Highlight Hatchetfish
Sternoptyx pseudodiaphana
Key differences: S. pseudodiaphana is very similar to S. diaphana but can be distinguished by subtle differences in the number and arrangement of photophores, particularly the pre-anal and post-anal series. Morphometric ratios, such as eye diameter to head length, can also differ slightly.
Spiny Hatchetfish
Argyropelecus hemigymnus
Key differences: While also a marine hatchetfish, Argyropelecus species generally have a more pronounced dorsal blade or spine, and their body shape, while compressed, is often less extreme than Sternoptyx. The arrangement and number of photophores also differ significantly.
Silvery Hatchetfish
Sternoptyx obscura
Key differences: S. obscura is another closely related species. Differentiation often requires careful examination of photophore counts and patterns, particularly the number of photophores in the pre-anal and post-anal series, and subtle differences in body proportions.
