A small lanternshark found in the deep waters off Mauritius has been identified as a new species. The Etmopterus bulbosus measures 21.5cm in length and has a distinctive bulbous snout.
The species was discovered during a scientific research campaign by the Dr. Fridtjof Nansen research vessel in 2025. The shark was caught in a net at a depth of 400-500 meters in the southwestern Indian Ocean.
The Etmopterus bulbosus has a brown back with purple undertones and a black belly. It also features the characteristic luminous patterns of lanternsharks, which are known for their ability to produce light through bioluminescence.
The shark's dermal denticles, small tooth-like structures that cover its skin, are also distinctive. A cluster of enlarged denticles above the pectoral fin sets it apart from similar species.
The discovery of the Etmopterus bulbosus is significant, as it may be one of the smallest shark species in the world. However, only one specimen has been found, and its adult size is not yet known.
The new species has been recognized through a combination of physical characteristics and genetic analysis. The DNA analysis shows a 10.29% genetic distance from similar species, confirming its status as a distinct species.
The Etmopterus bulbosus may rival the dwarf lanternshark for the title of smallest shark species, but further research is needed to determine its adult size and confirm its status.

Three perspectives
Neutral
The discovery of the Etmopterus bulbosus is a significant finding in the field of marine biology. Further research is needed to learn more about this new species and its place in the ocean ecosystem. Scientists will be watching to see if more specimens are found and what they can reveal about the species' habits and habitats.
Positive
The discovery of the Etmopterus bulbosus is an exciting development for shark enthusiasts and marine biologists. It highlights the importance of continued exploration and research into the world's oceans, where new species are still being discovered. This finding may also shed new light on the diversity of shark species and their role in the marine ecosystem.
Negative
The discovery of the Etmopterus bulbosus also raises concerns about the impact of human activities on the ocean ecosystem. The deep waters off Mauritius are a unique and fragile environment, and the discovery of a new species highlights the need for continued conservation efforts to protect these areas. Further research is needed to understand the species' habitat and behavior, and to determine the potential threats it may face.
