|Scientific Name:||Himantura schmardae (Werner, 1904)|
|Taxonomic Notes:||Compagno (1999) considered this a doubtful species and more studies are required to elucidate the taxonomic aspects of this species. The phylogenetic status and affinities of tropical Western Atlantic and Eastern Pacific Himantura are under review.|
|Red List Category & Criteria:||Data Deficient ver 3.1|

A large (to 200 cm disc width) tropical stingray that is distributed in the Western Central and Southwest Atlantic Ocean from Mexico to Brazil including the Lesser and Greater Antilles. Almost no data is available on its habitat, biology, ecology and population trends. However, it is caught as bycatch and used as a subsistence food source. Base-line studies, including taxonomic aspects, need to be elucidated for this species. Given its probable inshore occurrence in fished areas its conservation status will need to be reassessed once data are collected, particularly concerning catch levels. In the first instance though, the species' taxonomic status needs resolution.
|Range Description:||This tropical species is reportedly found on sandy bottoms and occasionally near coral reefs (Michael 1983) in the Gulf of Campeche (Mexico) to Brazil including the Lesser and Greater Antilles (Stehmann et al. 1978, Cervigón et al. 1992, Claro 1994, Almeida et al. in press). It has rarely been observed in the Amazon estuary region (Almeida et al. in press).|

This species is reportedly caught as bycatch in artisanal and industrial fisheries (hooking and netting). This species is also taken as a subsistence food source.
Intrinsic factors probably also represent a threat for this species as to most other elasmobranchs species (Camhi et al. 1998).
Research actions are urgently needed for this species. Preliminary base-line studies are required to obtain data on the biology, ecology, uses and fishery data of this species, and in the first instance taxonomic status.
Captures should also be monitored to observe if they are within a sustainable range.
Habitat maintenance and conservation should also be considered as conservation actions for this species.
The development and implementation of management plans (national and/or regional e.g., under the FAO International Plan of Action for the Conservation and Management of Sharks: IPOA-Sharks) are required to facilitate the conservation and sustainable management of all chondrichthyan species in the region. See Anon. (2004) for an update of progress made by nations in the range of H. schmardae.
