Scientific Name: Holothuria inornata Semper, 1868

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1

This species is distributed in the eastern tropical Pacific. It has been reported from illegal fisheries in El Salvador. There are some issues regarding the species taxonomy, and whether it is distinct from H. keferstenii. It may be collected in other parts of its range, but no information is available. It occurs in shallow habitat and is therefore very accessible. This species is listed as Data Deficient until more information is obtained on its taxonomy, distribution and threats (mainly fisheries).
