Taxonomic Notes
This species has frequently been misidentified in the literature as Decapterus macarellus (W. Smith-Vaniz pers. comm. 2015).
Taxon distribution as listed in assessment
In the UAE, this species occurs only in the Sea of Oman. It is excluded from the Arabian Gulf. Globally, it is widespread in the tropical Indo-Pacific (Smith-Vaniz 1995, Mundy 2005, R. Myers pers. comm. 2016). This species has frequently been misidentified in the literature as Decapterus macarellus (W. Smith-Vaniz pers. comm. 2015). The depth range is 30 to 214 m (Mundy 2005).

Habitat
Habitat details as listed in assessment
This species schools mostly in open waters and is common in insular habitats (Smith-Vaniz 1984). It is occasionally seen in small groups along reef slopes adjacent to deep water in pursuit of zooplankton (Smith-Vaniz 1995, Kuiter and Tonozuka 2001, Mundy 2005). The maximum total lengthis 35 cm, although it is common to find individuals of 25 cm (Smith-Vaniz 1986). It lives to at least five years of age (Shiraishi et al. 2010).

Conservation
Threats listed in assessment
Fishing activity is not known to be driving declines in the UAE at this time. Corals in the UAE and Arabian Gulf have severely declined due to the increasing frequency of mass bleaching events caused by rising water temperatures, which is a consequence of climate change, as well as pervasive coastal development (Riegl et al. 2018, Burt et al. 2019).
