Kingdom Phylum Class Order Family
Animalia Arthropoda Malacostraca Decapoda Glypheidae

Scientific Name: Neoglyphea inopinata
Species Authority: Forest & De Saint Laurent, 1975
Taxonomic Notes: This species is regarded as a living fossil, with very similar fossils dating from the Jurassic period. There is a debate on whether it is part of the coral lobsters or the spiny lobsters.

There is very little information known about this living fossil species. It is only known from two locations and from a small number of specimens. The threats are unknown, although trawling could be a potential threat to this species as it has a localised distribution in muddy habitats. This species is listed as Data Deficient. Further research is needed on the distribution, abundance and possible threats is needed before a more accurate assessment of conservation status can be made.

Population [top]

Population:This species is known from 17 specimens from two locations. There is no population information available. The first specimen was caught in a trawl from the research ship the Albatross in 1908, but not described until 1975. There were surveys carried out to try to catch the species again in the Timor Sea in 1978, and three specimens were found. Surveys in the Philippines in 2007 could not find any (P. Ng pers. comm. 2009).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species lives on firm, muddy substrates on slopes at depths of 150-300m.

Threats [top]

Major Threat(s): Threats to this species are unknown. Deep water trawling vessels in the Philippines may be a threat, though there is not a high level of trawling at the present time. This species appears to be very localised which makes it more susceptible to threats.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for this species.

Further surveys of this species are needed to better understand distribution, abundance and possible threats.
