Abstract

During metamorphosis from the leptocephalus larva to glass eel, which occurs before entering freshwater, eel larvae undergo marked changes in the somatic structures from the leaflike shape of the leptocephalus to the adult-like shape of the glass eel. “Glass eel” is defined here a developmental stage from the end of metamorphosis in the leptocephalus to the beginning of pigmentation (stage VA-VI A; Tesch 1977). Following this stage the young eels are called “elvers” (Tesch 1977). The glass eels and elvers are regarded as the same category at times when they are variously referred to as glass eels, elvers, and juveniles, and are often undistinguishable in the literature.
