evaluate male quality. It examines the contribution of behavior, body size, condition, ornamentation, and ectoparasite load to relative mating success.
