|Scientific Name:||Elops smithi|
|Species Authority:||McBride, Rocha, Ruiz-Carus & Bowen, 2010|
|Taxonomic Notes:||Elops saurus was recently split into two largely allopatric species, E. saurus and E. smithi (McBride et al. 2010). In Florida waters, E. saurus and E. smithi may occur sympatrically at early life stages, though this does not appear to persist into the adult stage (McBride and Horodysky 2004). E. saurus and E. smithi can be differentiated by myomere or vertebral counts; the more northern E. saurus is characterized by a higher count while the more southern E. smithi exhibits a lower count (Smith 1989, McBride and Horodysky 2004, McBride et al. 2010). These phenotypic differences are corroborated by genetic data (McBride et al. 2010). The sequence divergence in mtDNA cytochrome b (d = 0.023-0.029) between E. smithi and E. saurus is similar to or greater than that measured between recognized species of Elops in different ocean basins (McBride et al. 2010). We recommend the vernacular name Malacho, which is already used for Elops in several countries bordering the Caribbean basin." (McBride et al. 2010; see 'etymology').|

Elops smithi occurs along the northern coast of South America, in the Caribbean Sea, and throughout the Bahamas and southwestern Gulf of Mexico. Little information exists regarding population status, ecology, life history, fisheries interactions or potential threats. Only eight specimens of this estuarine species have been reported from museum records. Therefore, we consider this species Data Deficient.
Elops smithi occurs along the northern coast of South America, in the Caribbean Sea, and throughout the Bahamas and southwestern Gulf of Mexico. Leptocephali and juveniles are also collected along the eastern seaboard of North America, the northern and eastern Gulf of Mexico and Bermuda but these represent waifs or vagrants (Smith 1989, Smith-Vaniz et al. 1999, McBride et al. 2010).

|Population:||Only eight specimens have been reported from museum records, including specimens at the University of Florida and the Academy of Natural Sciences at Drexel University in the United States (accessed through the Fishnet2 Portal, www.fishnet2.net, 2011-05-14). Although it is possible that E. smithi may be present in United States landings data, it is extremely likely that the catch is predominately E. saurus. Little is known about landings data throughout most of this species' range.|
|Habitat and Ecology:||
Elops smithi is found in a wide range of salinities. Mature adults and early-life-history stages are found in offshore, marine habitats, where spawning presumably occurs (Gehringer 1959, Santos-Martínez and Arboleda 1993, McBride and Horodysky 2004). Transforming larvae and subadults are found throughout estuaries, as far up as the oligohaline zone, as well as in hypersaline lagoons (Carles 1967, McBride et al. 2001, McBride and Horodysky 2004). They are found in hypersaline lagoons up to 49.25 ppt (Carles 1967). Carles (1967) used unvalidated scales to age fish, noting fish as old as age two were common in lagoons of Cuba. Size at age indicate slow growth rates, about 14 cm FL at first annulus formation. Carles (1967) reported fish up to 40 cm FL and noted age one as the age of maturity. Diet included mostly penaeid shrimp, less commonly Engraulis fish and some swimming crabs. Juvenile E. smithi reach 130 mm SL by their first winter in Florida (McBride and Horodysky 2004).
Elops smithi utilizes estuarine areas and hyper-saline lagoons; changes in the the quality of this habitat may affect this species' population dynamics. Although this species may not be closely associated with any single habitat, it may be adversely affected by urbanization.
|Conservation Actions:||In Florida, the prohibition of the use of tarp nets and entangling nets is in place for the commercial fishery of this species (Florida Fish and Wildlife Conservation Commission 2008). Its distribution overlaps with marine reserves in parts of its range. There are no recreational size or bag limits in place (MacDonald pers. comm. 2011). No species-specific information exists south of Florida.|
