Species often confused with {name}
Northern Sand Lance
Ammodytes dubius
Key differences: A. dubius generally has a slightly deeper body, a shorter dorsal fin (50-59 rays vs. 54-60 in A. personatus), and a more northern distribution, often overlapping. Differentiation can be challenging and may require meristic counts (fin rays, vertebrae).
Smooth Sand Lance
Ammodytes hexapterus
Key differences: Historically, A. personatus was often considered a subspecies or synonym of A. hexapterus. Recent genetic and morphological studies have largely separated them, with A. personatus being the primary species in the western North Pacific and A. hexapterus in the eastern North Pacific and Arctic. Morphological differences are subtle, often involving vertebral counts and fin ray counts.
American Sand Lance
Ammodytes americanus
Key differences: Found in the Atlantic Ocean. While morphologically similar, its geographic range is entirely distinct, making confusion unlikely in the Pacific.
