Enneapterygius namarrgon has been assessed as Endangered under criterion B1ab(iii). This species is endemic to the bauxite rocks of Gove Peninsula, Australia, which is considered one location, and has an extent of occurrence less than 5000 km2. This species is threatened by habitat degradation caused by the mining of bauxite rocks. Australia is the world's leading producer of bauxite and it is predicted that the resource life for existing bauxite operations is on average 70 to 75 years, therefore the threat to this species will continue in the future. Monitoring of this species and its threats is needed to prevent an increase in threat category being missed in the future. Research is needed on potential conservation measures for this species.

|Population:||There is no population information available for Enneapterygius namarrgon.|
|Habitat and Ecology:||Enneapterygius namarrgon is a coastal species, endemic to bauxite rocks (R. Fricke pers. comm. 2008).|
|Major Threat(s):||Enneapterygius namarrgon is only found on bauxite rocks of the Gove Peninsula, Australia. Bauxite is the most important aluminium ore. Over 85% of the bauxite mined globally is converted to alumina for the production of aluminium metal. Australia is the World’s leading producer of bauxite and alumina. Production totalled 62 Mt of bauxite or 36% of the world production in 2006. The Gove mine contains the world's highest grade deposits of Bauxite. Due to its restricted association with bauxite rock, it is likely that this species is being threatened by bauxite mining (R. Fricke pers. comm. 2008). It is predicted that the resource life for existing bauxite operations is on average 70 to 75 years, therefore the threat to this species will continue in the future.|
There are no known species-specific conservation measures in place for Enneapterygius namarrgon.
Monitoring of this species and its threats should be undertaken to accurately determine the impact of bauxite mining on the population of this species, better enabling conservation measures to be implemented.
