Editing Opah (section)

== Species ==
Two living species were traditionally recognized, but a [[Taxonomy (biology)|taxonomic]] review in 2018 suggests the idea of splitting ''L. guttatus'' into several species, each with a more restricted geographic range, bringing the total to six. The six species of ''Lampris'' have mostly non-overlapping geographical ranges, and can be recognized based on body shape and coloration pattern.

===Extinct species===
* † ''[[Lampris zatima]]'', also known as ''Diatomœca zatima'', is a very small, [[extinct]] species from the late [[Miocene]] of what is now [[Southern California]] known primarily from fragments, and occasional headless specimens.<ref>David, Lore Rose. 10 January 1943. <u>Miocene Fishes of Southern California</u> The Society</ref>
* † ''[[Megalampris keyesi]]'' is an extinct species estimated to be about {{Convert|4|m|abbr=on}} in length. Fossil remains date back to the late [[Oligocene]] of what is now [[New Zealand]], and it is the first fossil lampridiform found in the Southern Hemisphere.<ref name="JVP">Gottfried, Michael D., Fordyce, R.
