The northern lampfish, also known as smallfin lanternfish, is a small oceanic fish in the family Myctophidae. First described by husband and wife ichthyologists Carl H. and Rosa Smith Eigenmann in 1890, it is named for the numerous small round photophores that line the ventral surface of its head and body.W CalCOFI holds 12,981 observations of it in 2 datasets between 1951 and 2023, as larva.R

One row per dataset, and beside it one cell per year, darker with more observations — the same strip the front door draws per dataset. Each row ends with the name that dataset uses (dataset_taxon); the accepted name is written once, in the title above. A quiet pill marks a name the authority does not accept.
