Paraclinus magdalenae has been assessed as Endangered. This species has a restricted distribution in Magdalene Bay which is considered to be one location, and an extent of occurrence of less than 5,000 km2. It is threatened by habitat degradation from coastal development, pollution, intensive tourism development and extraction activities.

Geographic Range [top]

Range Description:Paraclinus magdalenae is only known from a few specimens in the immediate vicinity of Magdalena Bay, Baja California, Mexico. In 1969, Rosenblatt and Parr took samples at appropriate depths along the coast, and Paraclinus magdalenae was not found in any other areas. The area in which this species is distributed is approximately 1,131 km2.

Threats [top]

Major Threat(s):

This species is threatened by habitat loss from coastal development, urban and industrial pollution, massive tourism development and various potentially harmful extractive activities within its restricted range (Hastings and Fischer 2001). Effluent, including domestic untreated sewage and industrial waste is discharged directly into Magdalena Bay, and intertidal near-shore and wetland areas are being degraded (School for Field Studies 2004).

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place for Paraclinus magdalenae. Further research is needed to determine the abundance of this species and how it is affected by threats such as pollution.
