The Tailface Sleeper (Calumia godeffroyi) has been assessed as Least Concern, owing to its widespread distribution across the Indian and Pacific Oceans. Although habitat degradation is occurring within parts of its range, this does not appear to represent a major threat to this species. Further research on the abundance of this species is needed to determine if this species is in fact rare.

Population [top]

Population:Many marine eleotrids are rare (Hoese and Roberts 2005). The Tailface Sleeper is widespread but is not commonly observed (E. Murdy pers. comm. 2009).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The Tailface Sleeper is associated with coral reefs and can be found resting on coral and rubble substrates. This species occurs at a depth of 7–30 m.

Threats [top]

Major Threat(s): The coral reefs in some areas of the Tailface Sleeper's range (e.g., in East Africa and Indonesia) have experienced regionalised and localised degradation due to bleaching, industrialisation, water pollution (sedimentation), destructive fishing practices and other human population pressures. In other parts of its range, the reefs are in good condition, so at present habitat degradation is not considered a major threat to the global population.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for Calumia godeffroyi.  However, its distribution may cover a number of marine protected area (MPA) designations.  Further research on  population trends is needed.
