Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 54 - 57; Raios dorsais moles (total) : 0; Espinhos anais: 0; Raios anais moles: 29 - 30. Caudal rounded.
Adults occur near bottom (Ref. 2850). Young to 7.2 cm are pelagic or bathypelagic, usually associated with jellyfish (Ref. 6885). Juveniles take shelter under the medusae and are often mistaken for medusafish Icichthys lockingtoni (Ref. 50276).
