Fig. 9 View Figure 9

This mesopelagic predatory species is widespread in tropical oceans ( Choy et al. 2013, Mthethwa et al. 2023, Fricke et al. 2024). Its larvae are commonly captured nearshore in the Hawaiian Archipelago ( Miller et al. 1979). Adults have been recorded from Clipperton Atoll ( Fourriére et al. 2014). Based on COI sequences, eggs and larvae have been recorded from the Ninety East Ridge of the eastern Indian Ocean ( Zhang et al. 2021) and larvae have been recorded from Hawaiian waters ( Xing et al. 2022). G. serpens larvae are characterised by strong pre-opercular spines, well-developed dorsal and pelvic fin ray spines, with pigmentation on the brain, dorsal surface of the gut, the mid-body and along the body margin under the first dorsal fin ( Moser 1996).
