Blennioid fishes comprise almost 900 described species, most of which are associated with coastal environments. Yet, essentially nothing has been published regarding the reproductive biology of more than 90 percent of blennioid species. This chapter explores spawning, mate choice, and parental care in blennioid species within an evolutionary context. The ecological importance of this taxon cannot be overstated. Blennioids, along with gobioids, constitute the dominant component of cryptic reef and coastal fishes, and as such play a key role in coastal and reef community ecology, trophic cycling, and within-habitat energy flow. The chapter provides an informative review of their reproductive biology and discusses their oviposition sites, mating systems, fertilization mode, alternative reproductive tactics, size dimorphism and patterns of male reproductive success, and external fertilization of demersal eggs.
