Etymology: silenus: Named after Silenus, a drunkard demigod who fell in a marsh on a revel and became covered with slime (Ref. 6885).
Eponymy: Silenus, in Greek mythology, was a companion and tutor to the wine-god Dionysus. He was usually drunk, and the binomial may have been inspired by the fact that the holotype was preserved in alcohol. (Ref. 128868), visit book page.

Espinhos dorsais (total) : 54 - 57; Raios dorsais (total) : 0; Espinhos anais: 0; Raios anais : 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).
