Lesson plan
Greeneye
Greeneyes are deep-sea aulopiform marine fishes in the small family Chlorophthalmidae. Thought to have a circumglobal distribution in tropical and temperate waters, the family contains just 18 species in two genera. The family name Chlorophthalmidae derives from the Greek words chloros meaning "green" and ophthalmos meaning "eye". Some species are of interest to commercial and subsistence fisheries; the fish are made into fish meal or sold fresh. The only known prehistoric member of this group is Omiodon, a stem-chlorophthalmid known from a complete fossil skeleton from the early Eocene of Italy. Acrognathus from the Cenomanian of England & Lebanon was previously classified in this family, but its classification into this family is now refuted due to its prominent scutes, which are not present on definite chlorophthalmids. Another potential fossil genus, Iniomus, is known from isolated scales from the Late Eocene of California.
