Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2010
Date Assessed: 2007-05-24
Assessor(s): Findley, L. & Acero, A.
Reviewer(s): Carpenter, K., Polidoro, B. & Livingstone, S. (Global Marine Species Assessment Team)
This species is restricted to the upper Gulf of California. It is a shallow water species that occurs in estuarine habitats that are increasingly disturbed by coastal development and aquaculture. However, very little is known about the population status of this species and the impact of current threats. It is therefore assessed as Data Deficient.
