Combtooth lantern shark

<em>Etmopterus decacuspidatus</em>, the combtooth lantern shark, is a small deep-sea shark in the family Etmopteridae, assessed as Least Concern on the IUCN Red List. As a member of the lanternshark genus <em>Etmopterus</em>, the species likely possesses bioluminescent photophores along its ventral surface, a characteristic feature of the group used for counter-illumination and possibly intraspecific communication in the deep ocean. The combtooth designation references the multi-cusped tooth structure of the species. Lantern sharks are among the most species-rich shark genera and are distributed across deep oceanic environments worldwide. Specific habitat description and geographic range data are not available for this species in the current record. As with many deep-sea chondrichthyans, comprehensive ecological and biological information is limited. No quantitative biological trait data including body length or weight are recorded for this species.
