Glass eels typically refers to an intermediary stage in the eel’s complex life. The term typically refers to a transparent glass eel of the family Anguillidae. These are the freshwater eels that spawn in the ocean, and then enter estuaries as glass eels and swim upstream to live in freshwater during their juvenile growth phase. As the glass eels enter freshwater they start to become pigmented and are typically referred to as elvers. The elvers grow larger and are referred to as yellow eels, which are the juvenile stage of eels before their reproductive maturation begins.
