Mediterranean Sand Smelt
Atherina hepsetus
Key differences: A. hepsetus typically has a slightly more pointed snout and a shorter anal fin (1 spine, 12-15 soft rays) compared to A. presbyter (1 spine, 15-19 soft rays). The silvery stripe in A. hepsetus may also be less pronounced or narrower.
Big-scale Sand Smelt
Atherina boyeri
Key differences: A. boyeri generally has larger scales (fewer scales along the lateral line, typically 40-48 vs. 55-65 in A. presbyter) and a more robust body. Its geographic range overlaps, but A. boyeri is often found in more enclosed, hypersaline lagoons.
Lesser Sand Smelt
Atherina mochon
Key differences: A. mochon is very similar and often confused with A. boyeri. Distinguishing features are subtle, often requiring meristic counts (e.g., vertebral count, fin ray counts) and can be challenging without expert knowledge. Some consider A. mochon a synonym or subspecies of A. boyeri.
