Can goby spermatozoa pass through the filament adhesion apparatus of laid eggs?

SEM observations of the egg adhesion of grass goby Zosterisessor ophiocephalus show perforations between filament insertions on the basal plate. These are adequate in size to let through spermatozoa which eventually reach the micropyle. This accounts for post-attachment egg fertilization occurring n...

Description
Summary:SEM observations of the egg adhesion of grass goby Zosterisessor ophiocephalus show perforations between filament insertions on the basal plate. These are adequate in size to let through spermatozoa which eventually reach the micropyle. This accounts for post-attachment egg fertilization occurring naturally and in artificial fertilization experiments. Copyright 2001 The Fisheries Society of the British Isles
