The Etmopterus brachyurus, or Short-tail Lanternshark, is a small, deepwater lanternshark restricted to areas like Japan, the Philippines and off eastern and western Australia. Found on the upper continental slope of the northwest Pacific ocean, 400-610 metres deep, this shark can be misidentified with other lanternsharks due to their poorly defined distribution and occurrence.
The Short-tail Lanternshark can reach up to 50 cm total length. Females are ovoviviparous and are reported to have five to 13 embryos per litter, with pups ranging in size from 11 to 13 cm in length. Males of this species reach maturity at 33 cm and females at 40 cm.
