Distribution. Mostly found in the tropical waters of the eastern Pacific; also in NW Indian Ocean and South China Sea ( Vinogradov et al. 1996, Zeidler 2003). In the eastern Pacific it ranges from 12°56’N, 104°15’W to 17°55’N, 119°50’W ( Shih & Hendrycks 2003).

Remarks. Recorded as a rare species by Vinogradov et al. (1996), V. longicarpus is also considered a tropical species ( Shih & Hendrycks 2003) which appears to be rather common in the Gulf of California where it has been previously reported by Gasca & Browne (2018) in association with the salp Metcalfina hexagona (Quoy & Gaimard, 1824) at 315 m depth. Shih & Hendrycks (2003) found it from the surface to 225 m depth. It has been recorded as the 14 th most abundant species in the Mexican tropical Pacific by Gasca et al. (2012).
