Geographic Range [top]

Range Description:Remorina albescens is widely distributed in tropical waters. In the Eastern Pacific area it is found from San Francisco to Chile, but it is rare north of the state of Baja California in Mexico. It is found in the Indian Ocean including waters around Reunion and Mauritius. In the western Atlantic it is found from Florida to Brazil, including the Gulf of Mexico. It is also found in the Western Pacific Ocean around Indonesia and China.

Population:There is no population information available for Remorina albescens.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Remorina albescens attaches itself to other species by a cephalic sucking disk on its head. Ninety percent of individuals are found on Manta Rays, but are also associated with 4 other hosts (O'Toole 2002). It is often found inside the gill chambers and mouth of its host. This species is found to a depth of 50 m.
Movement patterns:Full Migrant

Use and Trade [top]

Use and Trade: Remorina albescens is used in traditional Chinese medicines.

Threats [top]

Major Threat(s): This species is used within Traditional Chinese Medicine, however there is no indication that this is causing a decline in the population. It's association with Manta Rays may result in future population declines should Manta Rays continue to be impacted by anthropogenic pressures.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for Remorina albescens. However, the distribution of this species may fall within a number of marine protected areas.
