Young eels are a type of fish that can be found in many freshwater and saltwater habitats. They are usually referred to as ELVERS or LARVAE, depending on their age. ELVERS are juvenile eels that have recently migrated from the ocean to freshwater rivers and streams. LARVAE are even younger eels that have just hatched from eggs. Both ELVERS and LARVAE are important food sources for many species of fish, birds, and other animals.
