An aulorhynchid is a member of the Aulorhynchidae, a species of fish related to the stickleback.
The scientific or taxonomic name would be Gasterosteus spp.
A stickleback fish can have a varying number of offspring, typically ranging from 5 to over 100 eggs per breeding season, depending on the species and environmental conditions. Female sticklebacks lay their eggs in nests built by males, who then fertilize them. The number of eggs can be influenced by factors such as the female's size, health, and age.
