Larvae of most species of Cyclothone and Gonostoma have been described (Table Gonostomatidae). Body slender with straight gut, to 60% of body length, with conspicuous gas bladder. Pigmentation behind eyes in Gonostoma, not in Cyclothone (Cyclothone braueri). Pigmentation pattern useful for identification to species level in Cyclothone (Ozawa and Oda, 1986) and Gonostoma (Ahlstrom et al., 1984c).
