It is a deep water shark and is found about 220 to 915 meters below the surface, on the upper continental slopes of the Gulf.

[2] Etmopteridae is a family commonly known as lanternsharks because the photophores on their ventral side produce light, making them bioluminescent.

[4] E. shultzi lives at a depth of about 220 to 915 meters below the surface, predominantly on the upper continental slopes of the Gulf of Mexico.

[4] It is endemic to the Gulf, and its range extends from the continental slopes of Eastern Mexico, Southern United States, and Western Florida.

[5] It has also been suggested that these lantersharks school in order to hunt food, but very little research has been done on their feeding behaviors and methods.

[4] Ovoviviparity is a method of reproduction in which there is internal fertilization and the developing young feed on the egg yolk.

[6] This is necessary when schooling together or finding a mate as the low levels of light would otherwise make locating each other extremely difficult.

[4] While no study has been done to determine the population status of E. shultzi specifically, there is evidence that the species has been negatively affected by the 2010 oil spill in the Gulf of Mexico.
