Scomberesox simulans
Scomberesox simulans, the dwarf saury, is a species of ray-finned fish within the family Scomberesocidae, found in the Atlantic and Indian Ocean. It inhabits tropical and subtropical waters near the surface as a pelagic-oceanic species, migrating as the ocean warms in the spring and summer. It mainly feeds on planktonic organisms. The maximum length recorded was 13 centimeters in length, although the species is most commonly found at 9-10 centimeters in length. It is often confused as the juvenile form of the Atlantic saury.

Conservation
