Distribution. Circumtropical (Vinogradov et al. 1996). In the eastern Pacific from the west coast of Baja California to the Galapagos Islands (García Madrigal 2007).
Remarks. According to Siegel-Causey (1982: 177, fig. 69), L. bengalensis is strongly epipelagic but features a very wide overall depth distribution, ranging from surface to depths> 2200 m. Reported in surface waters by Vinogradov et al. (1996). García Madrigal (2007) reported a 0‒3220 m depth distributional range. It was one of the two most abundant species in this survey.
