Scientific Name:	Acanthennea erinacea
Species Authority:	(Martens, 1898)

Assessment Information [top]

Red List Category & Criteria:	Vulnerable B1ab(iii)+2ab(iii) ver 3.1
Year Published:	2009
Assessor/s:	Gerlach, J.
Reviewer/s:	Miller, R.M., Pollock, C.M. & Seddon, M.
Contributor/s:
Justification: This species' restricted range (EOO = 300 km²; AOO = 25 km²; known from 10 locations), coupled with habitat degradation caused by invasive plant species, renders it vulnerable to extinction. Although this species is not tolerant of habitat degradation, at present it appears to be stable across its current range.

Geographic Range [top]

Range Description:	Endemic to the Seychelles, this snail is found on Mahé and Silhouette islands. Its area of occupancy (AOO) has been estimated to measure 25 km² and its extent of occurrence (EOO) is 300 km².
Countries:	Native: Seychelles (Seychelles (main island group))

Population [top]

Population:	In 2005, the population was estimated to contain 90,000 individuals.
Population Trend:	Stable

Habitat and Ecology [top]

Habitat and Ecology:	Restricted to high forest, this is a predatory species that feeds on small invertebrates (including arthropods).
Systems:	Terrestrial

Threats [top]

Major Threat(s):	This species is vulnerable to habitat degradation. Currently, invasive species (e.g., Cinnamomum verum) which alter this snail's habitat are the principle threat. Small-scale wood plantations and farms have caused habitat degradation in the past.
