Scientists documented[记录] what is known as parental[双亲的] courtship[求爱] behavior in the lab. That’s when an animal shows off its parenting skills to attract a mate.

University of Florida Researchers studied the sand goby[沙鰕虎鱼], a small fish native to the European coast that is among the twenty percent of fish species that exhibit parenting behavior.

Sand gobies nest[筑巢] under sea shells, and the males not only defend the nests, but also hollow[空] them out. Then, once the eggs are laid, they use their pectoral[胸鳍] fins to fan them, creating a current of oxygenated[氧气的] water that helps the eggs mature[成熟].
