The fringefin lanternshark, Etmopterus schultzi, is a small deepwater shark with a pretty widespread range in the Gulf of Mexico and Caribbean Sea compared to other Etmopterus species. This small shark, only getting up to ~30 cm total length (TL) is found to prefer the upper continental slopes of its range, seen at depths of 220 down to 915 m.

The fringefin lanternshark is the most common species of the Etmopteridae family in its range in the Gulf of Mexico. Like others in the family, little known about it although it is sometimes taken as bycatch in deepwater demersal fisheries, but often discarded. Like many deepwater chondrichthyan species, more information on their biology, ecology and how fisheries impact them is needed. The IUCN has assessed these animals as Least Concern (LC).
