Evenly spaced line of semicircular scales along the centre of the upper surface behind the head. The anus is also situated just in front of the tip of the anal fin, whereas inÂ AtherinasomaÂ microstomaÂ it is situated just behind. Schools of tens of thousands close to the waterâ€™s edge, where they feed on both bottom-living and planktonic prey. The schools are sometimes mixed with another abundant species, the small-mouthed hardyhead A.microstoma, although that species tends to live in the less saline reaches of estuaries.
