Abstract

The grass goby Zosterisessor ophiocephalus sperm-duct gland extract displayed antimicrobial activity against gram-positive and gram-negative bacteria. This suggests that sperm-duct gland mucins might be functional in protecting eggs and possibly parents from pathogens, an activity of great adaptive value for Z. ophiocephalus, which lays eggs in mud nests.
